Tropical Cyclone KENANGA Southern Hemisphere Summary |
WTXS21 PGTW 132100
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
160 NM EITHER SIDE OF A LINE FROM 6.9S 92.5E TO 11.5S 88.4E
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 23 TO 28 KNOTS. METSAT
IMAGERY AT 131800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 7.6S 91.4E. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 16
KNOTS.
2. REMARKS: (1) THE AREA OF CONVECTION (INVEST 91S) PREVIOUSLY
LOCATED NEAR 6.8S 92.8, IS NOW LOCATED NEAR 7.6N 91.4E,
APPROXIMATELY 428 NM NORTHWEST OF COCOS ISLANDS. ENHANCED
INFRARED SATELLITE IMAGERY AND A PARTIAL 131920Z AMSR2 89 GHZ
MICROWAVE IMAGE SHOW A CONSOLIDATING LOW LEVEL CIRCULATION (LLC)
WITH FRAGMENTED, FORMATIVE BANDING AND PERSISTENT DEEP CONVECTION.
UPPER LEVEL ANALYSIS INDICATES MODERATE TO HIGH (20-30 KNOT)
VERTICAL WIND SHEAR AND VERY GOOD POLEWARD OUTFLOW. SEA SURFACE
TEMPERATURES (26-28 CELSIUS) ARE FAVORABLE FOR DEVELOPMENT. A RECENT
PARTIAL ASCAT PASS REVEALS A BROAD, SYMMETRIC CIRCULATION WITH
STRONGER WINDS WRAPPING INTO THE LLC FROM THE NORTHEAST. GLOBAL
MODELS ARE IN GOOD AGREEMENT THAT 91S WILL TRACK SOUTHWESTWARD AND
INTENSIFY OVER THE NEXT SEVERAL DAYS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1001 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
142100Z.//

REMARKS:
152100Z POSITION NEAR 9.1S 91.2E.
TROPICAL CYCLONE 06S (SIX), LOCATED APPROXIMATELY 1116 NM EAST OF
DIEGO GARCIA, HAS TRACKED SOUTH-SOUTHEASTWARD AT 02 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
DEPICTS DEEP CONVECTION FLARING OVER A DEFINED LOW LEVEL CIRCULATION
CENTER (LLCC). A 151500Z ASCAT PASS REVEALED A BROAD WIND FIELD WITH
30 KT WINDS WRAPPED AROUND THE CENTER, AND AREAS OF 35 KT WINDS
DISPLACED FROM THE CENTER. THE INITIAL POSITION IS BASED ON THE
ASCAT AMBIGUITIES WITH FAIR CONFIDENCE. THE INITIAL INTENSITY IS
ASSESSED AT 35 KTS BASED ON THE ASCAT PASS, WHICH IS BETWEEN THE
PGTW AND KNES DVORAK CURRENT INTENSITY ESTIMATES OF T2.0 (30 KTS)
AND T3.0 (45 KTS). TC 06S IS BENEFITING FROM EXCELLENT POLEWARD AND
EQUATORWARD OUTFLOW AND WARM (27 DEGREES CELSIUS) SEA SURFACE
TEMPERATURES, ALTHOUGH MODERATE TO HIGH (20-30 KT) VERTICAL WIND
SHEAR (VWS) IS LIMITING ITS RATE OF DEVELOPMENT. TC 06S IS FORECAST
TO TRACK SOUTHWESTWARD AS A NEAR-EQUATORIAL RIDGE TO THE WEST BUILDS
IN TO THE REGION. TC 06S IS FORECAST TO GRADUALLY INTENSIFY UNDER
MARGINAL ENVIRONMENTAL CONDITIONS TO A PEAK OF 55 KTS AT TAU 72. THE
SYSTEM WILL THEN FLIRT WITH THE 26 DEGREE CELSIUS ISOTHERM AS IT
MOVES DUE WESTWARD INTO DRIER AIR, AND DIVERGENCE ALOFT WILL
DECREASE, LEADING TO GRADUAL WEAKENING AFTER TAU 96. DYNAMIC MODEL
GUIDANCE IS IN FAIR AGREEMENT WITH THE EXCEPTION OF COAMPS-NAVGEM,
WITH 320NM OF MODEL SPREAD AT TAU 96 NOT COUNTING COAMPS-NAVGEM, AND
SOME VARIATION IN ALONG-TRACK SPEED. THE JTWC FORECAST IS PLACED
WITH FAIR CONFIDENCE BEHIND AND SOUTH OF THE MULTI-MODEL CONSENSUS
IN THE NEAR-TERM, TOWARDS THE GFS AND NAVGEM SOLUTIONS, TO ACCOUNT
FOR SLOW CURRENT SOUTHEASTWARD MOTION. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 151800Z IS 18 FEET. NEXT WARNINGS AT 160300Z, 160900Z,
161500Z AND 162100Z.

REMARKS:
160300Z POSITION NEAR 9.3S 91.2E.
TROPICAL CYCLONE 06S (KENANGA), LOCATED APPROXIMATELY 1123 NM
EAST OF DIEGO GARCIA, HAS TRACKED SOUTH-SOUTHEASTWARD AT 02 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR) SATELLITE
IMAGERY DEPICTS AN EXPANDING CENTRAL DENSE OVERCAST FEATURE FLARING
OVER THE LOW LEVEL CIRCULATION CENTER (LLCC). A 252119Z SSMIS 91GHZ
MICROWAVE IMAGE SHOWS THAT DEEP CONVECTION IS SHEARED JUST TO THE
EAST OF THE LLCC, THOUGH THE LLCC IS STILL OBSCURED BY CIRRUS CLOUDS
IN EIR IMAGERY. THE INITIAL POSITION IS BASED ON ANIMATED EIR
IMAGERY AND THE EXTRAPOLATED 152119Z SSMIS 91GHZ IMAGE WITH LOW
CONFIDENCE. THE INITIAL INTENSITY IS ASSESSED AT 40 KTS, SLIGHTLY
ABOVE THE PGTW AND KNES DVORAK CURRENT INTENSITY ESTIMATES OF T2.5
(35 KTS) BASED ON THE IMPROVING STRUCTURE. TC 06S IS BENEFITING FROM
GOOD POLEWARD AND EQUATORWARD OUTFLOW AND WARM (27 DEGREES CELSIUS)
SEA SURFACE TEMPERATURES, ALTHOUGH HIGH AND BUILDING (20-30 KT)
VERTICAL WIND SHEAR (VWS) IS LIMITING ITS RATE OF DEVELOPMENT AND
SEPARATING THE DEEP CONVECTION FROM THE LLCC. TC 06S IS FORECAST TO
TRACK TO THE SOUTHWEST AS A NEAR-EQUATORIAL RIDGE TO THE WEST BUILDS
IN TO THE REGION. HOWEVER, RECENT MODEL RUNS HAVE CONTINUALLY
PREDICTED THE TURN TO THE SOUTHWEST, WHICH HAS NOT YET BEEN
REALIZED. TC 06S IS FORECAST TO GRADUALLY INTENSIFY UNDER MARGINAL
ENVIRONMENTAL CONDITIONS TO A PEAK OF 55 KTS AT TAU 48. THE SYSTEM
WILL THEN APPROACH THE 26 DEGREE CELSIUS ISOTHERM AS IT MOVES DUE
WESTWARD INTO DRIER AIR, AND DIVERGENCE ALOFT WILL DECREASE, LEADING
TO GRADUAL WEAKENING AFTER TAU 72. DYNAMIC MODEL GUIDANCE IS IN FAIR
AGREEMENT WITH THE EXCEPTION OF COAMPS-NAVGEM AND COAMPS-GFS WHICH
DIVERGE DUE WEST AFTER TAU 72. THERE IS 157 NM OF SPREAD BETWEEN
MODEL TRACKERS AT TAU 72, AND SIGNIFICANT VARIATION IN ALONG-TRACK
SPEED. GFS IS NOW ROUGHLY ALIGNED WITH THE MULTI-MODEL CONSENSUS,
BUT WITH A FASTER ALONG-TRACK SPEED. ECMWF IS JUST NORTH OF
CONSENSUS FOR MOST OF THE FORECAST PERIOD, AND ALSO PREDICTS A
FASTER ALONG-TRACK SPEED. THE NAVGEM AND GALWEM MODEL SOLUTIONS ARE
SOUTH OF AND SLOWER THAN CONSENSUS. THE JTWC FORECAST TRACK IS
HEDGED BEHIND AND EAST OF THE MULTI-MODEL CONSENSUS TRACK IN THE
NEAR-TERM DUE TO SLOW OBSERVED SOUTHEASTWARD CURRENT MOTION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 160000Z IS 16 FEET. NEXT WARNINGS AT
160900Z, 161500Z, 162100Z AND 170300Z.//

REMARKS:
160900Z POSITION NEAR 10.0S 90.6E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 1097 NM
EAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 07 KNOTS OVER
THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI)
DEPICTS A PARTIALLY-EXPOSED, BROAD SYSTEM WITH DEEP CONVECTION
CONSOLIDATING OVER THE LOW-LEVEL CIRCULATION CENTER. A 160308Z MHS
89GHZ IMAGE DEPICTS A PARTIALLY-EXPOSED LLCC WITH DEEP CONVECTIVE
BANDING WRAPPING BROADLY INTO THE WESTERN QUADRANT. BASED ON THE
MSI, THERE IS FAIR CONFIDENCE IN THE INITIAL POSITION. UPPER-LEVEL
ANALYSIS INDICATES FAVORABLE EQUATORWARD AND POLEWARD OUTFLOW OVER
THE WESTERN AND SOUTHERN SEMICIRCLES WITH STRONG (25 TO 30 KNOTS)
EASTERLY VERTICAL WIND SHEAR LIMITING OUTFLOW OVER THE EASTERN
SEMICIRCLE. DUE TO THE OVERALL FAVORABLE CONDITIONS, THE INITIAL
INTENSITY HAS INCREASED TO 45 KNOTS BASED ON DVORAK INTENSITY
ESTIMATES OF T3.0 (45 KNOTS) FROM PGTW AND KNES. TC 06S IS FORECAST
TO TRACK SOUTHWESTWARD THROUGH TAU 72 ALONG THE NORTHWEST PERIPHERY
OF THE SUBTROPICAL RIDGE (STR). AFTER TAU 72, TC KENANGA WILL TURN
WEST-SOUTHWESTWARD TO WESTWARD UNDER THE STEERING INFLUENCE OF A
BUILDING STR. DYNAMIC MODEL GUIDANCE IS IN FAIR AGREEMENT,
THEREFORE, THERE IS MODERATE CONFIDENCE IN THE JTWC FORECAST TRACK.
TC 06S SHOULD CONTINUE TO INTENSIFY UNDER FAVORABLE CONDITIONS
THROUGH TAU 36 TO A PEAK INTENSITY OF 60 KNOTS. AFTER TAU 36,

REMARKS:
161500Z POSITION NEAR 10.3S 90.1E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 1082 NM
EAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 07 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
DEPICTS PERSISTENT DEEP CONVECTION OVER THE WESTERN SEMICIRCLE OF AN
ELONGATED LOW-LEVEL CIRCULATION CENTER (LLCC). A 161232Z SSMIS 37GHZ
IMAGE SHOWS A PARTIALLY-EXPOSED, DEFINED LLCC POSITIONED ON THE
EASTERN EDGE OF A DEEP CONVECTIVE BAND. UPPER-LEVEL ANALYSIS
INDICATES FAVORABLE EQUATORWARD AND POLEWARD OUTFLOW OVER
THE WESTERN AND SOUTHERN SEMICIRCLES WITH STRONG (25 TO 30 KNOTS)
EASTERLY VERTICAL WIND SHEAR LIMITING OUTFLOW OVER THE EASTERN
SEMICIRCLE. DUE TO THE OVERALL FAVORABLE CONDITIONS, THE INITIAL
INTENSITY HAS INCREASED TO 50 KNOTS, HEDGED ABOVE DVORAK INTENSITY
ESTIMATES OF T3.0 (45 KNOTS) FROM PGTW AND KNES. TC 06S IS FORECAST
TO TRACK SOUTHWESTWARD THROUGH TAU 72 ALONG THE NORTHWEST PERIPHERY
OF THE SUBTROPICAL RIDGE (STR). AFTER TAU 72, TC KENANGA WILL TURN
WEST-SOUTHWESTWARD TO WESTWARD UNDER THE STEERING INFLUENCE OF A
BUILDING STR. DYNAMIC MODEL GUIDANCE IS IN FAIR AGREEMENT,
THEREFORE, THERE IS MODERATE CONFIDENCE IN THE JTWC FORECAST TRACK.
TC 06S SHOULD CONTINUE TO INTENSIFY UNDER FAVORABLE CONDITIONS
THROUGH TAU 36 TO A PEAK INTENSITY OF 65 KNOTS. AFTER TAU 48,
CONDITIONS WILL GRADUALLY DEGRADE WITH COOLER SST AND WEAKER
DIFFLUENCE ALOFT LEADING TO A GRADUAL WEAKENING TREND. MORE
SIGNIFICANT WEAKENING IS EXPECTED AFTER TAU 72 AS THE SYSTEM
INTERACTS WITH A WEAK BAROCLINIC ZONE AND ENTRAINS COOLER, DRIER
AIR. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 161200Z IS 20 FEET. NEXT

REMARKS:
170900Z POSITION NEAR 12.7S 86.8E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 927 NM
EAST-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 13
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS A CENTRAL DENSE OVERCAST (CDO) FEATURE OBSCURING THE
LOW-LEVEL CIRCULATION CENTER (LLCC). A 170241Z GMI COMPOSITE IMAGE
SHOWS A COMPACT SYSTEM WITH CURVED BANDING WRAPPING INTO A DEFINED
LLCC, WHICH IS POSITIONED ON THE EASTERN EDGE OF THE CDO. UPPER-
LEVEL ANALYSIS INDICATES FAVORABLE POLEWARD OUTFLOW WITH MODERATE TO
STRONG (20 TO 30 KNOTS) EASTERLY VERTICAL WIND SHEAR LIMITING
OUTFLOW OVER THE EASTERN SEMICIRCLE. THE INITIAL INTENSITY IS
ASSESSED AT 55 KNOTS BASED ON A DVORAK INTENSITY ESTIMATE OF T3.5
(55 KNOTS) FROM KNES. TC 06S IS FORECAST TO TRACK WEST-SOUTHWESTWARD
TO SOUTHWESTWARD THROUGH TAU 72 ALONG THE NORTHWEST PERIPHERY
OF THE SUBTROPICAL RIDGE (STR). AFTER TAU 72, TC KENANGA WILL TURN
WESTWARD UNDER THE STEERING INFLUENCE OF A BUILDING STR. DYNAMIC
MODEL GUIDANCE IS IN FAIR AGREEMENT, THEREFORE, THERE IS MODERATE
CONFIDENCE IN THE JTWC FORECAST TRACK. TC 06S SHOULD CONTINUE TO
INTENSIFY UNDER GENERALLY FAVORABLE CONDITIONS THROUGH TAU 48 TO A
PEAK INTENSITY OF 75 KNOTS. AFTER TAU 72, CONDITIONS WILL GRADUALLY
DEGRADE AS THE SYSTEM INTERACTS WITH A WEAK BAROCLINIC ZONE AND
ENTRAINS COOLER, DRIER AIR. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
170600Z IS 21 FEET. NEXT WARNINGS AT 171500Z, 172100Z, 180300Z AND

REMARKS:
172100Z POSITION NEAR 13.2S 85.0E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 840 NM
EAST-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT 11
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS AN ASYMMETRIC CENTRAL DENSE OVERCAST WITH
SIGNIFICANT SPIRAL RAIN BANDS IN THE NORTHERN AND SOUTHERN
QUADRANTS. THE INITIAL POSITION IS PLACED WITH FAIR CONFIDENCE BY
EXTRAPOLATING FROM A 171557Z METOP-A ASCAT PASS WHICH SHOWS A CLEAR
CENTER AND THE STRONGEST WINDS TO THE SOUTH OF THE LOW LEVEL
CIRCULATION CENTER (LLCC). THE UPPER LEVELS ARE OVERALL FAVORABLE
WITH DECENT POLEWARD AND EQUATORWARD OUTFLOW CHANNELS OVERCOMING
MODERATE TO STRONG (20 TO 25 KNOTS) VERTICAL WIND SHEAR. THE INITIAL
INTENSITY OF 65 KNOTS IS CONSISTENT WITH DVORAK CURRENT INTENSITY
ESTIMATES OF T4.0 (65 KNOTS) FROM PGTW AND KNES. TC 06S WILL TRACK
WEST-SOUTHWESTWARD TO SOUTHWESTWARD FOR THE DURATION OF THE FORECAST
AS IT FOLLOWS THE NORTHERN PERIPHERY OF A CONSTANTLY RE-ORIENTING
SUBTROPICAL RIDGE (STR). LATE IN THE FORECAST PERIOD, TC 06S MAY
BEGIN TO EXPERIENCE DIRECT CYCLONE INTERACTION (DCI) WITH A SECOND
TROPICAL CYCLONE (CURRENTLY 92S) TO THE WEST. DESPITE DYNAMIC MODEL
GUIDANCE GENERALLY AGREEING WITH THE JTWC FORECAST TRACK, THERE IS
LOW CONFIDENCE BECAUSE THE SPREAD IS FAIRLY LARGE WITH THE UNCERTAIN
STEERING ENVIRONMENT AND THE POTENTIAL FOR DCI LATE IN THE FORECAST
PERIOD. TC 06S SHOULD GRADUALLY INTENSIFY UNDER GENERALLY FAVORABLE
CONDITIONS TO 80 KNOTS BY TAU 36. AFTER TAU 48, CONDITIONS WILL
BECOME MODERATELY UNFAVORABLE AND TC 06S IS EXPECTED TO WEAKEN.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 171800Z IS 23 FEET. NEXT WARNINGS

REMARKS:
180300Z POSITION NEAR 13.8S 84.4E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 819 NM
EAST-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 09
KNOTS (KTS) OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS DEEP CONVECTIVE RAIN BANDS WRAPPING INTO
AN OBSCURED LOW LEVEL CIRCULATION CENTER (LLCC). THE ANIMATED
IMAGERY REVEALED BRIEF PERIODS WHERE AN EYE APPEARED TO BE FORMING,
ONLY TO BE OBSCURED AGAIN A FRAME OR TWO LATER. THERE IS FAIR
CONFIDENCE IN THE INITIAL POSITION BASED ON A 172235Z SSMIS 37 GHZ
PARTIAL MICROWAVE IMAGE WHICH SHOWS THE WESTERN EDGE OF THE
DEVELOPING EYEWALL. THE SURROUNDING ENVIRONMENT IS MODERATELY
FAVORABLE WITH A POCKET OF LOW (10-15 KT) VERTICAL WIND SHEAR, GOOD
RADIAL OUTFLOW, AND MARGINAL (26-27 CELSIUS) SEA SURFACE
TEMPERATURES. THE INITIAL INTENSITY OF 70 KNOTS IS CONSISTENT WITH
DVORAK CURRENT INTENSITY ESTIMATES OF T4.0-T4.5 (65-77 KTS). TC 06S
WILL TRACK WEST-SOUTHWESTWARD TO SOUTHWESTWARD FOR THE DURATION OF
THE FORECAST AS IT FOLLOWS THE PERIPHERY OF A SHIFTING SUBTROPICAL
RIDGE (STR) TO THE SOUTH. LATE IN THE FORECAST PERIOD, TC 06S MAY
BEGIN TO EXPERIENCE DIRECT CYCLONE INTERACTION (DCI) WITH A SECOND,
DEVELOPING TROPICAL CYCLONE (CURRENTLY 92S) TO THE WEST. TC 06S
SHOULD GRADUALLY INTENSIFY TO 80 KNOTS BY TAU 36. AFTER TAU 48,
CONDITIONS SHOULD BECOME UNFAVORABLE AND TC 06S IS EXPECTED TO
WEAKEN. DESPITE GOOD GENERAL AGREEMENT IN DYNAMIC MODEL GUIDANCE,
THERE IS LOW CONFIDENCE IN THE JTWC TRACK FORECAST BECAUSE THE
SPREAD IS FAIRLY LARGE AND THE POTENTIAL FOR DCI LATE IN THE
FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 180000Z IS 24
FEET. NEXT WARNINGS AT 180900Z, 181500Z, 182100Z AND 190300Z.//

REMARKS:
180900Z POSITION NEAR 14.5S 83.8E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 808 NM
EAST-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 08 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR) SATELLITE
IMAGERY SHOWS THE SYSTEM HAS BECOME MORE COMPACT AND SYMMETRIC AS IT
DEVELOPED AN OCCLUDED EYE. THE INITIAL POSITION IS BASED ON THE
OCCLUDED EYE IN THE EIR LOOP WITH FAIR CONFIDENCE. THE INITIAL
INTENSITY IS BASED ON THE DVORAK ESTIMATES OF T4.5/77KTS FROM PGTW
AND KNES. UPPER-LEVEL ANALYSIS INDICATES MODERATE RADIAL OUTFLOW WITH
LIGHT TO MODERATE (15-20 KNOT) RELATIVE EASTERLY VERTICAL WIND SHEAR
(VWS). TC 06S IS FORECAST TO TRACK SOUTHWESTWARD THROUGH TAU 48 ALONG
THE NORTHWEST PERIPHERY OF THE SUBTROPICAL RIDGE (STR) TO THE
SOUTHEAST. AFTERWARD, IT WILL TURN MORE WESTWARD AS A SECONDARY STR
TO THE SOUTH ASSUMES STEERING. THIS NEW STR WILL ALSO RECEDE EASTWARD
AND CAUSE THE CYCLONE TO REVERT TO A SOUTHWESTWARD TRACK AFTER TAU
72. TC 06S WILL CONTINUE TO INTENSIFY UNDER THE AFOREMENTIONED
FAVORABLE CONDITIONS THROUGH TAUS 12-24 TO A PEAK OF 80 KNOTS.
AFTERWARD, THE SYSTEM WILL GRADUALLY WEAKEN DUE TO COOLER SST, WEAKER
DIFFLUENCE, AND INCREASING VWS AND, BY TAU 120, TC KENANGA WILL BE
REDUCED TO 40 KNOTS. DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT WITH
SOME SPREADING AFTER TAU 48 TO A SPAN OF OVER 300 NM BY TAU 120. IN
VIEW OF THIS, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK UP
TO TAU 48 AND LOW CONFIDENCE AFTERWARD. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 180600Z IS 25 FEET. NEXT WARNINGS AT 181500Z, 182100Z,

REMARKS:
181500Z POSITION NEAR 15.0S 83.4E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 805 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 06 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
SHOWS THE SYSTEM CONTINUED TO DEEPEN AND HAS BECOME MORE SYMMETRIC
AND ANNULAR AS IT DEVELOPED A DEFINED 40-NM EYE. THE INITIAL POSITION
IS BASED ON THE EYE FEATURE WITH HIGH CONFIDENCE. THE INITIAL
INTENSITY IS BASED ON THE DVORAK ESTIMATES OF T5.0/90KTS FROM PGTW
AND KNES. UPPER-LEVEL ANALYSIS INDICATES A ROBUST RADIAL OUTFLOW WITH
LIGHT TO MODERATE (15-20 KNOT) RELATIVE EASTERLY VERTICAL WIND SHEAR
(VWS). TC 06S WILL CONTINUE TO TRACK SOUTHWESTWARD THROUGH TAU 36
ALONG THE NORTHWEST PERIPHERY OF THE SUBTROPICAL RIDGE (STR) TO THE
SOUTHEAST. AFTERWARD, IT WILL TURN MORE WESTWARD AS A SECONDARY STR
APPROACHING FROM THE SOUTHWEST ASSUMES STEERING. THIS NEW STR WILL
ALSO RECEDE EASTWARD AND ALLOW THE CYCLONE TO REVERT TO A
SOUTHWESTWARD TRACK AFTER TAU 72. CONCURRENTLY, A DEVELOPING CYCLONE
(92S) WILL BE WITHIN PROXIMITY OF TC 06S FOR POSSIBLE BINARY
INTERACTION THAT MAY INTRODUCE A SLOW ERRATIC MOTION. IN THE NEAR
TERM, TC 06S WILL CONTINUE TO INTENSIFY UNDER THE AFOREMENTIONED
FAVORABLE CONDITIONS TO A PEAK OF 95 KNOTS BY TAU 12. AFTERWARD, THE
SYSTEM WILL SLOWLY WEAKEN DUE TO COOLER SST, WEAKER DIFFLUENCE, AND
INCREASING VWS AND, BY TAU 120, TC KENANGA WILL BE REDUCED TO 50
KNOTS. DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT WITH SOME
SPREADING AFTER TAU 48 TO A SPAN OF OVER 180 NM BY TAU 120. IN VIEW
OF THIS, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK UP TO

REMARKS:
182100Z POSITION NEAR 15.5S 83.0E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 799 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 08 KNOTS
(KTS) OVER THE PAST SIX HOURS. THE INITIAL POSITION IS PLACED WITH
HIGH CONFIDENCE USING ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
WHICH SHOWS THE ANNULAR TC HAS A ROUND, 44-NM EYE. THE INITIAL
INTENSITY IS CONSISTENT WITH THE PGTW DVORAK ESTIMATE OF T5.0 (90
KTS). THE ENVIRONMENT IS FAVORABLE WITH RADIAL OUTFLOW, LIGHT (10-15
KT) VERTICAL WIND SHEAR, AND MARGINAL (26-27 CELSIUS) SEA SURFACE
TEMPERATURE. TC 06S IS TRACKING ALONG THE NORTHERN PERIPHERY OF A
GENERALLY EAST-WEST ORIENTED SUBTROPICAL RIDGE (STR). THROUGHOUT THE
FORECAST PERIOD, THE ORIENTATION OF THIS STR WILL DICTATE THE TRACK,
STEERING THE CYCLONE SOUTHWESTWARD THROUGH TAU 36, WESTWARD BETWEEN
TAU 36 AND 72, AND THEN SOUTHWESTWARD AGAIN BETWEEN TAU 72 AND 120.
AROUND THE END OF THE FORECAST PERIOD, ANOTHER CYCLONE (CURRENTLY
92S) MAY APPROACH CLOSE ENOUGH FOR BINARY INTERACTION TO INFLUENCE
THE TRACK. CONSISTENT WITH TYPICAL ANNULAR CYCLONES, THE INTENSITY
SHOULD REMAIN NEARLY CONSTANT FOR THE NEXT 12-24 HOURS BEFORE A SLOW
WEAKENING TREND BEGINS. BY TAU 72, ENVIRONMENTAL CONDITIONS SHOULD
BECOME UNFAVORABLE AND TC 06S SHOULD WEAKEN MORE RAPIDLY. THE MOST
RECENT MODEL GUIDANCE SHOWS A DISTINCT BIFURCATION IN THE GUIDANCE
WITH NAVGEM, GFS, AND THE GFS ENSEMBLE MEAN TURNING LESS SHARPLY
WESTWARD THAN THE OTHER MEMBERS BETWEEN TAU 36 AND 72. THE JTWC
FORECAST TRACK IS HEDGED TOWARDS THE MORE WESTWARD ATTRACTOR WHICH
INCLUDES THE ECMWF, GALWEM, UKMET, AND ECMWF ENSEMBLE MEAN. DESPITE
THE BIFURCATION, THERE IS FAIR CONFIDENCE IN THE JTWC FORECAST
BECAUSE THE SPREAD IS ONLY 250 NM BY TAU 120. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 181800Z IS 27 FEET. NEXT WARNINGS AT 190300Z,
190900Z, 191500Z AND 192100Z.//

REMARKS:
190300Z POSITION NEAR 15.9S 82.6E.
TROPICAL CYCLONE 06S (KENANGA), LOCATED APPROXIMATELY 799 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 06 KNOTS
OVER THE PAST SIX HOURS. THE INITIAL POSITION IS PLACED WITH HIGH
CONFIDENCE BASED ON ANIMATED MULTI-SPECTRAL SATELLITE IMAGERY
DEPICTING A LARGE, 43NM EYE. THE INITIAL INTENSITY WAS INCREASED TO
115 KNOTS BASED ON DVORAK ESTIMATES RANGING FROM T6.0 TO T6.5. NO
RECENT SATCON IS AVAILABLE, HOWEVER, AUTOMATED DVORAK TECHNIQUE ALSO
SUPPORTS THE 115 KNOT ASSESSMENT. FAVORABLE CONDITIONS PERSIST, WITH
ROBUST RADIAL OUTFLOW AND LIGHT (10-15 KNOTS) VERTICAL WIND SHEAR.
HOWEVER, 26-27 DEGREE CELSIUS SEA SURFACE TEMPERATURES ARE MARGINAL.
TC 06S HAS BEEN TRACKING SOUTHWESTWARD UNDER THE STEERING INFLUENCE
OF SUBTROPICAL RIDGING TO THE EAST. THE TRACK IS EXPECTED TO FLATTEN
OUT AND BECOME MORE WESTWARD AROUND TAU 24 AS RIDGING BUILDS IN TO
THE SOUTH OF TRACK. SOUTHWESTERLY MOTION SHOULD RESUME AFTER TAU 72
AS THAT AREA OF RIDGING MOVES EASTWARD. AROUND THE END OF THE
FORECAST PERIOD, CYCLONE 07S MAY APPROACH CLOSE ENOUGH FOR BINARY
INTERACTION TO INFLUENCE THE TRACK. DESPITE OVERALL FAVORABLE
CONDITIONS, KENANGA IS LIKELY AT OR NEAR ITS PEAK INTENSITY AS SST
SUPPORT WEAKENS. BY TAU 72, ENVIRONMENTAL CONDITIONS SHOULD BECOME
UNFAVORABLE AND TC 06S SHOULD WEAKEN MORE RAPIDLY. THE MOST RECENT
MODEL GUIDANCE SHOWS A DISTINCT BIFURCATION IN THE GUIDANCE WITH
NAVGEM, GFS, AND THE GFS ENSEMBLE MEAN TURNING LESS SHARPLY WESTWARD
THAN THE OTHER MEMBERS BETWEEN TAU 36 AND 72. THE JTWC FORECAST TRACK
IS HEDGED TOWARDS THE MORE WESTWARD GROUPING WHICH INCLUDES THE
ECMWF, GALWEM, UKMET, AND ECMWF ENSEMBLE MEAN. THE BI-FURCATION
SCENARIO AND INCREASING POSSIBILITY OF BINARY INTERACTION IS
DECREASING THE JTWC FORECAST CONFIDENCE, NOW ASSESSED AS LOW.

REMARKS:
190900Z POSITION NEAR 16.3S 82.5E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 806 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTH-SOUTHWESTWARD AT 04
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS THE SYSTEM HAS MAINTAINED OVERALL SYMMETRIC AND ANNULAR
CHARACTERISTICS AND A DEFINED EYE, NOW AT 35 NM DIAMETER. THE INITIAL
POSITION IS BASED ON THE EYE FEATURE WITH HIGH CONFIDENCE. THE
INITIAL INTENSITY IS BASED ON AN OVERALL ASSESSMENT OF AGENCY DVORAK
ESTIMATES OF RANGING FROM T5.5 TO T6.5. UPPER-LEVEL ANALYSIS
INDICATES A ROBUST RADIAL OUTFLOW WITH LIGHT TO MODERATE (15-20 KNOT)
RELATIVE EASTERLY VERTICAL WIND SHEAR (VWS). TC 06S WILL CONTINUE TO
TRACK SOUTHWESTWARD THROUGH TAU 24 ALONG THE NORTHWEST PERIPHERY OF
THE SUBTROPICAL RIDGE (STR) TO THE SOUTHEAST. AFTERWARD, IT WILL TURN
MORE WESTWARD AS A SECONDARY STR APPROACHING FROM THE SOUTHWEST
ASSUMES STEERING. THIS NEW STR WILL ALSO RECEDE EASTWARD AND ALLOW
THE CYCLONE TO REVERT TO A SOUTHWESTWARD TRACK AFTER TAU 48.
CONCURRENTLY, ANOTHER CYCLONE (TC 07S) WILL BE WITHIN PROXIMITY OF TC
06S FOR A POSSIBLE BINARY INTERACTION THAT MAY INTRODUCE A SLOW
ERRATIC MOTION. TC 06S APPEARS TO HAVE PEAKED AND WILL NOW SLOWLY
WEAKEN DUE TO COOLER SST, WEAKER DIFFLUENCE, AND INCREASING VWS AND,
BY TAU 120, TC KENANGA WILL BE REDUCED TO 40 KNOTS. DYNAMIC MODEL
GUIDANCE IS IN GOOD AGREEMENT WITH GRADUAL SPREADING TO A SPAN OF 200
NM BY TAU 120 WITH HWRF THE NOTABLE LEFT OF TRACK OUTLIER. IN VIEW OF
THIS, THERE IS FAIR CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 190600Z IS 44 FEET. NEXT WARNINGS AT
191500Z, 192100Z, 200300Z AND 200900Z. REFER TO TROPICAL CYCLONE 07S

REMARKS:
191500Z POSITION NEAR 16.6S 82.1E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 805 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 05 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
SHOWS THE SYSTEM HAS MAINTAINED OVERALL CONVECTIVE STRUCTURE,
ALTHOUGH THERE ARE NOW INDICATIONS OF ELONGATION ALONG THE SOUTHERN
FLANK. TC 06S HAS ALSO MAINTAINED A WELL-DEFINED EYE, NOW AT 25 NM
DIAMETER. THE INITIAL POSITION IS BASED WITH HIGH CONFIDENCE ON THE
EYE FEATURE THAT LINED UP PERFECTLY WITH A MICROWAVE EYE IN THE
191058Z SSMIS. THE INITIAL INTENSITY IS BASED ON AN OVERALL
ASSESSMENT OF AGENCY DVORAK ESTIMATES RANGING FROM T5.5 TO T6.5.
UPPER-LEVEL ANALYSIS INDICATES A ROBUST RADIAL OUTFLOW WITH MODERATE
TO STRONG (20-30 KNOT) EASTERLY VERTICAL WIND SHEAR (VWS). THE
CYCLONE SHOULD NOW TRACK MORE WESTWARD AS A SECONDARY STR APPROACHING
FROM THE SOUTHWEST ASSUMES STEERING. THIS NEW STR WILL ALSO RECEDE
EASTWARD AND ALLOW THE CYCLONE TO REVERT TO A SOUTHWESTWARD TRACK
AFTER TAU 48. CONCURRENTLY, ANOTHER CYCLONE (TC 07S) WILL BE WITHIN
PROXIMITY OF TC 06S FOR A POSSIBLE BINARY INTERACTION THAT MAY
INTRODUCE A SLOW ERRATIC MOTION. TC 06S HAS PEAKED AND WILL NOW
SLOWLY WEAKEN DUE TO COOLER SST, WEAKER DIFFLUENCE, AND INCREASING
VWS AND, BY TAU 120, TC KENANGA WILL BE REDUCED TO 45 KNOTS. DYNAMIC
MODEL GUIDANCE IS IN GOOD AGREEMENT WITH GRADUAL SPREADING TO A SPAN
OF OVER 270 NM BY TAU 120 WITH HWRF THE NOTABLE LEFT OF TRACK
OUTLIER. IN VIEW OF THIS, THERE IS FAIR CONFIDENCE IN THE JTWC
FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 191200Z IS 44
FEET. NEXT WARNINGS AT 192100Z, 200300Z, 200900Z AND 201500Z. REFER
TO TROPICAL CYCLONE 07S (CILIDA) WARNINGS (WTXS32 PGTW) FOR

REMARKS:
192100Z POSITION NEAR 16.5S 81.9E.
TROPICAL CYCLONE 06S (KENANGA), LOCATED APPROXIMATELY 793 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WESTWARD AT 03 KNOTS OVER
THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS A
ROBUST EYEWALL SURROUNDING AN INCREASINGLY RAGGED 13 NM DIAMETER
EYE. THE INITIAL POSITION IS BASED WITH HIGH CONFIDENCE ON THE EYE
FEATURE. THE INITIAL INTENSITY OF 115 KTS IS BASED ON MULTIAGENCY
DVORAK CURRENT INTENSITY ESTIMATES OF T6.0 (115 KTS), AND IS
SLIGHTLY ABOVE A 191514Z SATCON ESTIMATE OF 107 KTS. UPPER-LEVEL
ANALYSIS INDICATES STRONG, WELL-DEFINED POLAR AND EQUATORWARD
OUTFLOW CHANNELS WITH LOW (5-10 KT) VERTICAL WIND SHEAR (VWS). SEA
SURFACE TEMPERATURES ARE MARGINALLY FAVORABLE, AS TC 06S IS
PARALLELING THE 26 DEGREE CELSIUS ISOTHERM TO ITS SOUTH. TC 06S IS
TRACKING DUE WEST ALONG THE NORTHERN PERIPHERY OF A SUBTROPICAL
RIDGE (STR) TO THE SOUTHWEST THAT IS BUILDING INTO THE REGION. AFTER
TAU 48, A MIDLATITUDE TROUGH WILL APPROACH THE REGION, CAUSING THE
STR TO RECEDE EASTWARD AND ALLOWING TC 06S TO TURN TOWARDS THE
SOUTHWEST. CONCURRENTLY, ANOTHER CYCLONE (TC 07S) WILL BE TRACKING
WITHIN PROXIMITY OF TC 06S FOR A POSSIBLE BINARY INTERACTION THAT
MAY INTRODUCE A SLOW ERRATIC MOTION AT LATER TAUS. TC 06S HAS PEAKED
IN INTENSITY AND WILL NOW SLOWLY WEAKEN DUE TO MARGINAL SSTS,
WEAKENING OUTFLOW ALOFT, AND INCREASING VWS. TC 06S IS PREDICTED TO
WEAKEN TO 40 KTS BY TAU 120. DYNAMIC MODEL GUIDANCE IS IN POOR
AGREEMENT, ESPECIALLY AT LATER TAUS, WITH A SPREAD OF 260 NM AT TAU
120. ALL MODELS PORTRAY A TURN TO THE SOUTHWEST, BUT VARY IN THE
SHARPNESS AND DEGREE OF RECURVE. ECMWF IS A NOTABLE OUTLIER NORTH OF
THE MULTI-MODEL CONSENSUS AND BRINGS TC 06S MUCH FURTHER WEST, WHILE
HWRF IS SIGNIFICANTLY SOUTH OF AND FASTER THAN CONSENSUS. THE JTWC
FORECAST TRACK IS POSITIONED CLOSE TO THE MULTI-MODEL CONSENSUS WITH
LOW CONFIDENCE. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 191800Z IS 40

REMARKS:
200900Z POSITION NEAR 16.6S 81.5E.
TROPICAL CYCLONE 06S (KENANGA), LOCATED APPROXIMATELY 785 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WESTWARD AT 02 KNOTS OVER
THE PAST SIX HOURS. THE CURRENT POSITION IS BASED ON A 200329Z ASCAT
PASS WITH HIGH CONFIDENCE. THE INTENSITY OF 100 KNOTS IS CONSISTENT
WITH SUBJECTIVE DVORAK CURRENT INTENSITY ESTIMATES FROM VARIOUS
REPORTING AGENCIES AS WELL AS A RECENT OBJECTIVE SATELLITE INTENSITY
CONSENSUS ESTIMATE OF 99 KNOTS. TC 06S HAS WEAKENED STEADILY OVER THE
PAST SIX HOURS UNDER THE INFLUENCE OF MODERATE VERTICAL WIND SHEAR
AND MARGINAL SEA SURFACE TEMPERATURES, JUST ABOVE 26 DEGREES CELSIUS.
FORWARD MOTION HAS SLOWED AS THE PRIMARY STEERING MECHANISM
TRANSITIONS TO A SUBTROPICAL STEERING RIDGE TO THE SOUTH. TC 06S IS
EXPECTED TO TRACK STEADILY WESTWARD TO SOUTHWESTWARD DURING THE
FORECAST PERIOD AS THE BUILDING SUBTROPICAL RIDGE REMAINS THE PRIMARY
STEERING INFLUENCE. STEADY WEAKENING WILL CONTINUE UNDER ONGOING
INFLUENCE OF MODERATE TO STRONG VERTICAL WIND SHEAR AND PASSAGE OVER
COOLER WATER, WITH DISSIPATION BELOW 35 KNOTS ANTICIPATED BY TAU 120.
NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT REGARDING THIS OVERALL
FORECAST SCENARIO, BUT THERE IS SIGNIFICANT SPREAD IN TERMS OF BOTH
TRACK SPEED AND DIRECTION. THE CURRENT FORECAST TRACK LIES TO THE
WEST OF THE MULTI-MODEL CONSENSUS AND THE PREVIOUS JTWC FORECAST
TRACK, FAVORING THE ECMWF AND UKMET MODEL SOLUTIONS. BOTH OF THESE
MODELS DEPICT STEADY WEAKENING AND A TRACK THAT IS MORE CONSISTENT
WITH THE EXPECTED LOW TO MID-LEVEL FLOW PATTERN. GIVEN THE LARGE
MODEL SPREAD AND UNCERTAINTY REGARDING THE RATE OF EXPECTED
WEAKENING, CONFIDENCE IN THE CURRENT TRACK FORECAST IS LOW. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 200600Z IS 31 FEET. NEXT WARNINGS AT
201500Z, 202100Z, 210300Z AND 210900Z. REFER TO TROPICAL CYCLONE 07S

210300Z POSITION NEAR 16.2S 80.2E.
TROPICAL CYCLONE 06S (KENANGA), LOCATED APPROXIMATELY 716 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-NORTHWESTWARD AT 05
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY DEPICTS A LARGE (200NM DIAMETER) CENTRAL DENSE
OVERCAST REGION. THE INITIAL POSITION IS ASSESSED WITH FAIR
CONFIDENCE BASED ON A 202157Z SSMIS 37 GHZ MICROWAVE EYE FEATURE.
RECENT MICROWAVE IMAGERY REVEALS THAT THE SYSTEM IS TILTING SLIGHTLY
TO THE EAST-SOUTHEAST AND THAT THERE IS SIGNIFICANT EROSION OF
EYEWALL CONVECTION IN THE NORTHWEST QUADRANT DUE TO UPPER LEVEL
CONVERGENCE. THE INITIAL INTENSITY IS ASSESSED AT 80 KNOTS BASED ON
DVORAK CURRENT INTENSITY ESTIMATES RANGING FROM T4.5 TO T5.0 (77 TO
90 KNOTS). TC 06S HAS SLOWED AS THE PRIMARY STEERING MECHANISM HAS
TRANSITIONED TO A SUBTROPICAL STEERING RIDGE TO THE SOUTH. TC 06S IS
EXPECTED TO TRACK STEADILY WESTWARD TO SOUTHWESTWARD DURING THE
FORECAST PERIOD AS THE BUILDING SUBTROPICAL RIDGE REMAINS THE
PRIMARY STEERING INFLUENCE. STEADY WEAKENING IS EXPECTED TO CONTINUE
UNDER THE ONGOING INFLUENCE OF MODERATE TO STRONG VERTICAL WIND
SHEAR AND PASSAGE OVER COOLER WATER, WITH DISSIPATION ANTICIPATED BY
TAU 96. NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT REGARDING THIS
OVERALL FORECAST SCENARIO, BUT THERE IS SIGNIFICANT SPREAD IN TERMS
OF BOTH TRACK SPEED AND DIRECTION. THE CURRENT FORECAST TRACK LIES
TO THE NORTH AND WEST OF THE MULTI-MODEL CONSENSUS, HEDGED BETWEEN
THE ECMWF AND UKMET MODEL SOLUTIONS. BOTH OF THESE MODELS DEPICT
STEADY WEAKENING AND A TRACK THAT IS MORE CONSISTENT WITH THE

210900Z POSITION NEAR 16.2S 79.7E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 701 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-NORTHWESTWARD AT 04
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS RAPIDLY DECAYING DEEP CONVECTION, WHICH IS OBSCURING
THE LOW-LEVEL CIRCULATION. HOWEVER, A 210341Z MHS 89GHZ IMAGE
INDICATES A WEAK MICROWAVE EYE FEATURE AND A PARTIAL EYEWALL WITH
FRAGMENTED BANDING OVER THE SOUTHEAST QUADRANT, WHICH SUPPORTS THE
CURRENT POSITION WITH FAIR CONFIDENCE. THE CURRENT INTENSITY IS
ASSESSED AT 70 KNOTS BASED ON DVORAK INTENSITY ESTIMATES OF 3.5/4.5
(55/77 KNOTS) FROM PGTW AND KNES. TC IS TRACKING SLOWLY UNDER THE
STEERING INFLUENCE OF A SUBTROPICAL RIDGE (STR) POSITIONED TO THE
SOUTH AND IS FORECAST TO GRADUALLY TURN WEST-SOUTHWESTWARD TO
SOUTHWESTWARD AS THE STR RE-ORIENTS TO THE EAST. WITH THE EXCEPTION
OF NAVGEM, WHICH INDICATES A SHARP POLEWARD TURN, THE BULK OF THE
NUMERICAL GUIDANCE IS IN GOOD AGREEMENT WITH A 130NM SPREAD IN

REMARKS:
211500Z POSITION NEAR 16.1S 79.0E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 672 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WESTWARD AT 07 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
DEPICTS RAPIDLY DECAYING DEEP CONVECTION, WHICH IS OBSCURING
THE LOW-LEVEL CIRCULATION. HOWEVER, A 211032Z SSMIS 37GHZ IMAGE
INDICATES A WEAK MICROWAVE EYE FEATURE AND A PARTIAL EYEWALL WITH
CONVECTIVE BANDING OVER THE SOUTHERN SEMICIRCLE, WHICH SUPPORTS THE
CURRENT POSITION WITH FAIR CONFIDENCE. THE CURRENT INTENSITY IS
ASSESSED AT 60 KNOTS BASED ON A PGTW DVORAK CURRENT INTENSITY
ESTIMATE OF 3.5 (55 KNOTS) AND A RECENT SATCON ESTIMATE OF 67 KNOTS.
TC 06S IS TRACKING SLOWLY UNDER THE STEERING INFLUENCE OF A
SUBTROPICAL RIDGE (STR) POSITIONED TO THE SOUTH AND IS FORECAST TO
GRADUALLY TURN WEST-SOUTHWESTWARD TO SOUTHWESTWARD AS THE STR RE-
ORIENTS TO THE EAST. WITH THE EXCEPTION OF NAVGEM, WHICH INDICATES A
SHARP POLEWARD TURN, THE BULK OF THE NUMERICAL GUIDANCE IS IN GOOD
AGREEMENT WITH A 90NM SPREAD IN SOLUTIONS AT TAU 72, THEREFORE,
THERE IS MODERATE CONFIDENCE IN THE JTWC OFFICIAL FORECAST TRACK. TC
KENANGA WILL CONTINUE TO WEAKEN RAPIDLY DUE TO DRY AIR ENTRAINMENT,
UPPER-LEVEL CONVERGENCE AND MARGINALLY FAVORABLE SST VALUES (26C).
THE SYSTEM IS FORECAST TO DISSIPATE BY TAU 72 AS IT TRACKS WITHIN

REMARKS:
212100Z POSITION NEAR 16.3S 78.5E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 659 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WESTWARD AT 06 KNOTS (KTS)
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS CONTINUAL DECAY IN THE CONVECTIVE STRUCTURE BUT THE
LOW LEVEL CIRCULATION CENTER (LLCC) IS BEING OBSCURED BY CIRRUS
CLOUDS. THE INITIAL POSITION IS PLACED WITH FAIR CONFIDENCE BY
EXTRAPOLATING FROM A 211612Z AMSU 89 GHZ MICROWAVE IMAGE WITH A
CORRECTION TO THE WEST-NORTHWEST TO ACCOUNT FOR TILT THAT WAS
EVIDENT IN EARLIER MICROWAVE IMAGES. THE CURRENT INTENSITY IS
ASSESSED AT 55 KTS IS CONSISTENT WITH A PGTW DVORAK CURRENT
INTENSITY ESTIMATE OF 3.5 (55 KTS). TC 06S IS TRACKING ALONG THE
PERIPHERY OF A SUBTROPICAL RIDGE (STR) POSITIONED TO THE SOUTH-
SOUTHEAST AND IS FORECAST TO GRADUALLY TURN WEST-SOUTHWESTWARD TO
SOUTHWESTWARD AS THE STR RE-ORIENTS TO THE EAST. NAVGEM, GFS, AND
THE GFS ENSEMBLE MEAN INDICATE A SHARPER TURN POLEWARD THAN THE JTWC
FORECAST TRACK, WHICH ALIGNS WELL WITH THE REMAINING NUMERICAL
MODELS (ECMWF, UKMET, AND GALWEM). THERE IS MODERATE CONFIDENCE IN
THE JTWC TRACK FORECAST WHICH IS PLACED TO THE LEFT OF THE CONSENSUS
TO ALIGN WITH THE ECMWF, UKMET, AND GALWEM CLUSTER. TC 06S WILL
CONTINUE TO WEAKEN STEADILY DUE TO DRY AIR ENTRAINMENT, UPPER-LEVEL
CONVERGENCE AND MARGINAL (26C-27 CELSIUS) SEA SURFACE TEMPERATURES.
THE SYSTEM IS FORECAST TO DISSIPATE BY TAU 72 AS IT TRACKS INTO THE
NORTHEAST PERIPHERY OF TC 07S. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
211800Z IS 22 FEET. NEXT WARNINGS AT 220300Z, 220900Z, 221500Z AND

220300Z POSITION NEAR 16.6S 78.2E.
TROPICAL CYCLONE (TC) 06S (KENANGA), LOCATED APPROXIMATELY 662 NM
SOUTH-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT
06 KNOTS (KTS) OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS WEAKENING CONVECTIVE STRUCTURE AND AN
OBSCURED LOW LEVEL CIRCULATION CENTER (LLCC). THE INITIAL POSITION
IS PLACED WITH POOR CONFIDENCE BY EXTRAPOLATING FROM A 212012Z AMSR2
36 GHZ MICROWAVE IMAGE WHICH SHOWS A BROAD LLCC. THE CURRENT
INTENSITY IS ASSESSED AT 45 KTS WHICH IS CONSISTENT WITH PGTW AND
KNES DVORAK CURRENT INTENSITY ESTIMATES OF 3.0 (45 KTS). THE
ENVIRONMENT IS UNFAVORABLE, DESPITE LOW (10-15 KT) VERTICAL WIND
SHEAR AND GOOD POLEWARD OUTFLOW, DUE TO MARGINAL (26-27 CELSIUS) SEA
SURFACE TEMPERATURE (SST) AND DRY AIR ENTRAINMENT. TC 06S IS
TRACKING ALONG THE PERIPHERY OF A SUBTROPICAL RIDGE (STR) POSITIONED
TO THE SOUTH-SOUTHEAST. THE CYCLONE IS FORECAST TO GRADUALLY TURN
WEST-SOUTHWESTWARD TO SOUTHWESTWARD AS THE STR RE-ORIENTS TO THE
EAST. TC 06S WILL CONTINUE TO WEAKEN STEADILY DUE TO DRY AIR
ENTRAINMENT AND MARGINAL SSTS UNTIL DISSIPATING BY TAU 48 AS IT
TRACKS TOWARD TC 07S. SPREAD IN THE MODEL GUIDANCE IS 140 NM AT TAU

EXPOSED AND RAGGED LLC. THE INITIAL INTENSITY IS BASED ON THE DVORAK
ESTIMATES OF T2.5/35KTS FROM PGTW AND KNES. TC KENANGA WILL CONTINUE
TO RAPIDLY WEAKEN DUE TO INCREASING VERTICAL WIND SHEAR, COOLING SEA
SURFACE TEMPERATURES, AND INFLUX OF COLD BAROCLINIC AIR. THIS IS THE
FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR
HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 221200Z IS 9 FEET. REFER TO
