REMARKS:
230300Z POSITION NEAR 10.0S 50.3E.
TROPICAL CYCLONE 24S (TWENTYFOUR), LOCATED APPROXIMATELY 716 NM
NORTH-NORTHWEST OF PORT LOUIS, MAURITIUS, HAS TRACKED WEST-
SOUTHWESTWARD AT 05 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY SHOWS RAIN BANDS WRAPPING INTO A LOW
LEVEL CIRCULATION CENTER BECOMING INCREASINGLY MORE COMPACT AND
SYMMETRIC. THE CURRENT POSITION IS BASED ON A BROAD CENTER
IDENTIFIED IN A 221840Z METOP-B ASCAT PASS AND SUPPORTED BY A
222335Z SSMI 85GHZ IMAGE. THE AFOREMENTIONED ASCAT PASS SHOWS A
LARGE SWATH OF 25KT WIND BARBS IN THE WESTERN SEMICIRCLE WITH
LIMITED 30 TO 35 KT BARBS CONFINED TO THE NORTHWEST QUADRANT UNDER
DEEP CONVECTION. THE INTENSITY OF 30 KNOTS IS HEDGED BETWEEN THE
ASCAT DATA AND DVORAK CURRENT INTENSITY ESTIMATES OF T2.5 FROM PGTW
AND KNES. DESPITE THE 30 KNOT INTENSITY ASSESSMENT, THE FIRST
WARNING FOR TC 24S IS BEING ISSUED AS THE SYSTEM IS EXPECTED TO
REACH TROPICAL STORM STATUS WITHIN 24 HOURS. TC 24S IS IN AN
ENVIRONMENT CHARACTERIZED BY LOW (10-15 KNOT) ALONG TRACK SHEAR,
WARM SEA SURFACE TEMPERATURES (28-30 DEGREES CELSIUS) AND A MODERATE
POLEWARD UPPER-LEVEL OUTFLOW CHANNEL. THE SYSTEM IS EXPECTED TO
TRACK WEST-SOUTHWESTWARD ALONG THE PERIPHERY OF A SUBTROPICAL
STEERING RIDGE (STR) TO THE SOUTH, BEFORE MAKING LANDFALL OVER
NORTHERN MOZAMBIQUE. HOWEVER, THERE IS HIGH UNCERTAINTY IN THE
GUIDANCE SOLUTIONS BEYOND TAU 72, DUE TO A 200 NM SPREAD AMONG THE
CONSENSUS. ECMWF AND GFS ARE IN AGREEMENT WITH A WEST-SOUTHWESTWARD
TRACK ALONG THE NORTHERN PERIPHERY OF THE PREVIOUSLY MENTIONED STR
FOLLOWED BY A NORTHWESTERLY TRACK THEREAFTER. UKMET, NAVGEM AND THE
GFS ENSEMBLE TAKE A SLOWER, MORE SOUTHWESTERLY TRACK TO DRAW TC 24S
TOWARDS A TROUGH APROACHING FROM THE SOUTHWEST. THE JTWC TRACK IS
SLIGHTLY EQUATORWARD OF THE CONSENSUS MEAN, FAVORING THE GFS/ECMWF
SOLUTION AND IS EXPECTED TO DISSIPATE OVER MOZAMBIQUE AND TANZANIA
BY TAU 120. THERE IS ALSO SIGNIFICANT UNCERTAINTY IN THE INTENSITY
DUE TO THE POSSIBLE RECURVE SCENARIO BACK ACROSS THE MOZAMBIQUE
CHANNEL. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 230000Z IS 9 FEET. NEXT
WARNINGS AT 230900Z, 231500Z, 232100Z AND 240300Z.

REMARKS:
230900Z POSITION NEAR 10.4S 49.4E.
TROPICAL CYCLONE 24S (TWENTYFOUR), LOCATED APPROXIMATELY 727 NM
NORTHWEST OF PORT LOUIS, MAURITIUS, HAS TRACKED WEST-SOUTHWESTWARD
AT 08 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY SHOWS DEEP CONVECTION BEGINNING TO WRAP
SYMMETRICALLY AROUND A LOW-LEVEL CIRCULATION CENTER AND FORMING THE
EARLY STAGES OF A CENTRAL DENSE OVERCAST. THE CURRENT POSITION IS
PLACED WITH HIGH CONFIDENCE BASED ON A 230545Z METOP-B ASCAT PASS
SHOWING AN AREA OF 35 KNOT WINDS IN THE NORTHWESTERN QUADRANT.
TOGETHER WITH DVORAK ESTIMATES OF T2.5 FROM PGTW AND KNES, THE
INITIAL INTENSITY IS SET AT 35 KNOTS. TC 24S IS CURRENTLY IN A
FAVORABLE ENVIRONMENT WITH LOW VERTICAL WIND SHEAR (5 TO 10 KNOTS),
WARM SEA SURFACE TEMPERATURES (29 TO 30 DEGREES CELSIUS), AND GOOD
EQUATORWARD OUTFLOW. THE SYSTEM IS EXPECTED TO TRACK WEST-
SOUTHWESTWARD AROUND THE PERIPHERY OF A SUBTROPICAL RIDGE TO THE
SOUTH, FOLLOWED BY LANDFALL IN MOZAMBIQUE IN APPROXIMATELY 72 HOURS.
GLOBAL DYNAMICAL MODELS ARE IN GENERALLY GOOD AGREEMENT THROUGH TAU
48, WITH THE ECMWF AND ECMWF ENSEMBLE TO THE RIGHT OF THE CONSENSUS,
THE GFS TOWARD THE CENTER, AND THE NAVGEM BEING THE SOUTHERNMOST
OUTLIER. BEYOND TAU 48 TO 72, THE MODELS DIVERGE SIGNIFICANTLY, WITH
THE ECMWF, GFS, AND THE ECMWF ENSEMBLE TURNING THE SYSTEM TO THE
NORTH AFTER LANDFALL, WHEREAS THE REST OF THE MODELS TURN THE SYSTEM
TO THE SOUTH. THE OFFICIAL JTWC FORECAST IS TO THE RIGHT OF
CONSENSUS AND GENERALLY FOLLOWS THE ECMWF AND GFS TRACK, WITH A
SLOWING OF THE FORWARD MOTION AROUND LANDFALL. GIVEN THE FAVORABLE
ENVIRONMENTAL CONDITIONS ALONG THE PROJECTED TRACK OF TC 24S,
TOGETHER WITH THE CURRENT STATE OF CONVECTIVE ORGANIZATION, THE
INTENSITY FORECAST WAS RAISED SIGNIFICANTLY SINCE THE LAST WARNING.
A PEAK INTENSITY OF 90 KNOTS IS EXPECTED TO BE REACHED BY TAU 48. A
PERIOD OF RAPID INTENSIFICATION IS ALSO LIKELY, SUGGESTING THAT THE
PEAK INTENSITY COULD POTENTIALLY BE EXCEEDED IN THE HOURS PRIOR TO
LANDFALL. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 230600Z IS 9 FEET. NEXT
WARNINGS AT 231500Z, 232100Z, 240300Z AND 240900Z.//

REMARKS:
231500Z POSITION NEAR 10.6S 48.2E.
TROPICAL CYCLONE 24S (KENNETH), LOCATED APPROXIMATELY 703 NM NORTH-
NORTHWEST OF ST DENIS, LA REUNION, HAS TRACKED WEST-SOUTHWESTWARD AT
10 KNOTS (KTS) OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY (MSI) REVEALS THE SYSTEM HAS CONTINUED TO
CONSOLIDATE WITH DEEP CENTRAL CONVECTION, EXCELLENT RADIAL OUTFLOW,
AND AN EXPANDING CENTRAL DENSE OVERCAST. THE INITIAL POSITION IS
BASED ON THE MSI LOOP AND A 231042Z AMSR2 89 GHZ MICROWAVE IMAGE
WITH FAIR CONFIDENCE. THE INITIAL INTENSITY OF 45 KTS IS CONSISTENT
WITH A KNES DVORAK CURRENT INTENSITY ESTIMATE OF T3.0 (45 KTS),
BETWEEN THE PGTW DVORAK CURRENT INTENSITY ESTIMATE OF T2.5 (35 KTS)
AND A 231004Z CIMSS SATCON ESTIMATE OF 51 KTS. THE UPPER-LEVEL
ENVIRONMENT IS VERY FAVORABLE WITH LOW (10-15 KT) VERTICAL WIND
SHEAR (VWS) AND EXCELLENT RADIAL OUTFLOW. SEA SURFACE TEMPERATURE IS
ALSO SUPPORTIVE AT 30 CELSIUS. TC 24S IS TRACKING ALONG THE NORTHERN
PERIPHERY OF A SUBTROPICAL RIDGE (STR). THE STR IS EXPECTED TO
CONTINUE STEERING THE CYCLONE UNTIL MAKING LANDFALL OVER MOZAMBIQUE
SHORTLY AFTER TAU 48. THE FAVORABLE ENVIRONMENT IS EXPECTED TO
SUPPORT RAPID INTENSIFICATION TO 90 KTS BY TAU 36. AFTER TAU 36, IT
APPEARS THAT DIMINISHED OUTFLOW AND SOME DRY AIR ENTRAINMENT SHOULD
CAUSE SOME WEAKENING PRIOR TO MAKING LANDFALL OVER NORTHERN
MOZAMBIQUE. AFTER MAKING LANDFALL, THE RUGGED TOPOGRAPHY IS EXPECTED
TO CAUSE RAPID WEAKENING UNTIL DISSIPATION BY TAU 96. WITH THE
EXCEPTION OF NAVGEM, WHICH IS WELL SOUTH OF THE OTHER MEMBERS,
DYNAMIC MODEL GUIDANCE IS IN FAIRLY GOOD AGREEMENT THROUGH LANDFALL.
AFTER LANDFALL, THE BULK OF THE TRACKERS TURN TC 24S SOUTHWARD
TOWARDS A BREAK IN THE STR AND SLOW THE SYSTEM DOWN BEFORE THEY LOSE
THE CIRCULATION. SOME MEMBERS DO TURN THE REMNANT CIRCULATION BACK
TOWARDS THE MOZAMBIQUE CHANNEL, WHICH SUGGESTS THERE IS A
POSSIBILITY OF REDEVELOPMENT AFTER TAU 96. THE JTWC TRACK FORECAST
IS HEDGED NORTH OF CONSENSUS TO OFFSET THE IMPACT FROM NAVGEM WITH
FAIR CONFIDENCE. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 231200Z IS 11
FEET. NEXT WARNINGS AT 232100Z, 240300Z, 240900Z AND 241500Z. REFER
TO TROPICAL CYCLONE 25S (TWENTYFIVE) WARNINGS (WTXS32 PGTW) FOR SIX-

232100Z POSITION NEAR 10.7S 47.2E.
TROPICAL CYCLONE (TC) 24S (KENNETH), LOCATED APPROXIMATELY 269 NM
EAST-NORTHEAST OF COMOROS ISLAND, HAS TRACKED WESTWARD AT 10 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
SHOWS SIGNIFICANT IMPROVEMENT AS THE SYSTEM BECAME MORE SYMMETRIC AND
CENTRAL CONVECTION DEEPENED. ADDITIONALLY, A WEAK FORMATIVE EYE HAS
BECOME APPARENT. THE INITIAL POSITION IS BASED ON THE FORMATIVE EYE,
LINED UP WITH A MICROWAVE EYE FEATURE IN THE 231541Z GPM 36GHZ
COLORIZED IMAGE WITH HIGH CONFIDENCE. THE INITIAL INTENSITY OF 60
KNOTS IS AVERAGED FROM THE DVORAK ESTIMATES OF T3.5/55KTS AND
T4.0/60KTS FROM PGTW AND KNES, RESPECTIVELY. UPPER LEVEL ANALYSIS
INDICATES THE CYCLONE IS IN AN AREA OF LIGHT TO MODERATE (10-15 KNOT)
EASTERLY VERTICAL WIND SHEAR (VWS) MITIGATED BY THE STORM MOTION IN
PHASE WITH UPPER LEVEL WIND FLOW AND OFFSET BY EXCELLENT RADIAL
OUTFLOW. ADDITIONALLY, ALONG-TRACK SEA SURFACE TEMPERATURES ARE
CONDUCIVE AT 30C. TC 24S IS TRACKING ALONG THE NORTHERN PERIPHERY OF
A SUBTROPICAL RIDGE TO THE SOUTH AND WILL CONTINUE ON A
WEST-SOUTHWESTWARD TRACK FOR THE DURATION OF THE FORECAST, MAKING
LANDFALL OVER NORTHERN MOZAMBIQUE NEAR TAU 48. THE HIGHLY FAVORABLE
ENVIRONMENT WILL PROMOTE RAPID INTENSIFICATION OVER THE NEXT 24 HOURS
PEAKING AT 105 KNOTS BY TAU 24. AFTERWARD, INCREASING VWS AND LAND
INTERACTION, ESPECIALLY AFTER LANDFALL, WILL CAUSE RAPID WEAKENING
AND EVENTUAL DISSIPATION OVER LAND BY TAU 72. NUMERICAL MODEL

(MSI) DEPICTS AN IMPROVING CONVECTIVE SIGNATURE AND EXCELLENT RADIAL
OUTFLOW. IN ADDITION, THE MSI LOOP SUGGESTS AN EYE MAY REVEAL ITSELF
IN THE NEXT FEW HOURS. THE INITIAL POSITION IS PLACED WITH HIGH
CONFIDENCE USING THE MSI LOOP AND BY EXTRAPOLATING FROM AN EYE
FEATURE IN A 240313Z SSMIS 91 GHZ MICROWAVE IMAGE. THE INITIAL
INTENSITY OF 70 KTS IS HEDGED SLIGHTLY ABOVE PGTW/KNES DVORAK
CURRENT INTENSITY ESTIMATES OF T4.0 (65 KTS) BASED ON A 240347Z
CIMSS SATCON ESTIMATE OF 80 KTS. LOW (10-15 KT) VERTICAL WIND SHEAR
(VWS), RADIAL OUTFLOW, AND WARM (29-30 CELSIUS) SEA SURFACE
TEMPERATURES ARE VERY SUPPORTIVE OF CONTINUED INTENSIFICATION. FOR
THE DURATION OF THE FORECAST, TC 24S WILL TRACK ALONG THE NORTHERN
PERIPHERY OF A SUBTROPICAL RIDGE (STR). AN APPROACHING MID-LATITUDE
TROUGH IS EXPECTED TO CREATE A BREAK IN THE STR AS IT DISSIPATES BY
TAU 72. THROUGH TAU 24, THE ENVIRONMENT WILL SUPPORT RAPID

242100Z POSITION NEAR 11.3S 42.8E.
TROPICAL CYCLONE 24S (KENNETH), LOCATED APPROXIMATELY 30 NM
NORTH OF COMOROS ISLAND HAS TRACKED WESTWARD AT 11 KNOTS OVER THE
PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY
REVEALS A NEW EYE AND STRONG CONVECTION IN THE EYEWALL. THE INITIAL
POSITION IS BASED WITH HIGH CONFIDENCE ON THE EYE IN THE EIR
IMAGERY. THE INITIAL INTENSITY OF 100 KTS IS CONSISTENT WITH DVORAK
FIXES OF T5.5 (102 KTS) FROM PGTW AND KNES DUE TO THE EMERGENT EYE.
HOWEVER, IT IS A COMPACT SYSTEM. THE 241800Z OBSERVATION FROM HAHAYA
INTERNATIONAL AIRPORT ON COMOROS ISLAND, 30 NM TO THE SOUTH,
REPORTED WINDS RISING, CURRENTLY AT 36 KTS, AND PRESSURE FALLING,
CURRENTLY AT 1000MB. LOW (10-15 KT) VERTICAL WIND SHEAR, WARM (29-30
CELSIUS) SEA SURFACE TEMPERATURE, AND WELL-DEFINED WESTWARD AND
POLEWARD OUTFLOW ARE VERY SUPPORTIVE OF FURTHER INTENSIFICATION IN
THE NEAR TERM. FOR THE DURATION OF THE FORECAST, TC 24S WILL TRACK
ALONG THE NORTHERN PERIPHERY OF A SUBTROPICAL RIDGE TO THE SOUTH. TC
24S IS EXPECTED TO CONTINUE INTENSIFYING TO 110 KTS IN THE NEXT 12
HOURS UNDER CONTINUED FAVORABLE ENVIRONMENTAL CONDITIONS BEFORE
MAKING LANDFALL AROUND TAU 18. TC 24S WILL WEAKEN RAPIDLY AS IT
MAKES LANDFALL ON THE NORTHERN MOZAMBIQUE COAST. THE CURRENT
FORECAST HAS TC 24S DISSIPATING OVER LAND AFTER TAU 48. HOWEVER, THE
FLAT TERRAIN OF NORTHERN MOZAMBIQUE AND CONTINUED LOW VWS MAY ALLOW
THE CIRCULATION TO REMAIN ORGANIZED OVER LAND. A MIDLATITUDE TROUGH
WILL PASS BY TO THE SOUTH AND CAUSE THE CURRENT DOMINANT STEERING
STR TO RE-ORIENT AND ALLOW ANOTHER STR TO BUILD IN FROM THE
SOUTHWEST, BRINGING LOW-LEVEL SOUTHERLY TO SOUTHEASTERLY FLOW THAT
MAY PUSH THE REMNANTS OF TC 24S BACK OVER WATER AROUND TAU 96-120.
NUMERICAL MODEL GUIDANCE IS IN EXCELLENT AGREEMENT IN THE NEAR TERM,
LENDING HIGH CONFIDENCE TO THE JTWC FORECAST TRACK. GUIDANCE AFTER
THE FORECAST PERIOD DIVERGES SIGNIFICANTLY, WITH SOME MODELS LOOPING
THEN RECURVING TC 24S TO THE NORTHEAST AND RE-EMERGING OVER WATER,
SOME MODELS MOVING TC 24S NORTHWARD BUT REMAINING OVER LAND, AND
UKMET TURNING TC 24S TO THE SOUTH BACK OVER WATER. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 241800Z IS 20 FEET. NEXT WARNINGS AT
250300Z, 250900Z, 251500Z AND 252100Z. REFER TO TROPICAL CYCLONE 25S

IS ASSESSED AT 125 KNOTS BASED ON DVORAK INTENSITY ESTIMATES OF T6.5
(127 KNOTS) FROM BOTH KNES AND PGTW. UPPER-LEVEL ANALYSIS INDICATES
A FAVORABLE ENVIRONMENT WITH LOW TO MODERATE VERTICAL WIND SHEAR AND
RADIAL OUTFLOW ENHANCED BY STRONG WESTERLIES TO THE SOUTH. TC 24S IS
FORECAST TO TRACK WEST-SOUTHWESTWARD ALONG THE NORTHERN PERIPHERY OF
THE SUBTROPICAL RIDGE (STR) THROUGH TAU 24 WITH LANDFALL EXPECTED
NEAR TAU 12. TC 24S IS FORECAST TO GRADUALLY WEAKEN AS IT APPROACHES

TROPICAL CYCLONE 24S (KENNETH), LOCATED APPROXIMATELY 594 NM
NORTH OF EUROPA ISLAND, HAS TRACKED WEST-SOUTHWESTWARD AT 07
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY DEPICTS A DRASTIC WEAKENING, WARMING, AND
SHRINKING OF THE CENTRAL CONVECTION OF TC 24S. THE INITIAL POSITION
IS BASED WITH FAIR CONFIDENCE ON TURNING IN THE EIR LOOP, WHICH IS
OBSCURING THE LOW LEVEL CIRCULATION CENTER (LLCC), AND A 251557Z
SSMIS 91GHZ MICROWAVE IMAGE WHICH REVEALS A SMALL BALL OF REMAINING
DEEP CONVECTION THAT IS OVER LAND. THE CURRENT INTENSITY IS ASSESSED
AT 75 KNOTS WITH LOW CONFIDENCE BASED ON THE RAPID DISSOLUTION OF
CONVECTION AND STRUCTURE OVER LAND. UPPER-LEVEL ANALYSIS INDICATES A
FAVORABLE ATMOSPHERIC ENVIRONMENT WITH LOW TO MODERATE VERTICAL WIND
SHEAR, WITH MODERATE BUT WEAKENING DIVERGENCE ALOFT. HOWEVER, LAND
INTERACTION WILL DOMINATE AND QUICKLY WEAKEN TC 24S. TC 24S IS
FORECAST TO MOVE WEST-SOUTHWESTWARD AND SLOW DOWN ALONG THE NORTHERN
PERIPHERY OF THE SUBTROPICAL RIDGE (STR) TO ITS SOUTH THROUGH TAU
24. AFTER TAU 24, THE STR IS FORECAST TO ERODE AS A SHORTWAVE TROUGH
DEEPENS TO THE SOUTH, WHICH WILL RESULT IN A SLOW SOUTHWESTWARD TO
SOUTHWARD DRIFT WHILE STILL OVER LAND. THERE IS A SLIGHT POSSIBILITY
THAT THE SYSTEM MAY TRACK BACK OVER WATER AFTER TAU 72, HOWEVER, THE
SYSTEM IS EXPECTED TO HAVE WEAKENED SIGNIFICANTLY BY THAT TIME, AND
MODEL SOLUTIONS HAVE BEEN WALKING TOWARDS THE WEST, FAVORING THE
REMNANTS OF TC 24S STAYING OVER LAND FOR LONGER. OVERALL, THERE IS
LOW CONFIDENCE IN THE JTWC FORECAST TRACK DUE TO THE WEAK STEERING
ENVIRONMENT AND POTENTIAL FOR QUASI-STATIONARY MOTION AFTER TAU 24
AS REFLECTED IN THE LARGE SPREAD OF DYNAMIC MODEL GUIDANCE AFTER TAU
24. 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. REFER TO TROPICAL CYCLONE 25S (LORNA)
