MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
200 NM EITHER SIDE OF A LINE FROM 13.2S 78.3E TO 15.8S 71.4E 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 25 TO 30 KNOTS. METSAT IMAGERY AT 221330Z
INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 13.2S 77.1E. THE
SYSTEM IS MOVING WESTWARD AT 19 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 13.8S
79.1E IS NOW LOCATED NEAR 13.2S 77.1E, APPROXIMATELY 445 NM
SOUTHEAST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS A CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC)
WITH IMPROVED CONVECTIVE BANDING WRAPPING INTO THE LLCC. A 220841Z
NOAA-19 89 GHZ IMAGE DEPICTS A CURVED CONVECTIVE BAND OVER THE
NORTHERN SEMI-CIRCLE WRAPPING INTO A MORE DEFINED CENTER. A 220333Z
ASCAT IMAGE SHOWS A DEFINED CIRCULATION WITH 20 TO 25 KNOT WINDS.
SEA SURFACE TEMPERATURE IS FAVORABLE AT 29 TO 30 CELSIUS. UPPER-
LEVEL ANALYSIS DEPICTS A MARGINALLY-FAVORABLE ENVIRONMENT WITH
MODERATE VERTICAL WIND SHEAR OFFSET BY EASTERLY DIFFLUENT FLOW.
DYNAMIC GUIDANCE INDICATES IMPROVING POLEWARD OUTFLOW OVER THE NEXT
COUPLE DAYS, WHICH SHOULD LEAD TO GRADUAL INTENSIFICATION AS THE
SYSTEM TRACKS WEST-SOUTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1002 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

REMARKS:
240900Z POSITION NEAR 16.4S 71.9E.
TROPICAL CYCLONE (TC) 14S (FOURTEEN), LOCATED APPROXIMATELY 546 NM
SOUTH OF DIEGO GARCIA, HAS TRACKED WESTWARD AT 05 KNOTS OVER THE
PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY, ALONG WITH
A 240434Z AMSU-B MICROWAVE PASS, REVEALS A BROAD BUT CONSOLIDATING
LOW LEVEL CIRCULATION CENTER (LLCC) WITH DEEPENING CENTRAL
CONVECTION AND IMPROVED BANDING FEATURES. THE INITIAL POSITION WAS
BASED UPON THIS SATELLITE DATA WITH LOW CONFIDENCE DUE TO THE BROAD
NATURE OF THE LLCC. THE INITIAL INTENSITY OF 35 KNOTS IS BASED UPON
THE CONSOLIDATING STRUCTURE OF THE SYSTEM AND AS DVORAK INTENSITY
ESTIMATES FROM KNES AND FMEE INCREASED TO 35 KNOTS. UPPER LEVEL
ANALYSIS REVEALED AN IMPROVING ENVIRONMENT AS VERTICAL WIND SHEAR
(VWS) HAS DECREASED TO MODERATE LEVELS (15 TO 20 KNOTS) AND OUTFLOW
REMAINS STRONG. TC 14S IS CURRENTLY TRACKING SLOWLY WEST ALONG THE
WESTERN PERIPHERY OF A MODIFYING SUBTROPICAL RIDGE (STR) SITUATED TO
THE EAST OF THE SYSTEM. THIS STR IS EXPECTED TO REMAIN THE DOMINANT
STEERING INFLUENCE THROUGH THE FORECAST PERIOD AS IT MODIFIES AND
TURNS THE CYCLONE TO THE SOUTH-SOUTHWEST THROUGH TAU 72. AFTER TAU
72, THE SYSTEM IS EXPECTED TO TURN MORE TOWARDS THE SOUTH-SOUTHEAST
AS IT ROUNDS THE STR AXIS. TC 14S IS EXPECTED TO GRADUALLY INTENSIFY
THROUGH TAU 72 AS THE SYSTEM CONSOLIDATES AND ENVIRONMENTAL
CONDITIONS OF MARGINAL SEA SURFACE TEMPERATURES (26 TO 27 DEGREES
CELSIUS), MODERATE VWS, AND GOOD OUTFLOW ALLOW. AFTER TAU 72, THE
SYSTEM IS EXPECTED TO BEGIN EXTRA-TROPICAL TRANSITION (ETT) AND
WEAKEN AS IT BEGINS TO TRACK OVER COLD (< 26 DEGREES CELSIUS) SEA
SURFACE TEMPERATURES AND WHILE APPROACHING THE MID-LATITUDE WESTERLY
FLOW. TC 14S IS EXPECTED TO COMPLETE ETT BY TAU 120 AS A STRONG COLD-
CORE LOW. MODEL GUIDANCE IS IN GOOD AGREEMENT WITH THE FORECAST
TRACK ALTHOUGH THERE IS SOME SLIGHT DISAGREEMENT IN WHEN AND WHERE
THE SYSTEM WILL TURN TO THE SOUTH-SOUTHEAST. DUE TO THIS, THE
FORECAST TRACK IS POSITIONED CLOSE TO THE MULTI-MODEL CONSENSUS WITH
OVERALL LOW CONFIDENCE. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 240600Z
IS 10 FEET. NEXT WARNINGS AT 242100Z AND 250900Z. THIS WARNING

INTENSITY OF 55 KNOTS IS HEDGED SLIGHTLY HIGHER THAN THE AVERAGE OF
AGENCY DVORAK ESTIMATES DUE TO THE IMPROVED CONSOLIDATION OF THE
LLCC AND DEEP CONVECTIVE WRAPPING. UPPER LEVEL ANALYSIS INDICATES A
FAVORABLE ENVIRONMENT WITH LOW (5 TO 10 KNOT) VERTICAL WIND SHEAR
(VWS) AND EXCELLENT DUAL CHANNEL OUTFLOW. TC GLENDA IS CURRENTLY
TRACKING WESTWARD UNDER THE INFLUENCE OF A SUB-TROPICAL RIDGE (STR)
TO THE SOUTH. THIS STR WILL REORIENT TO THE EAST OF TC 14S, CAUSING
THE SYSTEM TO TURN POLEWARD, AND REMAIN THE DOMINATE STEERING
MECHANISM THROUGH TAU 72. BEYOND TAU 72, THE CYCLONE WILL ROUND THE
STR RIDGE AXIS AND BEGIN INTERACTING WITH THE MID-LATITUDE
WESTERLIES. UPPER LEVEL ENVIRONMENTAL CONDITIONS WILL REMAIN
FAVORABLE AND SEA SURFACE TEMPERATURES WILL PERSIST ABOVE 27C
ALLOWING TC GLENDA TO STEADILY INTENSIFY AS IT APPROACHES THE STR
AXIS, REACHING A PEAK INTENSITY OF 95 KNOTS BY TAU 48. AFTER TAU 72,
THE CYCLONE WILL BEGIN TO WEAKEN AS VWS INCREASES TO MODERATE LEVELS
(20 TO 30 KNOTS). BEYOND TAU 72, TC 14S WILL BEGIN EXTRA-TROPICAL
TRANSITION (ETT) AS IT EMBEDS IN THE WESTERLY FLOW AND EXPECTED TO
COMPLETE ETT BY THE END OF THE FORECAST PERIOD. DYNAMIC MODEL
GUIDANCE IS IN GOOD AGREEMENT WITH A RE-CURVE SCENARIO LENDING TO
HIGH CONFIDENCE IN THE JTWC FORECAST. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 241800Z IS 14 FEET. NEXT WARNINGS AT 250900Z AND 252100Z.//

REMARKS:
250900Z POSITION NEAR 17.9S 68.8E.
TROPICAL CYCLONE (TC) 14S (GLENDA), LOCATED APPROXIMATELY 661 NM
SOUTH-SOUTHWEST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD
AT 07 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY (MSI) REVEALS A BROAD LOW LEVEL CIRCULATION CENTER
(LLCC) WITH EXPANSIVE DEEP CONVECTIVE BANDING THAT HAS REMAINED
SLIGHTLY BROKEN. A 250414Z AMSU-B MICROWAVE PASS SHOWED THE
CONVECTIVE SIGNATURE OF THE SYSTEM HAS INCREASED IN SIZE WHILE THE
BANDING HAS STARTED TO WRAP TIGHTER IN THE LLCC ALTHOUGH THE CENTRAL
CONVECTION HAS BECOME LIMITED. THE INITIAL POSITION IS BASED ON THE
AFOREMENTIONED MICROWAVE IMAGE AND MSI LOOP WITH GOOD CONFIDENCE.
THE INITIAL INTENSITY OF 55 KNOTS IS BASED ON THE STRUCTURE OF THE
SYSTEM AND DVORAK INTENSITY ESTIMATES OF THE SAME VALUE FROM ALL
REPORTING AGENCIES. ADDITIONALLY, THE WIND FIELD WAS GREATLY
INCREASED BASED ON A 250502Z ASCAT PASS. UPPER LEVEL ANALYSIS
INDICATES A FAVORABLE ENVIRONMENT WITH LOW (05 TO 10 KNOT) VERTICAL
WIND SHEAR (VWS) AND EXCELLENT DUAL CHANNEL OUTFLOW. TC GLENDA IS
CURRENTLY TRACKING WEST-SOUTHWESTWARD UNDER THE INFLUENCE OF A SUB-
TROPICAL RIDGE (STR) TO THE SOUTH. THIS STR IS EXPECTED TO REORIENT
TO THE EAST OF TC 14S OVER THE NEXT 48 HOURS, INDUCING A MORE
SOUTHERLY TRACK. AFTER TAU 48, THE SYSTEM IS EXPECTED TO CREST THE
STR AXIS AND BEGIN TURNING MORE SOUTH-SOUTHEASTERLY. UPPER LEVEL
CONDITIONS WILL REMAIN FAVORABLE AND SEA SURFACE TEMPERATURES WILL
REMAIN ABOVE 27 DEGREES CELSIUS ALLOWING TC GLENDA TO STEADILY
INTENSIFY AS IT APPROACHES THE STR AXIS, REACHING A PEAK INTENSITY
OF 95 KNOTS BY TAU 48. AFTER TAU 72, WEAKENING IS EXPECTED AS THE
SYSTEM APPROACHES THE MID-LATITUDE WESTERLIES WHICH WILL INCREASE
VWS WHILE SEA SURFACE TEMPERATURES BEGIN TO BECOME MARGINAL. AS THE
SYSTEM BECOMES MORE EMBEDDED IN THE MID-LATITUDE FLOW, EXTRA-
TROPICAL TRANSITION (ETT) IS FORECAST TO BEGIN NEAR TAU 72 AND
EXPECTED TO BE COMPLETE BY TAU 120. DYNAMIC MODEL GUIDANCE IS IN
GOOD AGREEMENT WITH A RE-CURVE SCENARIO LENDING TO HIGH CONFIDENCE
IN THE JTWC FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 250600Z IS
17 FEET. NEXT WARNINGS AT 252100Z AND 260900Z.//

REMARKS:
252100Z POSITION NEAR 19.2S 68.0E.
TROPICAL CYCLONE 14S (GLENDA), LOCATED APPROXIMATELY 621 NM EAST
OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTH-SOUTHWESTWARD AT 08
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY SHOWS THE SYSTEM HAS MAINTAINED FLARING AND FRAGMENTED DEEP
CONVECTION, ALBEIT WRAPPED TIGHT INTO THE LOW LEVEL CIRCULATION
CENTER. THE INITIAL POSITION IS BASED ON THE ABOVE ANIMATION AND
EXTRAPOLATED FROM THE 251645Z ASCAT PASS WITH FAIR CONFIDENCE. THE
INITIAL INTENSITY IS BASED ON THE PGTW DVORAK ESTIMATE AND SUPPORTED
BY THE ASCAT DATA. UPPER LEVEL ANALYSIS INDICATES THE CYCLONE IS 06
DEGREES SOUTH OF THE RIDGE AXIS IN AN AREA OF LIGHT TO MODERATE
(10-15 KNOT) VERTICAL WIND SHEAR (VWS) AND GOOD RADIAL OUTFLOW EXCEPT
THE SOUTHWESTERN FLANK. TC 14S IS EXPECTED TO CONTINUE TRACKING ALONG
THE WESTERN PERIPHERY OF A LOW- TO MID-LAYERED SUBTROPICAL RIDGE

260900Z POSITION NEAR 20.7S 67.6E.
TROPICAL CYCLONE (TC) 14S (GLENDA), LOCATED APPROXIMATELY 586 NM
EAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTH-SOUTHWESTWARD AT 07
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) DEPICTS THINNING CONVECTION WITH TIGHTLY-CURVED
BANDING WRAPPING INTO A PARTIALLY-EXPOSED LOW-LEVEL CIRCULATION
CENTER. THE INITIAL POSITION IS BASED ON THE MSI AND SATELLITE FIXES
FROM ALL REPORTING AGENCIES WITH GOOD CONFIDENCE. THE INITIAL
INTENSITY OF 55 KNOTS IS BASED ON AN OVERALL ASSESSMENT OF DVORAK
ESTIMATES FROM PGTW, KNES AND FMEE. UPPER-LEVEL ANALYSIS INDICATES
THE CYCLONE IS NOW LOCATED IN A FAVORABLE ENVIRONMENT WITH LOW (05
TO 10 KNOT) VERTICAL WIND SHEAR (VWS) AND GOOD DUAL CHANNEL OUTFLOW.
TC 14S IS CURRENTLY TRACKING ALONG THE WESTERN PERIPHERY OF A LOW-
TO MID-LAYERED SUBTROPICAL RIDGE (STR) TO THE EAST. ALTHOUGH THE SEA
SURFACE TEMPERATURES AND OCEAN HEAT CONTENT ARE MARGINAL, FAVORABLE
UPPER-LEVEL CONDITIONS ARE EXPECTED TO PERSIST, ALLOWING MODERATE
INTENSIFICATION OVER THE NEXT 36 HOURS. BY TAU 36, TC GLENDA WILL
ROUND THE STR AND RECURVE SOUTHEASTWARD AS THE SYSTEM APPROACHES THE
MID-LATITUDE WESTERLIES.  BY TAU 72, TC 14S WILL BEGIN EXTRA-
TROPICAL TRANSITION (ETT) AS IT EMBEDS IN THE WESTERLY FLOW AND
EXPECTED TO COMPLETE ETT BY THE END OF THE FORECAST PERIOD OR
POSSIBLY SOONER. AVAILABLE NUMERIC GUIDANCE REMAINS IN TIGHT
AGREEMENT, LENDING HIGH CONFIDENCE TO THE JTWC TRACK FORECAST WHICH
IS POSITIONED CLOSE TO MULTI-MODEL CONSENSUS. MAXIMUM SIGNIFICANT

262100Z POSITION NEAR 22.7S 67.1E.
TROPICAL CYCLONE 14S (GLENDA), LOCATED APPROXIMATELY 570 NM EAST-
SOUTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTH-SOUTHWESTWARD
AT 11 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY SHOWS THE CONVECTION HAS WEAKENED AND BECOME
DISPLACED EASTWARD OF THE LOW LEVEL CIRCULATION CENTER. THIS IS
READILY APPARENT ON THE 261402Z SSMIS MICROWAVE PASS. THE INITIAL
POSITION IS BASED ON THE ABOVE IMAGES WITH FAIR CONFIDENCE. THE
INITIAL INTENSITY IS BASED ON CONGRUENT DVORAK ESTIMATES FROM PGTW,
KNES, AND FMEE. UPPER LEVEL ANALYSIS INDICATES THE CYCLONE HAS MOVED
SOUTH OF THE RIDGE AXIS IN AN AREA OF MODERATE TO STRONG (20-30 KNOT)
VERTICAL WIND SHEAR. (VWS). ADDITIONALLY, A MID-LATITUDE TROUGH IS
DIGGING IN FROM THE SOUTHWEST AND CAUSING SUBSIDENCE ALONG THE
WESTERN FLANK OF THE SYSTEM. HOWEVER, STRONG POLEWARD OUTFLOW IS
PROVIDING VENTILATION TO THE WAYWARD CONVECTION. THE CYCLONE HAS
CRESTED THE SUBTROPICAL RIDGE AXIS TO THE EAST AND WILL BEGIN TO
RECURVE SOUTHEASTWARD AFTER TAU 12 INTO THE MID-LATITUDE BAROCLINIC
ZONE. THE INITIAL EXPOSURE INTO THE STRONG WESTERLIES MAY AMPLIFY THE
INTENSITY SLIGHTLY BEFORE GRADUALLY WEAKENING. THE WEAKENING TREND
WILL BE CONCURRENT TO ITS EXTRA-TROPICAL TRANSITION, BECOMING A
GALE-FORCE COLD-CORE LOW BY TAU 72. THE AVAILABLE NUMERIC GUIDANCE
CONTINUES TO BE IN TIGHT AGREEMENT, LENDING HIGH CONFIDENCE TO THE

REMARKS:
272100Z POSITION NEAR 25.7S 67.1E.
TROPICAL CYCLONE (TC) 14S (GLENDA), LOCATED APPROXIMATELY 618 NM 
EAST-SOUTHEAST OF PORT LOUIS, MAURITIUS HAS TRACKED SOUTHWARD AT 06
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR) 
SATELLITE IMAGERY DEPICTS AN EXPANDING AND ELONGATING CLOUD SYSTEM 
STRUCTURE WITH WEAKENED CONVECTION ALONG THE SOUTHERN PERIPHERY OF 
THE SYSTEM. A 271741Z METOP-B MICROWAVE IMAGE REVEALS AN EXPOSED LOW 
LEVEL CIRCULATION CENTER (LLCC) WITH WEAK CONVECTION SHEARED TO THE 
SOUTH OF THE CYCLONE. THE CURRENT POSITION IS BASED ON THE EXPOSED 
LLCC IN EIR AND MICROWAVE IMAGERY WITH GOOD CONFIDENCE. THE CURRENT 
INTENSITY OF 50 KNOTS HAS BEEN INCREASED SLIGHTLY BASED ON A 271649Z 
ASCAT PASS SHOWING 45 TO 50 KNOT WINDS ALONG THE PERIPHERY OF THE 
SYSTEM AS IT GAINS SUPPORT FROM INTERACTION WITH THE MID-LATITUDE 
WESTERLIES. UPPER LEVEL ANALYSIS INDICATES THAT TC 14S HAS STARTED 
TO BE ENVELOPED BY A MID-LATITUDE TROUGH INCREASING VERTICAL WIND 
SHEAR TO 30-40 KNOTS ALONG THE WESTERN AND SOUTHERN PERIPHERIES. TC 
14S CONTINUES TO TRACK POLEWARD ALONG THE WESTERN EDGE OF A 
SUBTROPICAL RIDGE TO THE EAST. BY TAU 12, THE CYCLONE WILL MOVE 
DEEPER INTO A WEAK THICKNESS GRADIENT AND COMMENCE EXTRA-TROPICAL 
TRANSITION (ETT). TC GLENDA IS FORECAST TO COMPLETE ETT AND BECOME A 
GALE-FORCE COLD CORE LOW BY THE END OF THE FORECAST PERIOD. 
AVAILABLE NUMERIC GUIDANCE CONTINUES TO BE IN TIGHT AGREEMENT, 
LENDING TO HIGH CONFIDENCE IN THE JTWC TRACK FORECAST. MAXIMUM 
SIGNIFICANT WAVE HEIGHT AT 271800Z IS 16 FEET. NEXT WARNINGS AT 
280900Z AND 282100Z.//

REMARKS:
280900Z POSITION NEAR 28.2S 67.9E.
TROPICAL CYCLONE (TC) 14S (GLENDA), LOCATED APPROXIMATELY 723 NM
SOUTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTH-
SOUTHEASTWARD AT 14 KNOTS OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY SHOWS THAT TC 14S HAS STARTED TO
LOSE TROPICAL CHARACTERISTICS AS THE REMAINING DEEP CONVECTION HAS
BECOME FURTHER SHEARED TO THE SOUTHEAST OF THE LOW-LEVEL CIRCULATION
CENTER WHICH HAS STARTED TO OPEN AND UNRAVEL. A 290454Z AMSU-B
MICROWAVE ALSO SHOWS THE SYSTEM HAS STARTED TO SLIGHTLY ELONGATE
WHILE DRY AIR IS BEGINNING TO WRAP IN FROM THE WESTERN PERIPHERY.
UPPER LEVEL ANALYSIS REVEALS AN OVERALL UNFAVORABLE ENVIRONMENT AS
THE SYSTEM HAS BECOME FURTHER EMBEDDED INTO THE WESTERLIES WITH
STRONG (30 TO 40 KNOTS) VERTICAL WIND SHEAR WHICH IS COMPLETELY
OFFSETTING THE POLEWARD OUTFLOW. ADDITIONALLY, MARGINAL TO
UNFAVORABLE SEA SURFACE TEMPERATURES SOUTH OF THE CYCLONE ARE NOT
CONDUCIVE FOR TROPICAL SUSTAINMENT. TC GLENDA IS EXPECTED TO TRACK
FURTHER TO THE SOUTH-SOUTHEAST THROUGH THE REMAINDER OF THE FORECAST
WHILE FURTHER LOSING TROPICAL CHARACTERISTICS AND DEVELOPING INTO A
SUBTROPICAL CYCLONE WHICH WILL BE FOLLOWED BY EXTRA-TROPICAL
TRANSITION BEYOND THE FORECAST PERIOD. 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 280600ZIS 16 FEET.//
