Southern Hemisphere Summary

Tropical Cyclone Irving
WTXS21 PGTW 051400
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 11.1S 94.0E TO 13.5S 86.5E
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 051200Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 11.3S 93.9E. THE SYSTEM IS MOVING NORTHWARD AT 01 KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 95S) PREVIOUSLY LOCATED
NEAR 8.8S 94.8E, IS NOW LOCATED NEAR 11.3S 93.9E, APPROXIMATELY 180
NM WEST-NORTHWEST OF COCOS ISLAND. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC)
PARTIALLY COVERED BY FLARING CONVECTION. A 050938Z MHS 89 GHZ IMAGE
AND 050918Z SSMIS 91GHZ IMAGE REVEAL DEEP CONVECTION ONLY IN THE
WESTERN SEMICIRCLE OF THE DISTURBANCE, AND FORMATIVE LOW LEVEL
BANDING WRAPPING INTO THE LLCC. 95S IS LOCATED IN AN AREA OF HIGH
(30-40 KT) VERTICAL WIND SHEAR, WHICH WOULD IMPINGE UPON
DEVELOPMENT. HOWEVER, UPPER LEVEL ANALYSIS DEPICTS AN OTHERWISE
FAVORABLE ENVIRONMENT, WITH MODERATE POLEWARD AND EQUATORWARD
OUTFLOW SUPPORTING DEEP CONVECTION AND WARM SEA SURFACE TEMPERATURES
(28-30 DEGREES CELSIUS). GLOBAL MODELS HAVE CONVERGED OVER THE PAST
SEVERAL RUNS, PREDICTING DEVELOPMENT WITHIN 24 HOURS. WHILE 95S HAS
REMAINED QUASISTATIONARY FOR THE PAST 6 HOURS, IT IS FORECAST TO
TRACK SOUTHWESTWARD IN THE INDIAN OCEAN. 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
061400Z.

REMARKS:
060300Z POSITION NEAR 12.7S 91.0E.
TROPICAL CYCLONE (TC) 04S (IRVING), LOCATED APPROXIMATELY 1173 NM
EAST-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT
09 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A CONSOLIDATING SYSTEM WITH IMPROVED CONVECTIVE
BANDING WRAPPING INTO A DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC).
A 052340Z CORIOLIS 37GHZ IMAGE SHOWS DEEP CONVECTIVE BANDING,
PRIMARILY LOCATED OVER THE WESTERN SEMI-CIRCLE, AND SHALLOW BANDING
OVER THE EASTERN SEMI-CIRCLE WRAPPING INTO A WELL-DEFINED CENTER.
THEREFORE, THERE IS GOOD CONFIDENCE IN THE INITIAL POSITION AND
RECENT TRACK MOTION. THE INITIAL INTENSITY IS ASSESSED AT 35 KNOTS
BASED ON DVORAK INTENSITY ESTIMATES OF T2.5 FROM PGTW AND APRF. TC
04S IS TRACKING WEST-SOUTHWESTWARD ALONG THE NORTHERN PERIPHERY OF
THE SUBTROPICAL RIDGE (STR). AFTER TAU 12, THE SYSTEM SHOULD
GRADUALLY TURN SOUTHWESTWARD AS IT ROUNDS THE STR. TC 04S SHOULD
STEADILY INTENSIFY UNDER FAVORABLE ENVIRONMENTAL CONDITIONS TO A
PEAK OF 70 KNOTS BY TAU 72. AFTER TAU 72, TC 04S WILL RE-CURVE AND
ACCELERATE AS IT BEGINS TO INTERACT WITH THE MIDLATITUDE WESTERLIES,
BEGINNING EXTRA-TROPICAL TRANSITION NEAR TAU 120. DYNAMIC MODEL
GUIDANCE IS IN GOOD AGREEMENT THROUGH TAU 120, THEREFORE, THERE IS
HIGH CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 060000Z IS 9 FEET. NEXT WARNINGS AT 060900Z, 061500Z,
062100Z AND 070300Z. REFER TO TROPICAL CYCLONE 03S (AVA) WARNINGS

REMARKS:
061500Z POSITION NEAR 13.2S 88.5E.
TROPICAL CYCLONE (TC) 04S (IRVING), LOCATED APPROXIMATELY 1050 NM
EAST-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT
13 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS PERSISTENT CONVECTION WHICH NOW SURROUNDS THE LOW
LEVEL CIRCULATION CENTER (LLCC) ASSOCIATED WITH TC 04S. THE INITIAL
POSITION IS BASED ON A 061130Z METEOSAT-8 VISIBLE SATELLITE IMAGE
SHOWING THE AFOREMENTIONED CONVECTION AROUND THE LLCC. THE INITIAL
INTENSITY IS 40 KNOTS WHICH IS HEDGED SLIGHTLY ABOVE DVORAK
ESTIMATES OF T2.5 (35 KNOTS) FROM PGTW AND KNES BASED ON IMPROVING
STORM STRUCTURE. UPPER LEVEL ANALYSIS SHOWS MODERATE TO STRONG
VERTICAL WIND SHEAR VALUES OF 20 TO 25 KNOTS. BOTH POLEWARD AND
EQUATORWARD OUTFLOW CHANNELS ARE CONTINUING TO DEVELOP. SEA SURFACE
TEMPERATURES ARE FAVORABLE FOR DEVELOPMENT (27 TO 28 DEGREES
CELSIUS). TC 04S IS TRACKING WEST-SOUTHWESTWARD ALONG THE NORTHERN
PERIPHERY OF A SUBTROPICAL RIDGE (STR) LOCATED TO THE SOUTH. AFTER
TAU 12, THE SYSTEM WILL GRADUALLY TURN SOUTHWESTWARD AS IT ROUNDS
THE WESTERN EDGE OF THE STR. TC 04S WILL CONTINUE TO INTENSIFY
UNDER FAVORABLE ENVIRONMENTAL CONDITIONS TO A PEAK OF 70 KNOTS BY
TAU 48. AFTER TAU 72, TC 04S WILL BEGIN TO RE-CURVE AND ACCELERATE
AS IT BEGINS TO INTERACT WITH THE MIDLATITUDE WESTERLIES, BEGINNING
EXTRA-TROPICAL TRANSITION NEAR TAU 96. DYNAMIC MODEL GUIDANCE IS IN
GOOD AGREEMENT THROUGH TAU 120, THEREFORE, THERE IS HIGH CONFIDENCE
IN THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
061200Z IS 14 FEET. NEXT WARNINGS AT 062100Z, 070300Z, 070900Z AND
071500Z. REFER TO TROPICAL CYCLONE 03S (AVA) WARNINGS (WTXS31 PGTW)

REMARKS:
070300Z POSITION NEAR 13.8S 86.6E.
TROPICAL CYCLONE (TC) 04S (IRVING), LOCATED APPROXIMATELY 954 NM
EAST-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 11 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS A RAPIDLY CONSOLIDATING SYSTEM WITH A WEAK,
DEVELOPING EYE. A 070021Z SSMIS 91GHZ IMAGE REVEALS TIGHTLY-CURVED
BANDING WRAPPING INTO A WELL-DEFINED MICROWAVE EYE FEATURE, WHICH
SUPPORTS THE INITIAL POSITION WITH GOOD CONFIDENCE. ADDITIONALLY,
THE 37GHZ COLOR COMPOSITE IMAGE SHOWS A CYAN RING, WHICH TYPICALLY
SIGNALS AN IMMINENT RAPID INTENSIFICATION PHASE. THE INITIAL
INTENSITY IS ASSESSED AT 55 KNOTS BASED ON DVORAK INTENSITY
ESTIMATES OF T3.5 FROM PGTW AND FMEE. TC 04S IS TRACKING WEST-
SOUTHWESTWARD TO SOUTHWESTWARD ALONG THE NORTHWESTERN PERIPHERY OF
THE SUBTROPICAL RIDGE (STR), AND IS FORECAST TO CONTINUE TRACKING
SOUTHWESTWARD THROUGH TAU 48. TC 04S SHOULD INTENSIFY RAPIDLY UNDER
FAVORABLE ENVIRONMENTAL CONDITIONS TO A PEAK OF 90 KNOTS BY TAU 36.
AFTER TAU 48, TC 04S WILL RE-CURVE AND ACCELERATE AS IT BEGINS TO
INTERACT WITH THE MIDLATITUDE WESTERLIES, BEGINNING EXTRA-TROPICAL
TRANSITION (ETT) NEAR TAU 72. TC IRVING IS FORECAST TO COMPLETE ETT
BY TAU 96 AS IT BECOMES EMBEDDED WITHIN THE MIDLATITUDE WESTERLIES
AND GAINS FRONTAL CHARACTERISTICS. DYNAMIC MODEL GUIDANCE IS IN GOOD
AGREEMENT THROUGH TAU 96, THEREFORE, THERE IS HIGH CONFIDENCE IN THE
JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 070000Z IS
18 FEET. NEXT WARNINGS AT 070900Z, 071500Z, 072100Z AND 080300Z.

REMARKS:
071500Z POSITION NEAR 14.8S 83.6E.
TROPICAL CYCLONE (TC) 04S (IRVING), LOCATED APPROXIMATELY 825 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT 15
KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY
DEPICTS A RAPIDLY CONSOLIDATING SYSTEM WITH A DEVELOPING EYE. THE
INITIAL POSITION IS BASED ON A 071033Z SSMIS 37 GHZ MICROWAVE
SATELLITE IMAGE WHICH REVEALS THE EYE FEATURE. THE INITIAL INTENSITY
IS ASSESSED AT 75 KNOTS BASED ON A DVORAK INTENSITY ESTIMATE OF T4.5
(77 KNOTS) FROM PGTW. ENVIRONMENTAL ANALYSIS SHOWS MODERATE VERTICAL
WIND SHEAR (15 TO 20 KNOTS) AND DEVELOPING OUTFLOW CHANNELS. SEA
SURFACE TEMPERATURES REMAIN FAVORABLE (27 TO 28 DEGREES CELSIUS). TC
04S IS TRACKING WEST-SOUTHWESTWARD ALONG THE NORTHWESTERN PERIPHERY
OF THE SUBTROPICAL RIDGE (STR), AND IS FORECAST TO CONTINUE TRACKING
WEST-SOUTHWESTWARD THROUGH TAU 72. TC 04S SHOULD CONTINUE TO
INTENSIFY UNDER FAVORABLE ENVIRONMENTAL CONDITIONS TO A PEAK OF 90
KNOTS BY TAU 36 BEFORE BEGINNING TO WEAKEN. AFTER TAU 72, TC 04S WILL
RE-CURVE AND ACCELERATE AS IT BEGINS TO INTERACT WITH THE MIDLATITUDE
WESTERLIES, BEGINNING EXTRA-TROPICAL TRANSITION (ETT) NEAR TAU 72. TC
IRVING IS FORECAST TO COMPLETE ETT BY TAU 96 AS IT BECOMES EMBEDDED
WITHIN THE MIDLATITUDE WESTERLIES AND GAINS FRONTAL CHARACTERISTICS.
DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT THROUGH TAU 96,
THEREFORE, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 071200Z IS 22 FEET. NEXT WARNINGS

REMARKS:
080300Z POSITION NEAR 17.3S 80.7E.
TROPICAL CYCLONE (TC) 04S (IRVING), LOCATED APPROXIMATELY 786 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 19 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS A SLIGHT WEAKENING TREND WITH AN ASYMMETRIC EYEWALL
SURROUNDING A RAGGED 15NM EYE. A 072204Z AMSU-B 89GHZ IMAGE SHOWS A
SLIGHT BREAK IN THE EYEWALL OVER THE NORTH QUADRANT WITH THE BULK OF
THE DEEP CONVECTIVE BANDING LOCATED OVER THE SOUTHERN SEMI-CIRCLE.
THE INITIAL INTENSITY IS ASSESSED AT 90 KNOTS BASED ON DVORAK
INTENSITY ESTIMATES OF T5.0 FROM PGTW AND KNES. TC 04S IS TRACKING
SOUTHWESTWARD ALONG THE NORTHWESTERN PERIPHERY OF THE SUBTROPICAL
RIDGE (STR), AND IS FORECAST TO CONTINUE TRACKING SOUTHWESTWARD
THROUGH TAU 48. TC 04S SHOULD MAINTAIN INTENSITY AT 90 KNOTS THROUGH
TAU 12 DUE TO THE FAVORABLE ENVIRONMENTAL CONDITIONS. AFTER TAU 48,
TC 04S WILL RE-CURVE AND ACCELERATE AS IT BEGINS TO INTERACT WITH
THE MIDLATITUDE WESTERLIES, BEGINNING EXTRA-TROPICAL TRANSITION
(ETT) NEAR TAU 72. TC IRVING IS FORECAST TO COMPLETE ETT BY TAU 96
AS IT BECOMES EMBEDDED WITHIN THE MIDLATITUDE WESTERLIES AND GAINS
FRONTAL CHARACTERISTICS. DYNAMIC MODEL GUIDANCE IS IN VERY GOOD
AGREEMENT THROUGH TAU 96, THEREFORE, THERE IS HIGH CONFIDENCE IN THE
JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 080000Z IS
28 FEET. NEXT WARNINGS AT 080900Z, 081500Z, 082100Z AND 090300Z.

REMARKS:
080900Z POSITION NEAR 18.0S 79.1E.
TROPICAL CYCLONE (TC) 04S (IRVING), LOCATED APPROXIMATELY 761 NM
SOUTH-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD
AT 17 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS DEEP CONVECTION AND AN ORGANIZED SYSTEM WITH A
CLEARLY DEFINED EYE. THE INITIAL POSITION IS BASED ON A 080429Z AMSU
89 GHZ MICROWAVE IMAGE SHOWING THE DEEPEST CONVECTION IS TO THE
SOUTHWEST OF THE LOW LEVEL CIRCULATION CENTER (LLCC). THE INITIAL
INTENSITY OF 90 KNOTS IS BASED ON CURRENT DVORAK INTENSITY ESTIMATES
OF T5.0 (90 KNOTS) FROM BOTH PGTW AND KNES. UPPER LEVEL ANALYSIS
SHOWS MODERATE (15 TO 20 KNOT) VERTICAL WIND SHEAR AND A WELL DEFINED
POLEWARD OUTFLOW CHANNEL. SEA SURFACE TEMPERATURES REMAIN FAVORABLE
(26 TO 27 DEGREES CELSIUS). TC 04S IS TRACKING WEST-SOUTHWESTWARD
ALONG THE NORTHWESTERN PERIPHERY OF THE SUBTROPICAL RIDGE (STR), AND
IS FORECAST TO TRACK SOUTHWESTWARD THROUGH TAU 36. BY TAU 48, TC 04S
WILL RE-CURVE AND ACCELERATE AS IT BEGINS TO INTERACT WITH THE
MIDLATITUDE WESTERLIES AND BEGIN EXTRA-TROPICAL TRANSITION (ETT). TC
IRVING IS FORECAST TO COMPLETE ETT BY TAU 72 AS IT BECOMES EMBEDDED

REMARKS:
081500Z POSITION NEAR 19.0S 77.5E.
TROPICAL CYCLONE (TC) 04S (IRVING), LOCATED APPROXIMATELY 763 NM
SOUTH-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 15
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS DEEP AND PERSISTENT CONVECTION WHICH IS BEGINNING
TO DECREASE IN STRENGTH. THE INITIAL POSITION IS BASED ON A 081043Z
AMSU 89 GHZ MICROWAVE IMAGE SHOWING THE DEEPEST CONVECTION IS TO
THE SOUTHWEST OF THE LOW LEVEL CIRCULATION CENTER (LLCC). THE
INITIAL INTENSITY OF 90 KNOTS IS BASED ON A DVORAK ESTIMATE OF T5.0
(90 KNOTS) FROM KNES AND A 081041Z SATCON ESTIMATE OF 92 KNOTS.
UPPER LEVEL ANALYSIS SHOWS MODERATE (15 TO 20 KNOT) VERTICAL WIND
SHEAR AND A WELL DEFINED POLEWARD OUTFLOW CHANNEL. SEA SURFACE
TEMPERATURES REMAIN FAVORABLE (26 TO 27 DEGREES CELSIUS). TC 04S IS
TRACKING SOUTHWESTWARD ALONG THE NORTHWESTERN PERIPHERY OF THE
SUBTROPICAL RIDGE (STR), AND IS FORECAST TO TRACK SOUTHWESTWARD
THROUGH TAU 36 AND THEN TURN SOUTHWARD. BY TAU 48, TC 04S WILL
BEGIN TO TRACK SOUTHEASTWARD AND ACCELERATE AS IT INTERACTS WITH
THE MIDLATITUDE WESTERLIES AND BEGINS EXTRA-TROPICAL TRANSITION
(ETT). TC IRVING IS FORECAST TO COMPLETE ETT BY TAU 72 AS IT
BECOMES EMBEDDED WITHIN THE MIDLATITUDE WESTERLIES AND GAINS
FRONTAL CHARACTERISTICS. DYNAMIC MODEL GUIDANCE IS IN VERY GOOD
AGREEMENT THROUGH TAU 72, THEREFORE, THERE IS HIGH CONFIDENCE IN
THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 081200Z
IS 26 FEET. NEXT WARNINGS AT 082100Z, 090300Z, 090900Z AND 091500Z.

TROPICAL CYCLONE 04S (IRVING), LOCATED APPROXIMATELY 762 NM
SOUTH-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD
AT 15 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS CENTRALLY LOCATED PERSISTENT DEEP
CONVECTION OCCLUDING A LOW LEVEL CIRCULATION CENTER (LLCC). THE
INITIAL POSITION IS BASED ON A 081604Z METOP-A ASCAT IMAGE SHOWING A
CLEARLY DEFINED LLCC. THE INITIAL INTENSITY OF 90 KNOTS IS BASED ON
DVORAK INTENSITY ESTIMATES OF T5.0 (90 KNOTS) FROM PGTW AND KNES.
THE INITIAL INTENSITY IS ALSO SUPPORTED BY A RECENT SATCON ESTIMATE
OF 91 KNOTS. ENVIRONMENTAL ANALYSIS REVEALS MODERATE (15 TO 20 KNOT)
VERTICAL WIND SHEAR AND WARM SEA SURFACE TEMPERATURES (26 TO 27

REMARKS:
090300Z POSITION NEAR 20.6S 74.3E.
TROPICAL CYCLONE 04S (IRVING), LOCATED APPROXIMATELY 795 NM SOUTH
OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT 19 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
DEPICTS CENTRALLY LOCATED DEEP CONVECTION THAT IS OCCLUDING THE LOW
LEVEL CIRCULATION CENTER (LLCC). THE INITIAL POSITION IS BASED ON A
082157Z 89GHZ AMSU MICROWAVE IMAGE WITH CONVECTIVE BANDING WRAPPING
INTO A CIRCULATION CENTER. THE INITIAL INTENSITY OF 85 KNOTS IS
HEDGED ABOVE A DVORAK INTENSITY ESTIMATE OF T4.5 (77 KNOTS) FROM
PGTW AND IS SUPPORTED BY A RECENT SATCON ESTIMATE OF 83 KNOTS.
ENVIRONMENTAL ANALYSIS DEPICTS A MARGINALLY FAVORABLE ENVIRONMENT
WITH MODERATE (15 TO 20 KNOT) VERTICAL WIND SHEAR BEING OFFSET BY
WARM SEA SURFACE TEMPERATURES (26 TO 27 CELSIUS). UPPER LEVEL
ANALYSIS SHOWS THE SYSTEM HAS A WELL DEFINED POLEWARD OUTFLOW
CHANNEL AND NO ORGANIZED EQUATORWARD OUTFLOW. TC 04S IS TRACKING
SOUTHWESTWARD ALONG THE NORTHWESTERN PERIPHERY OF A SUBTROPICAL
RIDGE (STR) LOCATED TO THE SOUTHEAST. THE SYSTEM IS FORECAST TO
CONTINUE TO TRACK SOUTHEAST THROUGH TAU 36 WHEN IT WILL ROUND THE
RIDGE AXIS. AFTER ROUNDING THE RIDGE AXIS THE SYSTEM WILL RAPIDLY
ACCELERATE TO THE SOUTHEAST AS IT BEGINS TO INTERACT WITH THE MID-
LATITUDE WESTERLIES. AROUND TAU 48, TC IRVING WILL BEGIN THE EXTRA-
TROPICAL TRANSITION (ETT) PROCESS, COMPLETING ETT BY TAU 72. DYNAMIC
MODEL GUIDANCE IS IN STRONG AGREEMENT FOR THE ENTIRE FORECAST PERIOD
LENDING OVERALL HIGH CONFIDENCE IN THE JTWC TRACK FORECAST.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 090000Z IS 27 FEET. NEXT

REMARKS:
092100Z POSITION NEAR 24.7S 70.0E.
TROPICAL CYCLONE 04S (IRVING), LOCATED APPROXIMATELY 769 NM EAST-
SOUTHEAST OF PORT LOUIS, MAURITIU, HAS TRACKED SOUTHWESTWARD AT
20 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY
DEPICTS A PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH
PERSISTENT DEEP CONVECTION IN THE SOUTHERN SEMI-CIRCLE. THE INITIAL
POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON  EXTRAPOLATION FROM
A 091410Z 37 GHZ SSMIS MICROWAVE IMAGE AND 091638Z METOP-B ASCAT
IMAGE. THE AFOREMENTIONED MICROWAVE IMAGE DEPICTS THAT THE DEEP
CONVECTION IS LOCATED IN THE SOUTHERN SEMICIRCLE AND IS SHEARED
SLIGHTLY FROM THE LLCC. THE INITIAL INTENSITY IS ASSESSED AT 65 KNOTS
WHICH IS BASED ON A DVORAK CURRENT INTENSITY ESTIMATE OF T4.0 (65
KNOTS) FROM PGTW AND IS HEDGED BELOW A RECENT SATCON ESTIMATE OF.
ENVIRONMENTAL ANALYSIS REVEALS THAT THE SYSTEM IS IN AN AREA OF
MODERATE TO HIGH (15-20 KNOTS) VERTICAL WIND SHEAR AND IS TRACKING
THROUGH AN AREA OF WARM (26-27 CELSIUS) SEA SURFACE TEMPERATURES.
UPPER LEVEL ANALYSIS SHOWS THAT THE SYSTEM HAS A STRONG POLEWARD
OUTFLOW CHANNEL.TC 04S IS TRACKING WEST-SOUTHWESTWARD ALONG THE
WESTERN EXTENT OF A DEEP-LAYERED SUBTROPICAL RIDGE (STR) LOCATED TO
THE EAST. THE SYSTEM WILL CONTINUE TO TRACK SOUTH-SOUTHWEST THROUGH
TAU 12, AFTER WHICH THE TRACK WILL SHIFT MORE SOUTHERLY AS TC 04S
ROUNDS THE RIDGE AXIS AND BEGINS TO ACCELERATE TO THE SOUTHEAST. THE
SYSTEM HAS BEGUN A WEAKENING TREND DUE TO A MARGINALLY FAVORABLE
ENVIRONMENT. AFTER TAU 24, THE SYSTEM WILL BEGIN TO INTERACT WITH AN
APPROACHING TOUGH WHICH WILL INTRODUCE HIGHER VERTICAL WIND SHEAR
WHICH, COMBINED WITH COOLER SEA SURFACE TEMPERATURES WILL CONTINUE
THE WEAKENING TREND. TC IRVING IS FORECAST TO BEGIN EXTRA TROPICAL
TRANSITION BY TAU 36 AND COMPLETE THE TRANSITION BY TAU 48. DYNAMIC
MODEL GUIDANCE IS IN TIGHT AGREEMENT WITH JGSM BEING THE PRINCIPLE
WESTWARD OUTLIER, SHOWING A SLIGHTLY WIDER TURN TO THE SOUTHEAST THAN
THE REMAINING CONSENSUS MEMBERS. DESPITE THESE TWO OUTLIERS THE
OVERALL AGREEMENT OF THE REMAINING OUTLIERS LENDS HIGH CONFIDENCE IN
THE JTWC TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 091800Z
IS 24 FEET. NEXT WARNINGS AT 100300Z, 100900Z, 101500Z AND 102100Z.

INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE
PARTIALLY EXPOSED LLCC AND A 092302Z 91GHZ SSMIS MICROWAVE IMAGE.
THE AFOREMENTIONED MICROWAVE IMAGE DEPICTS THAT REMAINING CONVECTION
IS LOCATED IN THE SOUTHERN SEMICIRCLE AND IS SHEARED AROUND 100 NM

SLIGHTLY BELOW A DVORAK CURRENT INTENSITY ESTIMATE OF T4.0 (65
KNOTS) FROM PGTW BASED ON THE WEAKENING NATURE OF THE SYSTEM.
ENVIRONMENTAL ANALYSIS REVEALS THAT THE SYSTEM IS IN AN AREA OF
MODERATE TO HIGH (20-25 KNOTS) VERTICAL WIND SHEAR AND IS TRACKING
THROUGH AN AREA OF COOLER (25-26 CELSIUS) SEA SURFACE TEMPERATURES.
UPPER LEVEL ANALYSIS SHOWS THAT THE SYSTEM HAS A STRONG POLEWARD
