MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
REF/A/JOINT TYPHOON WRNCEN PEARL HARBOR HI/051951Z APR 15//
AMPN/REF IS TROPICAL CYCLONE FORMATION ALERT (WTXS22 PGTW 052000)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
115 NM EITHER SIDE OF A LINE FROM 15.2S 64.5E TO 13.7S 61.0E
WITHIN THE NEXT 06 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 28 TO 34 KNOTS. METSAT
IMAGERY AT 052000Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 14.9S 63.8E. THE SYSTEM IS MOVING WEST-NORTHWESTWARD AT 10
KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 15.3S
64.7E IS NOW LOCATED NEAR 14.9S 63.8E, APPROXIMATELY 600 NM
NORTHEAST OF LA REUNION. RECENT ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY DEPICTS AN AREA OF PULSING DEEP CONVECTION
ASSOCIATED WITH A WELL DEFINED LOW LEVEL CIRCULATION CENTER (LLCC).
A 051513Z SSMIS MICROWAVE IMAGE REVEALS DEEP CONVECTIVE BANDS
BEGINNING TO FORM AND CURVE INTO THE CONSOLIDATING SYSTEM CENTER.
UPPER LEVEL ANALYSIS INDICATES A MARGINAL TO FAVORABLE ENVIRONMENT
CHARACTERIZED BY MODERATE (15-25 KTS) VERTICAL WIND SHEAR (VWS) AND
STRONG RADIAL OUTFLOW. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 28-34 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
1000 MB. DUE TO THE INCREASED CONSOLIDATION OF THE LLCC, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS HIGH. ALERT WILL BE REISSUED, UPGRADED
TO WARNING OR CANCELLED BY 062100Z.//

REMARKS:
060300Z POSITION NEAR 14.6S 62.7E.
TROPICAL CYCLONE (TC) 22S (TWENTYTWO), LOCATED APPROXIMATELY 460 NM
NORTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED WEST-NORTHWESTWARD
AT 08 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY SHOWS THE SYSTEM HAS FURTHER CONSOLIDATED EVEN AS
THE BULK OF DEEP CONVECTION REMAINS SLIGHTLY SHEARED NORTHEASTWARD.
THE INITIAL POSITION IS BASED ON A BROAD LOW LEVEL CIRCULATION CENTER
EVIDENT ON THE 052208Z AMSU-B MICROWAVE PASS WITH FAIR CONFIDENCE.
THE INITIAL INTENSITY IS BASED ON AN OVERALL ASSESSMENT OF AGENCY
DVORAK ESTIMATES. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS 10
DEGREES EAST OF AN ANTICYCLONE IN AN AREA OF MODERATE (15-20 KNOT)
VERTICAL WIND SHEAR (VWS). HOWEVER, THE VWS IS EASILY OFFSET BY
EXCELLENT RADIAL OUTFLOW THAT IS PROVIDING VENTILATION TO THE
ASSOCIATED CONVECTION. TC 22S IS SLOWLY TRACKING ALONG THE NORTHERN
PERIPHERY OF A LOW-LEVEL REFLECTION OF THE SUBTROPICAL RIDGE (STR) TO
THE SOUTH. AFTER TAU 36, A MID-LATITUDE TROUGH WILL WEAKEN THE STR.
CONCURRENTLY, A BUILDING NEAR-EQUATORIAL RIDGE (NER) TO THE NORTH
WILL INFLUENCE THE STORM MOTION OF THE SYSTEM, RENDERING 22S IN A
QUASI-STATIONARY SITUATION. AFTER TAU 48, THE NER WILL EMERGE AS THE
DOMINANT STEERING MECHANISM AND DRIVE THE CYCLONE SOUTHEASTWARD. AS
TC 22S TRANSITIONS BETWEEN TWO DRIVING FORCES, THE VWS IS EXPECTED TO
WEAKEN. THIS WILL ALLOW THE SYSTEM TO INTENSIFY, PEAKING AT 100 KNOTS
BY TAU 96, AFTER ITS EXPOSURE TO THE STRONG MID-LATITUDE WESTERLIES.
AFTERWARDS, THE VWS WILL ONCE AGAIN INCREASE, CAUSING GRADUAL
WEAKENING OF THE CYCLONE. THE INITIAL SET OF NUMERIC GUIDANCE IS IN
UNUSUALLY GOOD AGREEMENT, TENTATIVELY LENDING HIGH CONFIDENCE TO THE
JTWC TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 060000Z IS 10
FEET. NEXT WARNINGS AT 061500Z AND 070300Z. REFER TO TROPICAL CYCLONE
21S (TWENTYONE) WARNINGS (WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES.//

REMARKS:
061500Z POSITION NEAR 14.9S 61.4E.
TROPICAL CYCLONE 22S (TWENTYTWO), LOCATED APPROXIMATELY 401 NM
NORTHEAST OF PORT LOUIS, MAURITIU, HAS TRACKED WEST-SOUTHWESTWARD
AT 09 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY SHOWS THE DEEPENING SYSTEM WITH SOME SPIRALED
BANDING WRAPPING INTO A PARTIALLY EXPOSED LOW LEVEL CIRCULATION
CENTER (LLCC) SOUTHWEST OF THE DEEP CONVECTION. THIS IS REAFFIRMED
BY A 061107Z SSMI MICROWAVE IMAGE WITH GOOD CONFIDENCE. THE
INTENSITY IS MAINTAINED AT 45 KNOTS AS DVORAK INTENSITY ESTIMATES
HAVE BEEN FAIRLY CONSISTENT ACROSS ALL REPORTING AGENCIES. UPPER-
LEVEL ANALYSIS SHOWS DEVELOPING DUAL OUTFLOW CHANNELS NEGATING THE
EFFECTS OF THE MODERATE (10 TO 20 KNOT) VERTICAL WIND SHEAR (VWS).
THE CYCLONE IS TRACKING ALONG THE NORTHERN PERIPHERY OF A
SUBTROPICAL RIDGE (STR) FOR THE NEXT 24 HOURS. AS THE STR WEAKENS
AND TRACKS TO THE EAST, THE MAIN STEERING INFLUENCE WILL SHIFT TO A
BUILDING NEAR EQUATORIAL RIDGE NORTH OF  TC 22S, FORCING A POLEWARD
TURN OF THE SYSTEM. AS TC 22S BEGINS TO TRACK TO THE SOUTH, EXPECT
INTENSIFICATION AS A DEEP UPPER-LEVEL TROUGH PROVIDES EXCELLENT
OUTFLOW, PEAKING TC 22SS INTENSITY TO 90 KNOTS BY TAU 72. THERE
WILL BE SLIGHT DECAY OF THE SYSTEM AS IT CONTINUES TO TRACK POLEWARD
UNDER THE INFLUENCE OF A STR BUILDING TO THE EAST OF THE SYSTEM. AS
VWS INCREASES AND OCEAN HEAT CONTENT BEGINS TO WANE, EXPECT SOME
DECAY IN THE SYSTEM THROUGH THE REMAINDER OF THE FORECAST. THERE IS
SOME DISPARITY IN DYNAMIC MODEL GUIDANCE PAST TAU 36 DUE TO THE
SHIFT IN THE STEERING ENVIRONMENT. THIS LEADS TO AN OVERALL LOW
CONFIDENCE IN THE JTWC FORECAST TRACK WHICH IS CLOSE TO THE MULTI-
MODEL CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 061200Z IS 14
FEET. NEXT WARNINGS AT 070300Z AND 071500Z. REFER TO TROPICAL
CYCLONE 21S (IKOLA) WARNINGS (WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES.

REMARKS:
070300Z POSITION NEAR 13.7S 62.3E.
TROPICAL CYCLONE (TC) 22S (JOALANE), LOCATED APPROXIMATELY 484 NM
NORTHEAST OF PORT LOUIS, MAURITIUS HAS TRACKED NORTHEASTWARD AT
07 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS A BROAD AND ELONGATED CENTRAL CORE WITH
DEEP SPIRAL BANDING WRAPPING INTO THE WESTERN PERIPHERY. A 062217Z
SSMI 37GHZ MICROWAVE IMAGE SHOWS A DEEPENING CENTRAL CORE THAT IS
WRAPPING AROUND A WELL-DEFINED MICROWAVE EYE FEATURE, LENDING HIGH
CONFIDENCE TO THE INITIAL POSITION. THE INITIAL INTENSITY IS HELD AT
45 KNOTS BASED ON A CONSENSUS OF DVORAK INTENSITY ESTIMATES OF T3.0
(45 KNOTS) FROM ALL AGENCIES AND SUPPORTED BY A SCATTEROMETER PASS
FROM 061800Z SHOWING 45 KNOT WINDS ALONG THE EASTERN PERIPHERY.
UPPER LEVEL ANALYSIS INDICATES A FAVORABLE ENVIRONMENT WITH LOW (5-
10 KNOT) VERTICAL WIND SHEAR (VWS) AND GOOD EQUATORWARD OUTFLOW;
HOWEVER, LOW OCEAN HEAT CONTENT IN THE REGION OF THE QUASI-
STATIONARY MOTION IS PREVENTING CURRENT INTENSIFICATION. TC 22S IS
CURRENTLY IN A COMPETING STEERING ENVIRONMENT AS THE SUB-TROPICAL
RIDGE TO THE SOUTH WEAKENS DUE TO A PASSING SHORTWAVE TROUGH AND THE
NEAR-EQUATORIAL RIDGE (NER) TO THE NORTHEAST ASSUMES STEERING. AS
THE NER TAKES OVER STEERING, TC JOALANE WILL TRACK POLEWARD THROUGH
TAU 96. EXPECT THE SYSTEM TO INTENSIFY THROUGH TAU 72 AS UPPER LEVEL
CONDITIONS REMAIN FAVORABLE. ADDITIONALLY, AN ENHANCED POLEWARD
OUTFLOW CHANNEL WILL DEVELOP NEAR TAU 36 DUE TO ANOTHER MID-LATITUDE
SHORTWAVE TROUGH PASSING TO THE SOUTH. BEYOND TAU 72, THE SYSTEM
WILL BEGIN TO WEAKEN SLIGHTLY AS THE AFOREMENTIONED SHORTWAVE TROUGH
MOVES DOWNSTREAM AND THE DIVERGENCE ALOFT WEAKENS. IN ADDITION, VWS
WILL INCREASE TO MODERATE LEVELS AND SEA SURFACE TEMPERATURES DROP
BELOW 27 CELSIUS. THE MOVEMENT OF THE SHORTWAVE TROUGH WILL ALSO
ALLOW AN EXTENSION OF THE SUB-TROPICAL RIDGE TO BUILD IN TO THE
SOUTHEAST, FORCING TC 22S TO TURN SLIGHTLY WESTWARD BY THE END OF
THE FORECAST PERIOD. DUE TO THE DYNAMIC STEERING ENVIRONMENT, THERE
IS A LARGE SPREAD IN THE DYNAMIC MODEL TRACK AND SPEED GUIDANCE. IN
LIEU OF THIS, THERE IS LOW CONFIDENCE IN THE JTWC FORECAST. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 070000Z IS 16 FEET. NEXT WARNINGS AT
071500Z AND 080300Z. REFER TO TROPICAL CYCLONE 21S (IKOLA) WARNINGS

REMARKS:
071500Z POSITION NEAR 14.5S 62.9E.
TROPICAL CYCLONE (TC) 22S (JOALANE), LOCATED APPROXIMATELY 469 NM
NORTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTH-SOUTHEASTWARD
AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY (MSI) DEPICTS THE SYSTEM HAS RAPIDLY CONSOLIDATED
WITH DEEPENED CONVECTION AND SPIRAL BANDS WRAPPING INTO A LARGE 35
NM EYE.  A 071052Z SSMI MICROWAVE IMAGE REVEALS INCREASED CONVECTIVE
BANDING WRAPPING INTO AN APPARENT MICROWAVE EYE. THE CURRENT
POSITION IS BASED ON THE EYE FEATURE ON THE MSI AND SATELLITE FIXES
FROM ALL REPORTING AGENCIES WITH GOOD CONFIDENCE. THE INITIAL
INTENSITY HAS INCREASED TO 80 KNOTS BASED ON AN OVERALL ASSESSMENT
OF THE CURRENT STRUCTURE AND DVORAK INTENSITY ESTIMATES FROM PGTW
AND KNES. DUE TO RAPID INTENSIFICATION, THERE IS A 35 KNOT INCREASE
OVER THE PAST TWELVE HOURS. UPPER LEVEL ANALYSIS INDICATES A VERY
FAVORABLE ENVIRONMENT WITH LOW (05 TO 10 KNOT) VERTICAL WIND SHEAR
(VWS) AND EXCELLENT DUAL OUTFLOW CHANNELS. TC 22S IS TRACKING UNDER
THE STEERING INFLUENCE OF THE NEAR-EQUATORIAL RIDGE (NER) TO THE
NORTHEAST. UPPER-LEVEL CONDITIONS ARE EXPECTED TO PERSIST ALLOWING
TC JOALANE TO FURTHER INTENSITY TO A PEAK INTENSITY OF 140 KNOT BY
TAU 48. AFTERWARDS, INCREASING VWS WILL SLOWLY WEAKEN THE SYSTEM AS
IT CONTINUES TO TRACK POLEWARD. AVAILABLE MODEL GUIDANCE IS IN GOOD
AGREEMENT, LENDING HIGH CONFIDENCE IN THE JTWC TRACK; HOWEVER, DUE
TO UNCERTAINTY IN THE INTENSITY FORECAST IN THE NEAR TERM, OVERALL
JTWC FORECAST CONFIDENCE LEVEL REMAINS LOW. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 071200Z IS 22 FEET. NEXT WARNINGS AT 080300Z AND 081500Z.

REMARKS:
080300Z POSITION NEAR 14.9S 63.3E.
TROPICAL CYCLONE (TC) 22S (JOALANE), LOCATED APPROXIMATELY 468 NM
NORTHEAST OF PORT LOUIS, MAURITIUS HAS TRACKED SOUTHEASTWARD AT
03 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY SHOWS THAT THE EYE FEATURE HAS BECOME EXPOSED
ALONG THE SOUTHERN PERIPHERY; HOWEVER, DEEP CONVECTIVE SPIRAL
BANDING CONTINUES TO WRAP INTO THE CLOUD SYSTEM CENTER. THE WATER
VAPOR LOOP DEPICTS A STRUGGLING CONVECTIVE CORE AS DRY AIR FROM THE
WEST IS BEING PULLED INTO THE CIRCULATION. A 080008Z 91GHZ SSMIS
MICROWAVE IMAGE CONTINUES TO DEPICT A WELL DEFINED MICROWAVE EYE
SURROUNDED BY DEEP CONVECTIVE BANDING. THE INITIAL POSITION IS BASED
ON THE MICROWAVE EYE FEATURE AND THE EIR LOOP WITH GOOD CONFIDENCE.
THE INITIAL INTENSITY OF 90 KNOTS IS BASED ON CONCURRING AGENCY
CURRENT INTENSITY ESTIMATES OF T5.0 (90 KNOTS) FROM PGTW, KNES, AND
FMEE. UPPER LEVEL ANALYSIS REVEALS A POINT SOURCE HAS DEVELOPED OVER
THE SYSTEM PROVIDING RADIAL OUTFLOW. IN ADDITION, LOW (05 TO 10
KNOT) VERTICAL WIND SHEAR (VWS) AND SEA SURFACE TEMPERATURES ABOVE
28 CELSIUS WILL SUPPORT GRADUAL INTENSIFICATION. TC 22S IS TRACKING
UNDER THE STEERING INFLUENCE OF THE NEAR-EQUATORIAL RIDGE (NER) TO
THE NORTHEAST. THE SYSTEM WILL TRANSITION TO A BUILDING SUB-TROPICAL
RIDGE TO THE EAST NEAR TAU 72, WHICH WILL TURN THE TRACK SLIGHTLY
MORE POLEWARD. TC JOALANE WILL STEADILY INTENSIFY OVER THE NEXT 36
HOURS AS MOST ENVIRONMENTAL CONDITIONS REMAIN FAVORABLE; HOWEVER,
THE SYSTEM WILL CONTINUE TO FIGHT DRY AIR ENTRAINMENT. BEYOND TAU
36, TC 22S WILL BEGIN TO ENCOUNTER MODERATE (20-25 KNOT) VWS AND
REDUCED SEA SURFACE TEMPERATURES (SSTS) BEGINNING ITS WEAKENING
TREND. THE SYSTEM WILL FURTHER WEAKEN AND BEGIN SUB-TROPICAL
TRANSITION BY THE END OF THE FORECAST PERIOD AS SSTS DROP BELOW 26
CELSIUS AND THE SYSTEM GETS EMBEDDED IN THE WESTERLY FLOW WHERE IT
WILL BEGIN ADVECTING COOLER TEMPERATURES. DYNAMIC MODEL GUIDANCE
CONTINUES TO IMPROVE, LENDING HIGH CONFIDENCE IN THE JTWC TRACK
FORECAST; HOWEVER, DUE TO UNCERTAINTY IN THE INTENSITY FORECAST IN
THE NEAR TERM, OVERALL JTWC FORECAST CONFIDENCE REMAINS LOW. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 080000Z IS 26 FEET. NEXT WARNINGS AT
081500Z AND 090300Z. REFER TO TROPICAL CYCLONE 21S (IKOLA) WARNINGS

081500Z POSITION NEAR 15.6S 64.9E.
TROPICAL CYCLONE 22S (JOALANE), LOCATED APPROXIMATELY 624 NM
EAST-NORTHEAST OF ST DENIS, HAS TRACKED SOUTHEASTWARD AT 09 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
(MSI) DEPICTS IMPROVED DEEP CONVECTION WITH SPIRAL BANDS WRAPPING
INTO A 20 NM EYE. A 081036Z SSMI MICROWAVE IMAGE REVEALS TIGHTLY
CURVED BANDING SURROUNDING A WELL-DEFINED MICROWAVE EYE. THE INITIAL
POSITION IS BASED ON THE EYE FEATURE ON THE MSI WITH HIGH
CONFIDENCE. THE INITIAL INTENSITY REMAINS AT 90 KNOTS BASED ON AN
OVERALL ASSESSMENT OF THE IMPROVED STRUCTURE AND DVORAK INTENSITY
ESTIMATES FROM PGTW AND KNES. UPPER-LEVEL ANALYSIS INDICATES A POINT
SOURCE DIRECTLY OVER THE SYSTEM SUPPORTING THE DEEPENED CONVECTION
AND PROVIDING RADIAL OUTFLOW. TC 22S IS CURRENTLY TRACKING UNDER THE
STEERING INFLUENCE OF THE NEAR-EQUATORIAL RIDGE TO THE NORTHEAST.
THE SYSTEM WILL TRANSITION TO A BUILDING SUB-TROPICAL RIDGE TO THE
EAST AFTER TAU 48 AND WILL REMAIN ON A SOUTH-SOUTHEASTWARD
TRAJECTORY. TC JOALANE WILL STEADILY INTENSIFY OVER THE NEXT 36
HOURS AS FAVORABLE UPPER-LEVEL CONDITIONS PERSIST. BEYOND TAU
36, TC 22S IS FORECAST TO ENCOUNTER MODERATE (20 TO 25 KNOT)
VERTICAL WIND SHEAR AND REDUCED SEA SURFACE TEMPERATURES LEADING TO
ITS WEAKENING TREND. BY TAU 96, THE SYSTEM WILL BEGIN TO INTERACT
WITH THE MID-LATITUDE WESTERLIES AND IS EXPECTED TO COMPLETE EXTRA-
TROPICAL TRANSITION BY THE END OF THE FORECAST PERIOD. AVAILABLE
MODEL GUIDANCE REMAINS IN GOOD AGREEMENT LENDING HIGH CONFIDENCE IN
THE JTWC TRACK FORECAST; HOWEVER, DUE TO UNCERTAINTY IN THE
INTENSITY FORECAST IN NEAR TERM, OVERALL JTWC FORECAST CONFIDENCE
LEVEL REMAINS LOW. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 081200Z IS 28

REMARKS:
090300Z POSITION NEAR 16.5S 65.4E.
TROPICAL CYCLONE (TC) 22S (JOALANE), LOCATED APPROXIMATELY 513 NM
EAST-NORTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTH-SOUTHEAST-
WARD AT 05 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
(EIR) SATELLITE IMAGERY SHOWS THE SYSTEM HAS, FOR THE MOST PART,
MAINTAINED OVERALL CONVECTIVE DEPTH AND SPIRAL BANDING. THE INITIAL
POSITION IS BASED ON A CLOUD-FILLED EYE FEATURE ON THE EIR LOOP WITH
FAIR CONFIDENCE. THE INITIAL INTENSITY REMAINS AT 90 KNOTS AND IS
BASED ON AN OVERALL ASSESSMENT OF DVORAK ESTIMATES FROM PGTW AND
KNES. UPPER-LEVEL ANALYSIS INDICATES THE SYSTEM IS IN AN AREA OF
LIGHT VERTICAL WIND SHEAR (VWS) AND IS SURROUNDED BY ANTICYCLONIC
FLOW THAT IS PROVIDING EXCELLENT RADIAL OUTFLOW WITH A STRONG
POLEWARD BIAS. TC 22S IS CURRENTLY TRACKING UNDER THE STEERING
INFLUENCE OF THE NEAR-EQUATORIAL RIDGE TO THE NORTHEAST. THE SYSTEM
WILL TRANSITION TO A BUILDING SUB-TROPICAL RIDGE TO THE EAST AFTER
TAU 36 BUT WILL REMAIN ON A SOUTH-SOUTHEASTWARD TRAJECTORY. TC
JOALANE WILL INTENSIFY SLIGHTLY OVER THE NEXT 24 HOURS AS FAVORABLE
UPPER-LEVEL CONDITIONS PERSIST. HOWEVER, BEYOND TAU 24, TC 22S IS
FORECAST TO GRADUALLY WEAKEN AS IT ENCOUNTERS MODERATE (20 TO 25
KNOT) VWS AND COOLING SEA SURFACE TEMPERATURES. BY TAU 72, THE SYSTEM
WILL BEGIN TO INTERACT WITH THE MID-LATITUDE WESTERLIES AND IS
EXPECTED TO COMPLETE EXTRA-TROPICAL TRANSITION BY THE END OF THE
FORECAST. AVAILABLE MODEL GUIDANCE REMAINS IN GOOD AGREEMENT LENDING
HIGH CONFIDENCE IN THE JTWC TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 090000Z IS 28 FEET. NEXT WARNINGS AT 091500Z AND 100300Z.//

REMARKS:
091500Z POSITION NEAR 17.3S 65.9E.
TROPICAL CYCLONE 22S (JOALANE), LOCATED APPROXIMATELY 513 NM
EAST-NORTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTHWARD AT
06 KNOTS OVER THE PAST SIX HOURS. MULTISPECTRAL SATELLITE IMAGERY
(MSI) SHOWS A VERY SMALL (7NM) EYE FEATURE, AND DEEP CONVECTIVE
SPIRAL BANDING CONTINUING TO WRAP INTO THE LOW LEVEL CIRCULATION
CENTER. THE INITIAL POSITION IS BASED ON THE MSI LOOP WITH GOOD
CONFIDENCE AND THE INTENSITY HAS BEEN LOWERED TO 80 KNOTS BASED ON
CURRENT INTENSITY DVORAK ESTIMATES FROM KNES, PGTW AND FIMP. UPPER
LEVEL ANALYSIS DEPICTS VERY GOOD POLEWARD OUTFLOW AND LOW (5 TO 10
KNOT) VERTICAL WIND SHEAR (VWS). THE SYSTEM IS CURRENTLY TRACKING
ALONG THE SOUTHEASTERN PERIPHERY OF A BUILDING NEAR EQUATORIAL RIDGE
(NER). THE SYSTEM WILL CONTINUE TO TRACK TO THE SOUTHEAST DESPITE A
TRANSFER OF THE STEERING MECHANISM FROM THE NER TO A SUBTROPICAL
RIDGE BUILDING IN TO THE EAST BY TAU 36. WHILE THERE MAY BE SOME
INTENSIFICATION DUE TO GOOD UPPER-LEVEL ENVIRONMENT BEFORE THIS
TIME, TC 22S WILL BEGIN TO DISSIPATE BEYOND TAU 24 DUE TO AN
INCREASE IN VWS AS WELL AS THE OCEAN HEAT CONTENT AND SEA SURFACE
TEMPERATURES BECOMING UNFAVORABLE AS THE SYSTEM TRACKS POLEWARD OF
22 DEGREES SOUTH. BY TAU 72, THE SYSTEM WILL START TO BE INFLUENCED
BY THE MID-LATITUDE WESTERLIES, INITIATING EXTRA-TROPICAL TRANSITION
(ETT) AND COMPLETING ETT BY TAU 120. DYNAMIC MODEL GUIDANCE IS IN
OVERALL GOOD AGREEMENT GIVING HIGH CONFIDENCE IN THE JTWC FORECAST
TRACK WHICH IS LAID CLOSE TO THE MULTI-MODEL CONSENSUS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 091200Z IS 28 FEET. NEXT WARNINGS AT
100300Z AND 101500Z.//

REMARKS:
100300Z POSITION NEAR 18.4S 66.1E.
TROPICAL CYCLONE (TC) 22S (JOALANE), LOCATED APPROXIMATELY 502 NM
EAST-NORTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTHWARD AT 05
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY SHOWS THE SYSTEM HAS MAINTAINED CONVECTIVE DEPTH AND OVERALL
SPIRAL SIGNATURE AS IT TRACKED FURTHER POLEWARD. THE INITIAL
INTENSITY AND POSITION ARE BASED ON CONCENTRIC AND CONGRUENT DVORAK
FIXES FROM PGTW AND KNES. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM
IS NOW 05 DEGREES SOUTH OF THE RIDGE AXIS IN AN AREA OF LIGHT TO
MODERATE (10-15 KNOT) VERTICAL WIND SHEAR (VWS). HOWEVER, THERE
REMAINS A GOOD POLEWARD OUTFLOW THAT IS SUSTAINING THE CONVECTION.
THE SYSTEM IS CURRENTLY TRACKING ALONG THE SOUTHEASTERN PERIPHERY OF
AN EXTENSION OF THE NEAR EQUATORIAL RIDGE (NER) TO THE NORTH. THE
SYSTEM WILL CONTINUE TO TRACK TO THE SOUTHEAST DESPITE A SWITCH IN
THE STEERING MECHANISM FROM THE NER TO A SUBTROPICAL RIDGE BUILDING
IN FROM THE EAST BY TAU 24. TC 22S WILL BEGIN TO WEAKEN AFTER TAU 12
DUE TO INCREASING VWS AND COOLING SEA SURFACE TEMPERATURES. BY TAU
48, THE TC WILL BEGIN EXTRA-TROPICAL TRANSITION (ETT), COMPLETING ETT
BY TAU 96. THE AVAILABLE NUMERIC GUIDANCE REMAINS IN GOOD AGREEMENT,
LENDING HIGH CONFIDENCE TO THE JTWC TRACK FORECAST. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 100000Z IS 28 FEET. NEXT WARNINGS AT
101500Z AND 110300Z.//

REMARKS:
100900Z POSITION NEAR 18.5S 66.4E.
TROPICAL CYCLONE 22S (JOALANE), LOCATED APPROXIMATELY 517 NM EAST
OF PORT LOUIS, MAURITIUS, HAS TRACKED EAST-SOUTHEASTWARD AT 03
KNOTS OVER THE PAST SIX HOURS. MULTISPECTRAL SATELLITE IMAGERY (MSI)
SHOWS A CLOUD FILLED EYE FEATURE WITH TIGHT BANDING CONTINUING TO
WRAP INTO THE LOW LEVEL CIRCULATION CENTER. A 100316Z SSMIS 91H
IMAGE SHOWS THIS TIGHT WRAPPING AS WELL AS A MORE RECENT (100451Z)
AMSU-B MICROWAVE IMAGE. THE LOCATION IS BASED ON THE ABOVE IMAGERY
WITH GOOD CONFIDENCE. THE INTENSITY OF 75 KNOTS IS MAINTAINED DUE TO
AGREEING DVORAK INTENSITY ESTIMATES FROM PGTW AND KNES. UPPER LEVEL
ANALYSIS SHOWS THAT THE SYSTEM REMAINS IN AN AREA OF LOW VERTICAL
WIND SHEAR (VWS) AND GOOD POLEWARD OUTFLOW. TC JOALANE IS CURRENTLY
TRACKING UNDER THE INFLUENCE OF A NEAR EQUATORIAL RIDGE. THE SYSTEM
WILL TRACK TO THE SOUTHEAST THROUGH TAU 24 WHEN A BUILDING
SUBTROPICAL RIDGE (STR) TO THE EAST WILL TAKE OVER THE STEERING
ENVIRONMENT. EXPECT THE SYSTEM TO TRACK MORE SOUTHWARD THROUGH THE
REMAINDER OF THE FORECAST PERIOD, WITH A SLIGHT WESTWARD TURN AT TAU
48-72 AS THE STR REORIENTS. ADDITIONALLY, BY TAU 24, INCREASING VWS
AND LOWER OCEAN HEAT CONTENT WILL CAUSE TC JOALANE TO DISSIPATE
THROUGH THE END OF THE FORECAST PERIOD. BY TAU 48, THE SYSTEM WILL
INTERACT WITH MID-LATITUDE WESTERLIES AND BEGIN EXTRA-TROPICAL
TRANSITION (ETT), COMPLETING ETT BY TAU 96. DYNAMIC MODEL GUIDANCE
IS IN GOOD AGREEMENT LEADING TO HIGH CONFIDENCE IN THE JTWC FORECAST
TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 100600Z IS 30 FEET. NEXT

REMARKS:
102100Z POSITION NEAR 19.7S 67.0E.
TROPICAL CYCLONE (TC) 22S (JOALANE), LOCATED APPROXIMATELY 544 NM
EAST OF PORT LOUIS, MAURITIUS HAS TRACKED SOUTHEASTWARD AT 05 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS TIGHTLY CURVED CONVECTIVE BANDING WRAPPING INTO THE
LOW LEVEL CIRCULATION CENTER (LLCC). THE WATER VAPOR LOOP SHOWS THAT
DRY AIR WEST OF THE SYSTEM IS WRAPPING AROUND THE NORTHERN
PERIPHERY, INDICATING INTERACTION WITH THE MID-LATITUDE TROUGH
PASSING TO THE SOUTH. A 101720Z AMSU-B COMPOSITE IMAGE SHOWS A
PARTIALLY EXPOSED BUT TIGHTLY CURVED LLCC WITH A WEAK REFLECTION OF
THE PERSISTENT MICROWAVE EYE FEATURE WHICH SUPPORTS THE CURRENT
POSITION WITH GOOD CONFIDENCE. THE INITIAL INTENSITY IS HELD AT 75
KNOTS BASED ON AGENCY CURRENT INTENSITY ESTIMATES OF T4.5 (77 KNOTS)
FROM PGTW, FMEE, AND FIMP AND REFLECTS NO OVERALL CHANGE IN THE
CONVECTIVE SIGNATURE OVER THE PAST SIX HOURS. UPPER LEVEL ANALYSIS
INDICATES A MARGINAL ENVIRONMENT WITH LOW TO MODERATE (15-20 KNOT)
NORTHWESTERLY VERTICAL WIND SHEAR (VWS) THAT IS BEING OFFSET BY A
POINT SOURCE JUST NORTH OF THE LLCC AND EXCELLENT POLEWARD OUTFLOW
THAT IS SUSTAINING CONVECTION. TC 22S IS TRACKING UNDER THE
INFLUENCE OF THE BUILDING SUB-TROPICAL RIDGE (STR) TO THE EAST. THIS
STR IS EXPECTED TO REORIENT SLIGHTLY AS THE TROUGH TO THE SOUTH
MOVES DOWNSTREAM CREATING A SOUTHWARD AND THEN SOUTH-SOUTHWESTWARD
TRACK PRIOR TO THE SYSTEM ROUNDING THE STR AXIS. TC JOALANE WILL
BEGIN TO WEAKEN OVER THE NEXT 12 TO 24 HOURS AS VWS INCREASES
SIGNIFICANTLY (ABOVE 35 KNOTS) AND SEA SURFACE TEMPERATURES DROP
BELOW 26 CELSIUS NEAR THE 22 DEGREE LATITUDE. AS THE SYSTEM NEARS
DISSIPATION, IT WILL ALSO INTERACT WITH THE MID-LATITUDE WESTERLIES,
BEGINNING EXTRA-TROPICAL TRANSITION (ETT). TC 22S WILL COMPLETE ETT
BY THE END OF THE FORECAST PERIOD AS A WEAK COLD CORE LOW. DYNAMIC
MODEL GUIDANCE REMAINS IN GOOD OVERALL AGREEMENT, LENDING TO HIGH
CONFIDENCE IN THE JTWC FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
101800Z IS 30 FEET. NEXT WARNINGS AT 110900Z AND 112100Z.//
