SUBJ/TROPICAL CYCLONE FORMATION ALERT/041621ZMAR2008//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
120 NM EITHER SIDE OF A LINE FROM 11.4S 55.7E TO 12.2S 49.9E
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 27 TO 32 KNOTS. METSAT IM-
AGERY AT 041200Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 11.4S 55.4E. THE SYSTEM IS MOVING WESTWARD AT 13 KNOTS.
2. REMARKS: AN AREA OF CONVECTION HAS PERSISTED NEAR 11.4S 55.4E,
APPROXIMATELY 670 NM NORTHEAST OF ANTANANARIVO, MADAGASCAR. RECENT
ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS DEEP CONVECTION
PERSISTING ON THE WESTERN PERIPHERY OF A PARTIALLY-EXPOSED LOW-LEVEL
CIRCULATION CENTER (LLCC) ALSO EVIDENT IN A 041013Z AMSR-E MICROWAVE
IMAGE. THE LLCC LIES NORTH OF AN UPPER-LEVEL RIDGE AXIS IN AN AREA
OF MODERATE EASTERLY VERTICAL WIND SHEAR AND FAVORABLE DIFFLUENCE
ALOFT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 27 TO 32
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB.
BASED ON THE STRONG LOW-LEVEL SIGNATURE AND INCREASING DEEP
CONVECTION, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED
BY 051630Z.//

REMARKS:
050300Z POSITION NEAR 12.0S 52.9E.
TROPICAL CYCLONE (TC) 22S (NONAME) LOCATED APPROXIMATELY 570 NM
NORTHEAST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED WESTWARD AT
14 KNOTS OVER THE PAST 06 HOURS. TC 22S HAS A WELL-DEFINED LOW
LEVEL CIRCULATION CENTER WITH THE MAJORITY OF THE DEEP CONVECTION
DISPLACED TO THE WEST. THIS DISPLACEMENT IS DUE TO MODERATE
EASTERLY VERTICAL WIND SHEAR. THE LIMITING FACTOR OF THE SHEAR
IS BEING OFFSET BY FAVORABLE OCEAN HEAT CONTENT AND GOOD UPPER
LEVEL OUTFLOW. TC 22S WILL CONTINUE TO TRACK GENERALLY WESTWARD
ALONG THE PERIPHERY OF A LOW- TO MID-LEVEL RIDGE TO THE SOUTH
OF THE STORM THROUGH THE ENTIRE FORECAST PERIOD. THIS TRACK WILL
CAUSE LAND FALL AROUND TAU 24 TO THE NORTHERN TIP OF MADAGASCAR.
THE STORM WILL CONTINUE TO INCREASE IN INTENSITY UNTIL LANDFALL
AFTER WHICH LAND INTERACTION WILL LIMIT INTENSIFICATION. THE
STORM WILL REMERGE INTO THE MOZAMBIQUE CHANNEL PRIOR TO TAU 36
AND INTENSIFY DUE TO A FAVORABLE UPPER LEVEL ENVIRONMENT AND
SEA SURFACE TEMPERATURES. THE FORECAST TRACK AND INTENSITY ARE
CLOSE TO THE CONSENSUS OF THE NUMERICAL AND STATISTICAL MODELS,
WHICH ARE IN GOOD AGREEMENT. THIS WARNING SUPERSEDES AND CANCELS
REF A, NAVPACMETOCCEN 041621ZMAR2008 TROPICAL CYCLONE FORMATION

REMARKS:
051500Z POSITION NEAR 12.0S 50.2E.
TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 480 NM
NORTH-NORTHEAST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED WESTWARD
AT 13 KNOTS OVER THE PAST 06 HOURS. TC 22S IS TRACKING ALONG THE
NORTHERN PERIPHERY OF A SUBTROPICAL STEERING RIDGE LOCATED TO THE
SOUTH OF THE STORM. THE SYSTEM WILL CONTINUE TRACKING ALONG THE
STEERING RIDGE PERIPHERY TOWARD A MID-LATITUDE TROUGH DEVELOPING
OVER THE SOUTHERN MOZAMBIQUE CHANNEL DURING THE FORECAST PERIOD.
TC 22S HAS INTENSIFIED OVER THE PAST 12 HOURS IN RESPONSE TO
DECREASING EASTERLY VERTICAL WIND SHEAR AND FAVORABLE OCEAN HEAT
CONTENT. THIS INTENSIFICATION TREND IS EXPECTED TO CONTINUE
DURING THE NEXT 24 HOURS WITH SOME LIMITATION IMPOSED BY LAND
INTERACTION AND PERSISTENT, THOUGH MODERATE, VERTICAL WIND SHEAR.
AFTER TAU 24, THE STORM MAY EXPERIENCE A PERIOD OF RAPID INTENSI-
FICATION AS IT MOVES UNDER AN UPPER-LEVEL ANTICYCLONE AND OVER
VERY WARM WATER IN THE NORTHERN MOZAMBIQUE CHANNEL. THE TRACK
FORECAST IS CLOSE TO THE TIGHTLY-PACKED NUMERICAL MODEL GUIDANCE
AND THE INTENSITY FORECAST IS SLIGHTLY BELOW THE STATISTICAL
GUIDANCE, WHICH ESTIMATES A STRONGER INTENSIFICATION TREND DURING
THE FIRST 24 HOURS OF THE FORECAST PERIOD. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 051200Z IS 16 FEET. NEXT WARNINGS AT 060300Z AND
061500Z. REFER TO TROPICAL CYCLONE 21S (OPHELIA) WARNINGS

REMARKS:
060300Z POSITION NEAR 12.1S 48.7E.
TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 430 NM
NORTH-NORTHEAST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED WEST-SOUTH-
WESTWARD AT 07 KNOTS OVER THE PAST 06 HOURS. TC 22S IS TRACKING ALONG
THE NORTHERN PERIPHERY OF A SUBTROPICAL STEERING RIDGE LOCATED TO THE
SOUTH OF THE STORM TOWARD A MID-LATITUDE TROUGH DEVELOPING OVER THE
SOUTHERN MOZAMBIQUE CHANNEL. THE SYSTEM INTENSITY HAS DIMINISHED SLI-
GHTLY OVER THE PAST 12 HOURS IN RESPONSE TO INCREASED INTERACTION WI-
TH LAND. AS TC 22S MOVES WEST OVER THE MORE FAVORABLE CONDITIONS FOU-
ND IN THE MOZAMBIQUE CHANNEL INTENSIFICATION IS EXPECTED TO RESUME AS
THE STORM ENCOUNTERS IMPROVED OCEAN HEAT CONTENT AND MODERATE, VERTI-
CAL WIND SHEAR. THIS INTENSIFICATION WILL BE AIDED BY THE INFLUENCE
OF AN UPPER-LEVEL ANTICYCLONE WHICH WILL MOVE IN OVER THE STORM ASS-
ISTING WITH OUTFLOW ALOFT. THE TRACK FORECAST IS CLOSE TO THE TIGHT-
LY-PACKED NUMERICAL MODEL GUIDANCE AND THE INTENSITY FORECAST IS SL-
IGHTLY ABOVE THE STATISTICAL GUIDANCE. MAXIMUM SIGNIFICANT WAVE HEI-
GHT AT 060000Z IS 17 FEET. NEXT WARNINGS AT 061500Z AND 070300Z.

REMARKS:
061500Z POSITION NEAR 14.0S 46.3E.
TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 315 NM
NORTH OF ANTANANARIVO, MADAGASCAR, HAS TRACKED WEST-SOUTHWESTWARD
AT 12 KNOTS OVER THE PAST 06 HOURS. TC 22S IS TRACKING ALONG THE
NORTHWESTERN PERIPHERY OF A SUBTROPICAL STEERING RIDGE LOCATED TO
THE SOUTH OF THE STORM. THE STORM IS EXPECTED TO MAINTAIN THIS TRACK
THROUGH THE FORECAST PERIOD WITH A SLIGHT DECREASE IN FORWARD MOTION
NEAR TAU 48. THE SYSTEM HAS INTENSIFIED RAPIDLY AFTER CROSSING OVER
NORTHERN MADAGASCAR NEARLY 12 HOURS AGO. THE CURRENT INTENSITY IS
SUPPORTED BY SATELLITE INTENSITY ESTIMATES OF 77 KNOTS FROM ALL
AVAILABLE AGENCIES. TC 22S WILL CONTINUE TO INTENSIFY DUE TO THE
EXPECTED FAVORABLE OCEAN HEAT CONTENT ALONG ITS TRACK. GOOD RADIAL
OUTFLOW ALOFT WILL ALSO AID IN INTENSIFICATION THROUGH TAU 36. AFTER
THIS TIME, INTENSIFICATION WILL BE LIMITED DUE TO THE OFFSETTING
INFLUENCES OF HIGH OCEAN HEAT CONTENT AND INTERACTION WITH LAND.
THE TRACK FORECAST IS CLOSE TO THE TIGHTLY-PACKED NUMERICAL MODEL
GUIDANCE AND THE INTENSITY FORECAST IS NEAR THE STATISTICAL GUIDANCE.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 061200Z IS 22 FEET. NEXT WARNINGS

REMARKS:
070300Z POSITION NEAR 15.1S 44.8E.
TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 275 NM
NORTH-NORTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED SOUTHWEST-
WARD AT 10 KNOTS OVER THE PAST 06 HOURS. TC 22S IS TRACKING ALONG THE
NORTHWESTERN PERIPHERY OF A SUBTROPICAL STEERING RIDGE LOCATED TO
THE SOUTHEAST OF THE STORM. THE STORM IS EXPECTED TO MAINTAIN THIS TRACK
THROUGH THE FORECAST PERIOD WITH A SLIGHT DECREASE IN FORWARD MOTION
NEAR TAU 48. THE CURRENT INTENSITY IS SUPPORTED BY SATELLITE INTENSITY
ESTIMATES RANGING BETWEEN 65 AND 77 KNOTS. TC 22S WILL INTENSIFY
SLIGHTLY THROUGH TAU 12 AND THEN BEGIN A SLOW WEAKENING TREND FOR THE
REMAINDER OF THE FORECAST PERIOD DUE TO INTERACTION WITH LAND AND
THE INLFUENCES OF AN AREA OF LOWER OCEAN HEAT CONTENT NEAR TAU 24. THE
TRACK FORECAST IS CLOSE TO THE TIGHTLY-PACKED NUMERICAL MODEL GUIDANCE
AND THE INTENSITY FORECAST IS NEAR THE STATISTICAL GUIDANCE. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 070000Z IS 24 FEET. NEXT WARNINGS AT
071500Z AND 080300Z.

TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 375
NM NORTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED WEST-
SOUTHWESTWARD AT 08 KNOTS OVER THE PAST 06 HOURS. TC 22S IS
TRACKING ALONG THE NORTHWESTERN PERIPHERY OF A SUBTROPICAL
STEERING RIDGE LOCATED TO THE SOUTHEAST OF THE STORM. THE
STORM IS EXPECTED TO CONTINUE A SOUTHWESTWARD TRACK OVER THE
REMAINDER OF THE FORECAST PERIOD. THE SYSTEM HAS ONCE AGAIN
INTENSIFIED AND IS DISPLAYING A 07 NM DIAMETER EYE. THE
CURRENT INTENSITY IS SUPPORTED BY SATELLITE INTENSITY ESTIMATES
OF 90 TO 102 KNOTS FROM THE AVAILABLE FIX AGENCIES. TC 22S
WILL MAINTAIN THIS STRENGTH THROUGH TAU 12 AND THEN BEGIN
TO WEAKEN DUE TO LAND INTERACTION AND AN INCREASE IN VERTICAL
WIND SHEAR AS IT TRACKS ALONG THE COAST OF MOZAMBIQUE. THE
STORM WILL MOVE AWAY FROM THE COASTLINE BY TAU 36 AND MAINTAIN
STRENGTH FOR THE REST OF THE PERIOD. THE TRACK FORECAST REMAINS
CLOSE TO THE NUMERICAL MODEL GUIDANCE THAT IS IN GOOD AGREEMENT.
THE INTENSITY FORECAST IS BELOW THE STATISTICAL GUIDANCE DUE
TO THE ANTICIPATED LAND INTERACTION. THE FORECAST INTENSITIES
OVER THE FIRST 24 HOURS ARE HIGHER THAN THE PREVIOUS FORECAST
DUE TO STRONGER THAN ANTICIPATED INTENSIFICATION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 071800Z IS 28 FEET. NEXT WARNINGS

TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 420 NM
WEST-NORTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED WEST-
SOUTHWESTWARD AT 04 KNOTS OVER THE PAST 06 HOURS. TC 22S
CONTINUES TO TRACK ALONG THE NORTHWESTERN PERIPHERY OF A
SUBTROPICAL STEERING RIDGE TO THE SOUTHEAST. RECENT SATELLITE
INTENSITY ESTIMATES FROM VARIOUS REPORTING AGENCIES SUGGEST
THAT THE SYSTEM HAS INTENSIFIED SLIGHTLY OVER THE PAST 12 HOURS
UNDER THE INFLUENCES OF EXCELLENT UPPER LEVEL OUTFLOW AND HIGH
OCEAN HEAT CONTENT. AT 08/06Z, THE STORM EXHIBITED A SMALL,
7 NM DIAMETER EYE IN SATELLITE IMAGERY. TC 22S IS EXPECTED TO
CONTINUE TRACKING GENERALLY SOUTHWESTWARD TO SOUTHWARD AROUND
THE PERIPHERY OF THE PRESENT STEERING RIDGE TOWARD THE BASE OF
A DEVELOPING MID-LATITUDE TROUGH OVER THE SOUTHERN MOZAMBIQUE
CHANNEL. THIS TRACK WILL TAKE THE SYSTEM CENTER ACROSS LAND
IN NORTHEASTERN MOZAMBIQUE OVER THE NEXT 24 HOURS, WHICH SHOULD
RESULT IN SIGNIFICANT WEAKENING. AFTER TAU 24, THE SYSTEM WILL
REEMERGE OVER WATER, WHERE INCREASING VERTICAL WIND SHEAR
INDUCED BY THE AFOREMENTIONED TROUGH WILL COMPETE WITH FAVORABLE
OCEAN HEAT CONTENT AND GOOD UPPER LEVEL OUTFLOW TO HOLD STORM
INTENSITY NEARLY STEADY. THE NUMERICAL MODEL TRACK GUIDANCE HAS
BEGUN TO DIVERGE, WITH NOGAPS AND GFDN PREDICTING WEST-SOUTH-
WESTWARD TRACK AND EVENTUAL DISSIPATION OVER LAND AND THE OTHER
MODELS PREDICTING AN EVENTUAL POLEWARD RECURVATURE. THIS FORECAST
FAVORS THE RECURVATURE SCENARIO DUE TO THE PREDICTED INTERACTION
WITH THE MID-LATITUDE TROUGH TO THE SOUTHWEST. THE INTENSITY
FORECAST IS A BIT LOWER THAN THE STATISTICAL MODEL GUIDANCE
BASED ON THE ANTICIPATION OF HIGHLY UNFAVORABLE LAND INTERACTION
OVER THE NEXT 24 HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
080600Z IS 30 FEET. NEXT WARNINGS AT 082100Z AND 090900Z. REFER

TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 290 NM
WEST-NORTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED WEST-
SOUTHWESTWARD AT 07 KNOTS OVER THE PAST 06 HOURS. TC 22S
CONTINUES TO TRACK ALONG THE NORTHWESTERN PERIPHERY OF A
SUBTROPICAL STEERING RIDGE TO THE SOUTHEAST. RECENT SATELLITE
INTENSITY ESTIMATES FROM VARIOUS REPORTING AGENCIES SUGGEST
THAT THE SYSTEM HAS WEAKENED OVER THE PAST 12 HOURS. TC 22S
IS EXPECTED TO CONTINUE TRACKING GENERALLY SOUTHWESTWARD TO
SOUTHWARD AROUND THE PERIPHERY OF THE STEERING RIDGE TOWARD A
RECENTLY DEVELOPED UPPER LEVEL LOW TO THE SOUTH-SOUTHWEST OF
THE STORM. THIS TRACK WILL TAKE THE SYSTEM CENTER BACK OVER
THE MOZAMBIQUE IN THE NEXT 06 HOURS. DURING THIS TIME SLIGHT
WEAKENING IS EXPECTED DUE TO THE LAND INTERACTION. ONCE BACK
OVER THE FAVORABLE WATERS OF THE CHANNEL, INTENSIFICATION IS
EXPECTED WITH THE AID OF THE GOOD POLEWARD OUTFLOW SUPPLIED BY
THE AFOREMENTIONED UPPER LEVEL LOW. AFTER TAU 24, THE PROXIMITY
OF THE UPPER LEVEL LOW WILL CAUSE AN INCREASE IN VERTICAL WIND
SHEAR. THE INCREASING WIND SHEAR WILL OFFSET THE FAVORABLE
OUTFLOW AND WARM WATERS AS THE STORM BEGINS TO WEAKEN. THE
FORECAST INTENSITIES ARE HIGHER THAN THE PREVIOUS FORECAST DUE
TO THE LESS THAN ANTICIPATED WEAKENING OF THE STORM WHILE OVER
LAND. OVERALL, THE FORECAST IS IN GOOD AGREEMENT WITH THE

REMARKS:
090900Z POSITION NEAR 17.4S 39.3E.
TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 450 NM WEST-
NORTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED SOUTH-SOUTHWEST-
WARD AT 05 KNOTS OVER THE PAST 06 HOURS. TC 22S CONTINUES TO TRACK
ALONG THE NORTHWESTERN PERIPHERY OF A SUBTROPICAL STEERING RIDGE TO
THE SOUTHEAST. THE STORM CENTER HAS REEMERGED OVER THE MOZAMBIQUE
CHANNEL AFTER MOVING OVER NORTHEASTERN MOZAMBIQUE FOR ABOUT 18 HOURS.
PASSAGE OVER WARM WATER AND GOOD POLEWARD OUTFLOW AHEAD OF A DEVELOP-
ING MID-LATITUDE TROUGH TO THE SOUTHWEST HAVE ALLOWED THE STORM TO
NEARLY MAINTAIN INTENSITY DESPITE THE CONTINUED INTERACTION OF LAND
WITH THE NORTHWESTERN PERIPHERY OF THE STORM CIRCULATION. THE SYSTEM
IS EXPECTED TO CONTINUE TRACKING ALONG THE CURRENT STEERING RIDGE
TOWARD A DEVELOPING UPPER LEVEL LOW TO THE SOUTHWEST. THIS LOW
PRESSURE AREA IS EXPECTED TO CUTOFF FROM THE MID-LATITUDE FLOW
PATTERN AND LOITER IN THE SOUTHERN MOZAMBIQUE CHANNEL DURING THE
NEXT SEVERAL DAYS. TC 22S WILL GRADUALLY MOVE CLOSER TO THIS LOW
DURING THE FORECAST PERIOD, WHICH SHOULD INDUCE SOME CYCLONIC MOVE-
MENT IN THE STORM TRACK AFTER TAU 24 AS THE TWO CIRCULATIONS
INTERACT. GOOD POLEWARD OUTFLOW AND FAVORABLE ALONG-TRACK OCEAN HEAT
CONTENT WILL ALLOW TC 22S TO INTENSIFY A BIT OVER THE NEXT 24 HOURS,
BUT ENHANCED UPPER LEVEL WESTERLIES ALONG THE NORTHERN PERIPHERY OF
THE DEVELOPING LOW TO THE SOUTHWEST WILL RESULT IN SOME WEAKENING
AFTER TAU 24. INTERACTION BETWEEN THE TROPICAL CYCLONE AND NON-
TROPICAL CUTOFF LOW TO THE SOUTHWEST MAY LEAD TO EVENTUAL MERGER OF
THE TWO CIRCULATIONS, WHICH SHOULD FURTHER WEAKEN THE TROPICAL
CYCLONE. HOWEVER, THIS MERGER WILL PROBABLY NOT BE COMPLETE UNTIL
AFTER THE CURRENT FORECAST PERIOD. THE TRACK AND INTENITY FORECASTS
REMAIN CLOSE TO THEIR RESPECTIVE NUMERICAL AND STATISTICAL MODEL
CONSENSUSES. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 090600Z IS 32 FEET.

WARD AT 07 KNOTS OVER THE PAST 06 HOURS. TC 22S CONTINUES TO TRACK
POLEWARD ALONG THE WESTERN PERIPHERY OF A SUBTROPICAL RIDGE TO THE
EAST. THE STORM HAS MAINTAINED INTENSITY OVER THE PAST 12 HOURS
UNDER THE COMPETING INFLUENCES OF FAVORABLE OCEAN HEAT CONTENT
AND GOOD POLEWARD OUTFLOW AHEAD OF AN UPPER-LEVEL TROUGH TO THE
SOUTHWEST AND UNFAVORABLE, INCREASING NORTHWESTERLY VERTICAL WIND
SHEAR. TC 22S IS EXPECTED TO CONTINUE TRACKING POLEWARD ALONG THE
CURRENT STEERING RIDGE PERIPHERY TOWARD THE BASE OF THE AFOREMEN-
TIONED UPPER-LEVEL TROUGH TO THE SOUTHWEST. THIS TROUGH AND AN
ASSOCIATED CUTOFF, UPPER-LEVEL LOW OVER THE SOUTHERN MOZAMBIQUE
CHANNEL ARE EXPECTED TO INDUCE SOME CYCLONIC CURVATURE IN THE
STORM TRACK THROUGH TAU 48 DUE TO MID-LEVEL INTERACTION BETWEEN
THE STORM AND TROUGH CIRCULATIONS. AS THE STORM NEARS THE UPPER-
LEVEL TROUGH, INCREASING VERTICAL WIND SHEAR AND THE INTRODUCTION
OF DRIER, SUBSIDENT AIR WILL WEAKEN TC 22S. AS THIS INTERACTION
PROGRESSES, PARTICULARLY BETWEEN TAU 24 AND TAU 48, THE STORM IS

110900Z POSITION NEAR 23.7S 41.2E.
TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 420 NM
SOUTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED SOUTH-SOUTHEAST-
WARD AT 07 KNOTS OVER THE PAST 06 HOURS. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS A BANDING EYE WITH A SLIGHT DECREASE IN
DEEP CONVECTION OVER THE NORTH QUADRANT OF THE SYSTEM. AN 110406Z
SSMI 37 GHZ IMAGE SHOWS A WELL-DEFINED MICROWAVE EYE FEATURE,
THEREFORE, THERE IS GOOD CONFIDENCE IN THE CURRENT POSITION AND
DECREASE IN TRACK SPEED. THERE IS NO SIGNIFICANT CHANGE TO THE
FORECAST PHILOSOPHY SINCE THE PREVIOUS FORECAST ALTHOUGH THE
SYSTEM HAS TRACKED MORE SOUTHEASTWARD THAN EXPECTED POSSIBLY DUE
TO THE INFLUENCE OF THE DEEP UPPER-LEVEL LOW POSITIONED SOUTH-
SOUTHWEST OF THE SYSTEM. THIS LOW IS FORECAST TO WEAKEN AND TC 22S
IS EXPECTED TO TRACK SOUTHWARD THROUGH TAU 12 ALONG THE WESTERN
PERIPHERY OF THE MID-LEVEL SUBTROPICAL RIDGE TO THE EAST. AFTER
TAU 12, TC 22S WILL TURN INCREASINGLY WESTWARD AND SLOW AS A WEAK
STEERING RIDGE BUILDS TO ITS SOUTH. TC 22S IS FORECAST TO WEAKEN
UNDER INCREASING VERTICAL WIND SHEAR AND MARGINAL OCEAN HEAT
CONTENT. IT IS LIKELY THAT THE STORM WILL REMAIN IN A WEAK STEERING
ENVIRONMENT WITH SLOW OR QUASI-STATIONARY MOTION AFTER TAU 24.
THE CURRENT FORECAST IS BASED ON THE MODEL CONSENSUS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 110600Z IS 26 FEET. NEXT WARNINGS AT
112100Z AND 120900Z. REFER TO TROPICAL CYCLONE 23S (KAMBA)

120900Z POSITION NEAR 25.2S 40.2E.
TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 530 NM SOUTH-
WEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED WESTWARD AT 05 KNOTS
OVER THE PAST 06 HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS RENEWED DEEP CONVECTIVE BANDING DEVELOPING OVER THE SOUTH
SEMI-CIRCLE. A 120352Z SSMI IMAGE SHOWS A DEVELOPING BANDING EYE
WITH CONVECTION WRAPPING FROM THE EAST INTO THE NORTHWEST QUADRANT.
THE CURRENT POSITION AND MOTION ARE BASED ON THE WELL-DEFINED LOW-
LEVEL CIRCULATION CENTER (LLCC). THE CURRENT INTENSITY IS BASED ON
THE HIGH END OF DVORAK ESTIMATES RANGING FROM 35 TO 55 KNOTS DUE IN
LARGE PART TO IMPROVED ORGANIZATION AND A TIGHTLY-WRAPPED LLCC
ON THE 120347Z QUIKSCAT IMAGE AND AUTOMATED INTENSITY ESTIMATES
RANGING FROM 45 TO 55 KNOTS. THE SYSTEM IS CURRENTLY TRACKING UNDER
THE STEERING INFLUENCE OF A WEAK LOW- TO MID-LEVEL SUBTROPICAL RIDGE
WHICH HAS BUILT IN SOUTH OF THE SYSTEM. TC 22S IS FORECAST TO RE-
MAIN SITUATED WITHIN A WEAK STEERING THROUGH THE FORECAST PERIOD
AND WILL LIKELY MAINTAIN A SLOW, QUASI-STATIONARY MOTION UNTIL AN
APPROACHING MIDLATITUDE TROUGH INDUCES A SOUTH TO SOUTHEASTWARD
STEERING INFLUENCE AFTER TAU 72. THE CURRENT FORECAST IS BASED ON
THE CONSENSUS BUT IS SLOWER AFTER TAU 24. TC 22S IS TRACKING OVER
GENERALLY FAVORABLE SST AND OCEAN HEAT CONTENT WITH IMPROVED
POLEWARD OUTFLOW OVER THE PAST 12 HOURS ENHANCED BY AN UPPER-LOW

122100Z POSITION NEAR 25.7S 40.2E.
TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 550 NM SOUTH-
WEST OF ANTANANARIVO, MADAGASCAR, HAS REMAINED QUASI-STATIONARY OVER
THE PAST 06 HOURS. THE INITIAL POSITION IS BASED ON A 1733Z TRMM
MICROWAVE PASS THAT SHOWS DEEP CONVECTION CONFINED TO THE SOUTHERN
SEMI-CIRCLE OF THE STORM. THIS IMPLIES THAT THE STORM IS EXPERIENCING
MODERATE VERTICAL WIND SHEAR. THE STORM HAS INTENSIFIED SLIGHTLY
OVER THE PAST 12 HOURS, WITH THE INITIAL INTENSITY BASED ON DVORAK
ESTIMATES FROM PGTW AND FMEE ALONG WITH QUIKSCAT. THE STORM IS
CURRENTLY IN A WEAK STEERING ENVIRONMENT. THE MODELS, WITH THE
EXCEPTION OF WBAR, ARE IN GOOD AGREEMENT WITH A SLOW EQUATORWARD
TRACK THROUGH TAU 48, AS AN ANTICYCLONE WEST OF THE SYSTEM
STRENGTHENS TO BECOME THE PRIMARY STEERING INFLUENCE. THE
OFFICIAL FORECAST REFLECTS THE POLEWARD TRACK. SOME POSSIBILITY
EXISTS FOR SLIGHT REINTENSIFICATION IF THE STORM MOVES FAR ENOUGH
NORTH TO ENCOUNTER LOWER VERTICAL WIND SHEAR VALUES AND HIGHER OCEAN
HEAT CONTENT. HOWEVER, THE MOST LIKELY TIMING OF THIS POSSIBLE
INTENSIFICATION IS BEYOND TAU 48. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
121800Z IS 18 FEET. NEXT WARNINGS AT 130900Z AND 132100Z.

THAT TC 22S PEAKED IN INTENSITY NEAR 13/03Z WITH DVORAK INTENSITY
ESTIMATES JUMPING TO 77 KNOTS (PGTW, KNES AND FMEE). OVER THE PAST
THREE HOURS, THE SYSTEM HAS WEAKENED WITH THE EYE BECOMING CLOUD-
FILLED AND CONVECTIVE CLOUD TOPS WARMING SIGNIFICANTLY. BASED ON A
130520Z SSMIS IMAGE, THE LOW-LEVEL CIRCULATION CENTER APPEARS TO BE
DISPLACED SLIGHTLY WEST OF THE BULK OF THE CONVECTION. TC 22S IS
EMBEDDED WITHIN A WEAK STEERING ENVIRONMENT WITH LOW- TO MID-LEVEL
SUBTROPICAL RIDGING WEST, NORTH AND SOUTHEAST OF THE SYSTEM,
THEREFORE, THE AVAILABLE MODEL AIDS ARE IN POOR AGREEMENT. THE
CURRENT FORECAST WAS SHIFTED TO A SLOWER, MORE EASTWARD TRACK
THAN THE PREVIOUS FORECAST BASED ON THE CURRENT LOOP AND THE
CONTINUED WEAK STEERING INFLUENCE. MODEL FIELDS INDICATE THAT THE
MOST LIKELY SCENARIO IS A SLOW NORTHEASTWARD TO EASTWARD TRACK

REMARKS:
140900Z POSITION NEAR 25.4S 40.3E.
TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 425 NM
EAST OF MAPUTO, MOZAMBIQUE, HAS REMAINED QUASI-STATIONARY OVER
THE PAST 12 HOURS. RECENT ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS A PARTIALLY EXPOSED LOW-LEVEL CIRCULATION CENTER
WITH REMAINING DEEP CONVECTION CONFINED TO THE EASTERN PERIPHERY.
THE SYSTEM REMAINS IN A WEAK STEERING ENVIRONMENT BETWEEN A SUB-
TROPICAL RIDGE TO THE WEST AND ANOTHER TO THE SOUTHEAST. A LOW
TO MID-LEVEL EXTENSION OF THE RIDGE TO THE WEST IS EXERTING
A SLIGHTLY STRONGER STEERING INFLUENCE, WHICH SHOULD CONTINUE
TO MOVE THE STORM SLIGHTLY WESTWARD TO NORTHWESTWARD THROUGH
THE FORECAST PERIOD. TC 22S IS STEADILY WEAKENING UNDER THE
INFLUENCE OF MODERATE WESTERLY VERTICAL WIND SHEAR AND ITS
MAXIMUM SUSTAINED WIND SPEED IS NOW EXPECTED TO DROP BELOW THE
WARNING THRESHOLD OF 35 KNOTS BY TAU 24 UNDER THE CONTINUED
INFLUENCE OF THIS DESTRUCTIVE SHEAR. FORECAST INTENSITIES HAVE
BEEN REDUCED IN RESPONSE TO THE RECENT STEADY WEAKENING TREND,
BUT THE TRACK FORECAST REMAINS UNCHANGED AND CLOSE TO THE
NUMERICAL MODEL CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 140600Z IS 16 FEET. NEXT WARNINGS AT 142100Z.//

REMARKS:
142100Z POSITION NEAR 25.3S 40.4E.
TROPICAL CYCLONE (TC) 22S (JOKWE) LOCATED APPROXIMATELY 425 NM
EAST OF MAPUTO, MOZAMBIQUE, HAS REMAINED QUASI-STATIONARY OVER
THE PAST 12 HOURS. RECENT ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS AN EXPOSED LOW-LEVEL CIRCULATION CENTER WITH RE-
MAINING CONVECTION SHEARED TO THE NORTH OF THE STORM. TC 22S
REMAINS IN A WEAK STEERING ENVIRONMENT BETWEEN A SUB-TROPICAL
RIDGE TO THE WEST AND ANOTHER TO THE SOUTHEAST. TC 22S CONTINUES
TO STEADILY WEAKEN UNDER THE INFLUENCE OF MODERATE WESTERLY
VERTICAL WIND SHEAR AND LOW OCEAN HEAT CONTENT, AND IS NOW EX-
PECTED TO DROP BELOW 30 KNOTS BY TAU 12. THIS IS THE FINAL
WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER
(NAVPACMETOCCEN). THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS
OF REGENERATION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 141800Z IS
14 FEET.
