031500Z9 POSITION NEAR 13.7S1 63.5E4.
TROPICAL CYCLONE (TC) 28S HAS DEVELOPED WITHIN A NORTHWEST-SOUTHEAST
ORIENTED TROUGH IN THE SOUTH INDIAN OCEAN AND IS APPROXIMATELY 530
NM NORTHEAST OF MAURITIUS. TC 28S HAS TRACKED SOUTH-SOUTHWEST AT 09
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
031130Z8 VISIBLE AND ENHANCED INFRARED SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 35 KNOTS. MULTI-SPECTRAL ANIMATION DEPICTS SIGNIFICANT CONVECTIVE
BANDS SURROUND AN IMPROVING LOW LEVEL CIRCULATION. A SECOND
CIRCULATION APPROXIMATELY 400 NM TO THE NORTHWEST IS ALSO DEVELOPING
BUT DOES NOT MEET WARNING CRITERIA AT THIS TIME. A LOW TO MID-LEVEL
RIDGE TO THE NORTHEAST AND THE SECOND CYCLONIC CIRCULATION ARE
INDUCING A POLEWARD MOTION. AVAILABLE NWP (UKMET, NOGAPS, AND GFS)
IS HAVING DIFFICULTY RESOLVING TC 28S AT THIS TIME. TC 28S IS
FORECAST TO DEVELOP AT A CLIMATOLOGICAL RATE IN A FAVORABLE
ENVIRONMENT. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 031200Z6 IS 13 FEET.

040300Z7 POSITION NEAR 15.5S1 61.1E8.
TROPICAL CYCLONE (TC) 28S, LOCATED APPROXIMATELY 360 NM NORTHEAST OF
MAURITIUS. TC 28S HAS TRACKED SOUTHWESTWARD AT 15 KNOTS DURING THE
PAST 6 HOURS. THE WARNING POSITION IS BASED ON 032330Z1 ENHANCED
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 45 AND 55 KNOTS. THE SYSTEM
HAS CONTINUED TO ORGANIZE OVER THE LOW LEVEL CIRCULATION CENTER OVER
THE PAST 12 HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
REVEALS A SPIRAL BAND WRAPPING IN FROM THE SOUTH OF THE SYSTEM. A
SECOND CIRCULATION APPROXIMATELY 355 NM TO THE NORTH-NORTHWEST OF TC
28S DOES NOT MEET WARNING CRITERIA AT THIS TIME. A LOW TO MID-LEVEL
RIDGE TO THE NORTHEAST, A MID-LEVEL TROUGH TO THE SOUTH AND THE
INFLUENCE OF THE SECOND CIRCULATION ARE INDUCING A SOUTHWESTWARD
TRACK. AS A LOW TO MID-LEVEL RIDGE TO THE SOUTHWEST OF THE SYSTEM
AND THE TROUGH TO THE SOUTH TRANSLATE EASTWARD, TC 28S WILL ALTER
TO A MORE WESTWARD TRACK. THE AVAILABLE DYNAMIC AIDS CONSISTING OF
UKMET (EGRR), NCEP AVIATION (AVN), NOGAPS AND GFDN ARE IN GOOD
AGREEMENT WITH THE FORECAST TRACK, HOWEVER THERE IS AN EQUATORWARD
BIAS DUE TO DIFFICULTIES RESOLVING THE TWO CIRCULATIONS. OUR
FORECAST TRACK IS A BLEND OF ALL THE AVAILABLE AIDS WITH A POLEWARD
BIAS TO ACCOUNT FOR INTERACTION WITH THE SECOND CIRCULATION. TC 28S
IS FORECAST TO DEVELOP AT A CLIMATOLOGICAL RATE IN A FAVORABLE
ENVIRONMENT. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 040000Z4 IS 18 FEET.

TROPICAL CYCLONE (TC) 28S (MANOU), LOCATED APPROXIMATELY 190 NM
NORTH OF MAURITIUS, HAS TRACKED SOUTHWESTWARD AT 07 KNOTS DURING
THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 052330Z3
ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 35 KNOTS AND
SYNOPTIC DATA. ANIMATED INFRARED SATELLITE IMAGERY SUGGESTS THE
LOW LEVEL CIRCULATION CENTER IS PARTIALLY EXPOSED AND LIES TO THE
NORTHEAST OF THE DEEP CONVECTION. TC 28S IS FORECAST TO CONTINUE
TRACKING SOUTHWESTWARD OVER THE NEXT 12 HOURS AS A TROUGH PASSES
POLEWARD OF THE SYSTEM. AFTERWARDS, TC 28S IS FORECAST TO TRACK
WESTWARD AS A MID-LEVEL RIDGE ARRIVES FROM THE SOUTHWEST. TC 28S
IS FORECAST TO MAINTAIN INTENSITY OVER THE FORECAST PERIOD UNDER
WEAK TO MODERATE VERTICAL WIND SHEAR. THE AVAILABLE DYNAMIC AIDS
CONSISTING OF NOGAPS, NCEP AVIATION, GFDN, AND UKMET EGRR ARE IN
FAIR AGREEMENT. THE AVIATION MODEL HAS MORE INTERACTION WITH THE
PASSING TROUGH AND DISSIPATES THE SYSTEM OFF THE COAST OF
MADAGASCAR WHILE THE OTHER AIDS TRACK THE SYSTEM ONTO MADAGASCAR.
OUR FORECAST IS BASED ON A BLEND OF PERSISTENCE AND THE AVAILABLE
AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 06000Z6 IS 18 FEET.

TROPICAL CYCLONE (TC) 28S (MANOU), LOCATED APPROXIMATELY 215 NM 
NORTHWEST OF MAURITIUS, HAS TRACKED WEST-SOUTHWESTWARD AT 09 KNOTS 
IN THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON 061730Z7 
INFRARED SATELLITE IMAGERY AND AVAILABLE SYNOPTIC DATA. THE WARNING 
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 35 
KNOTS AND 40 KNOT SYNOPTIC REPORTS. JUSTIFCAITON FOR AMENDMENT: TC 
28S HAS REINTENSIFIED TO WARNING CRITERIA AND IS EXPECTED TO REMAIN 
AT WARNING CRITERIA UNTIL IT TRACKS ON TO LAND ON MADAGASCAR'S 
EASTERN COAST. TC 28S HAD PREVIOUSLY WEAKENED WITH ITS CONVECTION 
DECOUPLING FROM THE LOW LEVEL CIRCULATION CENTER (LLCC). HOWEVER, 
RECENT ANIMATED INFRARED SATELLITE IMAGERY SHOWS THAT THE SYSTEM HAS 
REINTENSIFIED WITH DEEP CONVECTION REORGANIZING OVER THE LLCC. 
ANALYSIS OF 200 MB SHOWS THAT 28S EXISTS IN A MARGINALLY FAVORABLE 
ENVIRONMENT UNDER AN UPPER LEVEL RIDGE AXIS WITH WEAK TO MODERATE 
VERTICAL SHEAR. TC 28S IS NOT EXPECTED TO SIGNIFICANTLY INTENSIFY 
BUT TO REMAIN AT WARNING CRITERIA AND TRACK WESTWARD TO MADAGASCAR

REMARKS:
080900Z7 POSITION NEAR 19.3S3 49.4E7.
TROPICAL CYCLONE (TC) 28S (MANOU), LOCATED APPROXIMATELY 40 NM
FROM THE EAST COAST OF MADAGASCAR, HAS TRACKED WEST-SOUTHWESTWARD AT
08 KNOTS IN THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON
080530Z6 MULTISPECTRAL SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 65 AND 77 KNOTS.
VISIBLE IMAGERY INDICATES THAT TC 28S HAS FORMED A SMALL BANDING
EYE. THE SYSTEM IS EXPECTED TO CONTINUE TRACKING WEST-SOUTHWESTWARD
UNDER THE INFLUENCE OF A MID-LEVEL RIDGE TO THE EAST BEFORE MAKING
LANDFALL ON MADAGASCAR. TC 28S SHOULD INTENSIFY SLIGHTLY PRIOR TO
LANDFALL WITHIN THE NEXT 12 HOURS, AND IS THEN EXPECTED TO WEAKEN
OVER LAND AS IT TRACKS SOUTH ALONG THE COAST BEFORE EXITING AND
REINTENSIFYING IN THE SOUTH INDIAN OCEAN. THE AVAILABLE DYNAMIC AIDS
CONSISTING OF NOGAPS, GFDN, AFWA MM5, NCEP AVIATION, AND UKMET EGRR
ARE IN REASONABLE AGREEMENT WITH THE EXCEPTION OF NOGAPS WHICH
DISSIPATES THE SYSTEM ON LAND AFTER 24 HOURS. OUR FORECAST IS BASED
ON A CONSENSUS OF THE AVAILABLE AIDS. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 080600Z4 IS 21 FEET. NEXT WARNINGS AT 082100Z1 AND
090900Z8. RELEASED BY CAPT KENDALL, USAF.//

REMARKS:
082100Z1 POSITION NEAR 19.5S5 49.1E4.
TROPICAL CYCLONE (TC) 28S (MANOU), LOCATED APPROXIMATELY 10 NM
FROM THE EAST COAST OF MADAGASCAR, HAS TRACKED WEST-SOUTHWESTWARD AT
02 KNOTS IN THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON
081730Z9 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 75 AND 90
KNOTS. INFRARED IMAGERY INDICATES THAT A 24 NM DIAMETER EYE
CONTINUES TO PERSIST AND HAS BECOME MORE IRREGULAR. THE SYSTEM IS
EXPECTED TO TRANSITION FROM WEST-SOUTHWESTWARD TO A MORE POLEWARD
TRACK TO THE SOUTH. A TRANSITORY ANTICYCLONE SOUTHWEST OF TC 28S
WILL MOVE EASTWARD UNDER THE STEERING ANTICYCLONE TO THE EAST OF TC
28S AND MERGE. THIS MERGING OF THE TWO ANTICYCLONES WILL CREATE A
POLEWARD STEERING ENVIRONMENT AT THE SAME TIME AS TC 28S IS MAKING
LANDFALL ON MADAGASCAR. TC 28S SHOULD MAKE LANDFALL IN THE NEXT 6 TO
12 HOURS AND THEN WEAKEN AS IT TRACKS SOUTH ALONG THE COAST BEFORE
EXITING IN THE SOUTH INDIAN OCEAN AND THEN SLOWLY REINTENSIFIES. THE
AVAILABLE DYNAMIC AIDS CONSISTING OF NOGAPS, GFDN, AFWA MM5, NCEP

REMARKS:
100900Z0 POSITION NEAR 21.4S7 49.0E3.
TROPICAL CYCLONE (TC) 28S (MANOU), LOCATED APPROXIMATELY 25 NM FROM
THE EAST COAST OF MADAGASCAR, HAS TRACKED SOUTHWARD AT 05 KNOTS OVER
THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON 100530Z9 MULTI-
SPECTRAL SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 35 AND 55 KNOTS. TC 28S
CONTINUES TO TRACK SLOWLY POLEWARD ALONG THE WESTERN PERIPHERY OF
THE MID TO LOW LEVEL RIDGE EAST OF THE SYSTEM. TC 28S IS FORECAST TO
MAINTAIN INTENSITY EARLY IN THE PERIOD, BUT DUE TO DRY AIR
ENTRAINMENT AND AN EQUATORWARD SHIFT OF THE UPPER LEVEL RIDGE AXIS,
THE SYSTEM SHOULD DISSIPATE BY THE END OF THE PERIOD. ALL MODELS
HAVE TROUBLE INITIALIZING ON THE SYSTEM, BUT THEY ALL SHOW A GENERAL
SOUTH THEN SOUTHEASTWARD MOTION THROUGH 48 HOURS. THE FORECAST TRACK
IS BASED ON A BLEND OF PERSISTENCE AND FIELD ANALYSIS OF NOGAPS,
GFS, AND GFDN. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 100600Z7 IS 15
FEET. NEXT WARNINGS AT 102100Z4 AND 110900Z1. RELEASED BY CAPT
VILPORS, USAF.//

REMARKS:
102100Z4 POSITION NEAR 22.7S1 48.8E0.
TROPICAL CYCLONE (TC) 28S (MANOU), LOCATED APPROXIMATELY 40 NM FROM
THE EAST COAST OF MADAGASCAR, HAS TRACKED SOUTHWARD AT 07 KNOTS OVER
THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON 101730Z2
ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND 35 KNOTS. TC 28S
CONTINUES TO ENTRAIN DRY AIR WHILE TRACKING SOUTHWARD VERY CLOSE TO
THE MADAGASCAR EAST COAST. THE SYSTEM HAS LOST ALMOST ALL DEEP
CONVECTION, AND A LOW LEVEL CIRCULATION CENTER (LLCC) IS NOW
DIFFICULT TO LOCATE. MODELS CONTINUE TO HAVE TROUBLE INITIALIZING
THE SYSTEM. THE FORECAST TRACK TO THE SOUTH-SOUTHEAST IS BASED ON
PERSISTENCE AND ANALYSIS OF NOGAPS, GFDN, NCEP GFS, AND UKMET EGRR
FIELDS SHOWING A WEAKNESS IN THE PERIPHERAL RIDGE BEHIND A PASSING
SHORTWAVE TROUGH. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 101800Z0 IS 10
FEET. 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. RELEASED BY LT INGRAM, USN.//
