REMARKS:
022100Z5 POSITION NEAR 13.5S9  86.1E5.
THE FAIR SUSPECT AREA PREVIOUSLY LOCATED NEAR 13.2S6 86.4E8
HAS RAPIDLY DEVELOPED INTO TROPICAL CYCLONE (TC) 16S ABOUT 900 NM
SOUTHEAST OF DIEGO GARCIA ISLAND. THIS IS A VERY COMPACT SYSTEM AND
DVORAK INTENSITY CLASSIFICATIONS MAY NOT BE REPRESENTATIVE OF THE
ACTUAL STRENGTH. HOWEVER, A MICROWAVE IMAGE SUGGESTS THAT A BANDING
EYE FEATURE MAY BE DEVELOPING. TC 16S IS EXPECTED TO TRACK IN A
GENERAL WEST-SOUTHWESTERLY DIRECTION TOWARD A WEAKNESS IN THE
SUBTROPICAL RIDGE. THIS FORECAST SCENARIO IS CONSISTENT WITH THE
BETA ADVECTION MODELS, CLIPER AND HPAC. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 021800Z1 IS 12 FEET. NEXT WARNINGS AT 030900Z2 AND
032100Z6.//

REMARKS:
030900Z2 POSITION NEAR 13.8S2 83.8E9.
TROPICAL CYCLONE (TC) 16S HAS TRACKED WEST-SOUTHWEST AT 11 KTS IN
THE PAST 6 HOURS AND IS CURRENTLY APPROXIMATELY 800 NM EAST-
SOUTHEAST OF DIEGO GARCIA ISLAND. THE WARNING POSITION IS BASED UPON
ANIMATED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
UPON CURRENT INTENSITY ESTIMATES OF 30 KNOTS AND SYNOPTIC DATA. A
RECENT SPECIAL SENSOR MICROWAVE IMAGER (SSM/I) PASS REVEALED A
COMPACT LOW-LEVEL CIRCULATION CENTER (LLCC) AND DEEP CONVECTION
OVERHEAD. TC 16S IS EXPECTED TO TRACK IN A WEST-SOUTHWESTERLY
DIRECTION TOWARD A WEAKNESS IN THE SUBTROPICAL RIDGE. TC 16S IS
EXPECTED TO INTENSIFY AT A CLIMATOLOGICAL RATE THROUGH 48 HOURS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 030600Z9 IS 12 FEET. NEXT
WARNINGS AT 032100Z6 AND 040900Z3. REFER TO TROPICAL CYCLONE 17S
(WALTER) WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES.//

REMARKS:
042100Z7 POSITION NEAR 14.8S3 77.2E6.
TROPICAL CYCLONE (TC) 16S, LOCATED APPROXIMATELY 550 NM SOUTHEAST
OF DIEGO GARICA, HAS TRACKED WEST AT 11 KTS IN THE PAST 6 HOURS. THE
WARNING POSITION IS BASED UPON 041730Z5 INFRARED SATELLITE IMAGERY.
THE WARNING INTENSITY IS BASED UPON SATELLITE CURRENT INTENSITY
ESTIMATES OF 35 KNOTS. VISIBLE AND ENHANCED INFRARED ANIMATION
DEPICT A SUDDEN BURST OF DEEP CONVECTION OVER THE LOW-LEVEL
CIRCULATION CENTER. ANIMATION ALSO REVEALS DIRECT INTERACTION
(FUJIWHARA) WITH THE FAIR SUSPECT AREA TO THE NORTHEAST. THIS HAS
CAUSED A MORE WEST-NORTHWESTWARD TRACK DURING THE PAST 12 HOURS.
WATER VAPOR AND 200 MB ANAL INDICATE THAT THE SYSTEM IS BENEATH THE
SUBTROPICAL RIDGE AXIS. TC 16S SHOULD CONTINUE ON A WEST-
NORTHWESTWARD TRACK THROUGH THE PERIOD. THE SYSTEM IS FORECAST TO
INTENSIFY OVER THE FORECAST PERIOD AS THE SYSTEM REMAINS BENEATH THE
RIDGE. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 041800Z3 IS 12 FEET.
NEXT WARNINGS AT 050900Z4 AND 052100Z8. REFER TO TROPICAL CYCLONE 17S
(WALTER) WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES. REFER TO
TROPICAL CYCLONE 18S (NONAME) WARNINGS (WTXS33 PGTW) FOR TWELVE-

REMARKS:
050900Z4 POSITION NEAR 12.8S1  76.8E1.
TROPICAL CYCLONE (TC) 16S, LOCATED APPROXIMATELY 425 NM SOUTHEAST 
OF DIEGO GARCIA, WAS RELOCATED 120 NM TO THE NORTHWEST BASED ON 
VISIBLE IMAGERY REVEALING AN EXPOSED LOW-LEVEL CIRCULATION CENTER 
(LLCC). THE WARNING POSITION IS BASED UPON 050530Z3 VISIBLE AND 
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED UPON 
SATELLITE CURRENT INTENSITY ESTIMATES OF 35 KNOTS. VISIBLE AND 
ENHANCED INFRARED ANIMATION INDICATE THE SYSTEM IS DIRECTLY 
INTERACTING WITH A WEAK CIRCULATION TO THE NORTHEAST IN A POSSIBLE 
FUJIWHARA CIRCULATION. THIS HAS CAUSED A MORE NORTH-NORTHWESTWARD 
TRACK DURING THE PAST 12 HOURS. ANIMATED WATER VAPOR IMAGERY SHOWS 
SOME DRY AIR WRAPPING INTO THE GENERAL CIRCULATION INHIBITING 
FURTHER DEVELOPMENT. THE 200 MB ANALYSIS INDICATES THAT THE SYSTEM 
IS BENEATH THE SUBTROPICAL RIDGE AXIS. TC 16S SHOULD CONTINUE ON A 
WEST-NORTHWESTWARD AND THEN MORE WESTWARD AS IT BREAKS FROM THE 
DIRECT INTERACTION. THE SYSTEM IS FORECAST TO INTENSIFY SLOWLY OVER 
THE FORECAST PERIOD AS THE SYSTEM REMAINS BENEATH THE RIDGE.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 050600Z1 IS 12 FEET. NEXT 
WARNINGS AT 052100Z8 AND 060900Z5. REFER TO TROPICAL CYCLONE 17S 
(WALTER) WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES.

052100Z8 POSITION NEAR 10.8S9 78.4E9.
TROPICAL CYCLONE (TC) 16S, LOCATED APPROXIMATELY 395 NM SOUTHEAST
OF DIEGO GARCIA, WAS TRACKING NORTHEASTWARD AT 11 KNOTS OVER THE
LAST 06 HOURS. THE WARNING POSITION IS BASED UPON 051730Z6 INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED UPON SATELLITE
CURRENT INTENSITY ESTIMATES OF 25 KNOTS. ANIMATED SATELLITE IMAGERY
INDICATES THE SYSTEM HAS DISSAPATED OVER THE PAST 12 HOURS. THE
REMNANTS OF THE SYSTEM CONTINUES TO INTERACT WITH A WEAK CIRCULATION
TO THE EAST IN A FUJIWHARA CIRCULATION. THE REMNANTS ARE FORECAST TO
TRACK TO THE NORTHEAST OVER THE NEXT 12 HOURS AND MERGE WITH THE
SYSTEM TO THE EAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 051800Z4 IS
10 FEET. REFER TO TROPICAL CYCLONE 17S (WALTER) WARNINGS (WTXS32
