AMPN/REF IS TROPICAL CYCLONE FORMATION ALERT (WTPS21 PGTW 150730)//
RMKS/
1. IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT LOUIS
2. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
160 NM EITHER SIDE OF A LINE FROM 13.8S2 83.2E3 TO 15.2S8 76.7E0
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 20 TO 25 KNOTS. METSAT
IMAGERY AT 150830Z7 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 14.3S8 82.2E2. THE SYSTEM IS MOVING WEST-
SOUTHWESTWARD AT 08 KNOTS.
3. REMARKS:
ANIMATED VISIBLE AND INFRARED SATELLITE IMAGERY DEPICT A
SIGNIFICANT INCREASE IN AREAL COVERAGE OVER THE PAST 6 HOURS. A
150402Z2 SPECIAL SENSOR MICROWAVE IMAGER (SSM/I) PASS SHOWED THAT
THE STRONGER CONVECTION WAS CONFINED TO THE SOUTHERN HALF OF THE
SYSTEM. THE LOW-LEVEL CIRCULATION CENTER APPEARS TO BE ON THE
EASTERN EDGE OF THE CONVECTION. 200 MB ANALYSIS INDICATES THAT
THE UPPER-LEVEL RIDGE IS NOW SITUATED OVER THE SYSTEM. MAXIMUM
SUSTAINED WINDS ARE ESTIMATED TO BE AT 20 TO 25 KNOTS. MINIMUM
SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. THE POTENTIAL
FOR THE DEVELOPMENT OF A TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO GOOD.
4. THIS ALERT VALID UNTIL 161000Z8.

REMARKS:
152100Z9 POSITION NEAR 15.2S8 79.4E0.
THE AREA OF CONVECTION SOUTHEAST OF DIEGO GARCIA, WHICH WAS THE
SUBJECT OF A TROPICAL CYCLONE FORMATION ALERT (WTXS21 151000), HAS
DEVELOPED INTO TROPICAL CYCLONE 26S. TROPICAL CYCLONE (TC) 26S,
LOCATED APPROXIMATELY 640 NM SOUTHEAST OF DIEGO GARCIA HAS TRACKED
WEST-SOUTHWESTWARD AT 10 KNOTS DURING THE PAST 6 HOURS. THE WARNING
POSITION IS BASED ON 151730Z7 INFRARED SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 30 TO 45 KNOTS. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS
IMPROVED ORGANIZATION OVER THE PAST 8 HOURS WITH DEEP CONVECTION
WRAPPING AROUND THE LOW-LEVEL CIRCULATION CENTER (LLCC). IMAGERY
ALSO SHOWS THAT THE STRONGEST CONVECTION IS WEST AND SOUTH OF THE
LLCC. A 152028Z8 TROPICAL RAINFALL MEASURING MISSION PASS DEPICTS A
CONVECTIVE BAND SOUTHEAST TO WEST OF TC 26S WITH THE LLCC LOCATED
ABOUT 15 NM EAST OF THE DEEP CONVECTION. THE UW-CIMSS ANALYSIS AND
THE 200 MB ANALYSIS INDICATE THAT THE SYSTEM IS UNDER THE
SUBTROPICAL RIDGE AXIS WITH LIGHT TO MODERATE VERTICAL WIND SHEAR.
TC 26S IS FORECAST TO TRACK WESTWARD UNDER THE STEERING INFLUENCE OF
THE LOW TO MID-LEVEL SUBTROPICAL RIDGE SITUATED TO THE SOUTH. TC 26S
IS EXPECTED TO INTENSIFY AT A NEAR CLIMATOLOGICAL RATE THROUGH THE
FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 151800Z5 IS 14
FEET. THIS WARNING SUPERSEDES AND CANCELS NAVPACMETOCCEN 150951Z APR
00 TROPICAL CYCLONE FORMATION ALERT (WTXS21 PGTW 151000). NEXT

REMARKS:
160900Z6 POSITION NEAR 15.7S3 78.0E5.
TROPICAL CYCLONE (TC) 26S, LOCATED APPROXIMATELY 610 NM SOUTHEAST OF
DIEGO GARCIA HAS TRACKED WEST-SOUTHWESTWARD AT 08 KNOTS DURING THE
PAST 6 HOURS. THE WARNING POSITION IS BASED ON 160530Z5 INFRARED AND
VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 30 TO 45 KNOTS. A 160350Z5
SPECIAL SENSOR MICROWAVE IMAGER (SSM/I) PASS DEPICTED A DEVELOPED
CONVECTIVE BAND MOVING IN TOWARD THE LOW-LEVEL CIRCULATION CENTER
(LLCC) FROM THE SOUTHEAST. COMPARED TO EARLIER MICROWAVE PASSES,
DEEP CONVECTION HAS INCREASED OVER THE PAST 12 HOURS NEAR THE
EASTERN SIDE OF THE LLCC. ANIMATED VISIBLE IMAGERY SHOWS AN 85 NM
CENTRAL DENSE OVERCAST (CDO) EXTENDING OVER THE SYSTEM. MID-LEVEL
HIGH SITUATED NEAR 27.0S9 64.0E0 IS EXPECTED TO STEER TC 26S
GENERALLY WESTWARD THROUGH THE PERIOD. 200 MB ANALYSIS INDICATES
THAT THE SYSTEM HAS REMAINED UNDER THE SUBTROPICAL RIDGE AXIS. TC
26S IS EXPECTED TO INTENSIFY AT A CLIMATOLOGICAL RATE THROUGH THE
FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 160600Z3 IS 14
FEET. NEXT WARNINGS AT 162100Z0 (DTG 161953Z5) AND 170900Z7 (DTG

REMARKS:
182100Z2 POSITION NEAR 17.5S3 71.4E2.
TROPICAL CYCLONE (TC) 26S (INNOCENTE), HAS TRACKED WEST-
SOUTHWESTWARD AT 08 KNOTS DURING THE PAST 6 HOURS. THE WARNING
POSITION IS BASED ON 181730Z0 INFRARED SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE INTENSITY ESTIMATES OF 30 TO
45 KNOTS. RECENT MICROWAVE AND ANIMATED SATELLITE IMAGERY DEPICT A
BROAD LOW-LEVEL CIRCULATION CENTER (LLCC) WITH INTERMITTENT
CONVECTION BLOWING UP NEAR THE CENTER. 200 MB ANALYSIS INDICATES THE
SYSTEM REMAINS UNDER THE SUBTROPICAL RIDGE. TC 26S (INNOCENTE) IS
FORECAST TO TRACK INITIALLY WEST-SOUTHWESTWARD UNDER THE STEERING
INFLUENCE OF THE SUB TROPICAL LEVEL RIDGE SITUATED SOUTH OF THE
SYSTEM. THE TRACK WILL BECOME INCREASINGLY SOUTHWARD AS THE SYSTEM
MOVES INTO A WEAKNESS IN THE SUBTROPICAL RIDGE, CAUSED BY A PASSING
MID-LATITUDE SYSTEM TO THE SOUTH. TC 26S (INNOCENTE) IS EXPECTED TO
MAINTAIN INTENSITY THROUGH THE NEXT 24 HOURS, THEN BEGIN TO WEAKEN
AS IT MOVES INTO INCREASING VERTICAL WIND SHEAR. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 181800Z8 IS 16 FEET. NEXT WARNINGS AT 190900Z9 (DTG
190753Z5) AND 192100Z3 (DTG 191953Z8). REFER TO TROPICAL CYCLONE
24S (PAUL) WARNINGS (WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES. REFER
TO TROPICAL CYCLONE 27S (ROSITA) WARNINGS (WTXS33 PGTW) FOR TWELVE-
HOURLY UPDATES.//

REMARKS:
190900Z9 POSITION NEAR 18.1S0 69.9E4.
TROPICAL CYCLONE (TC) 26S (INNOCENTE), HAS TRACKED WESTWARD AT 08
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
190530Z8 VISIBLE AND INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 25
KNOTS. A 190450Z9 SPECIAL SENSOR MICROWAVE IMAGER PASS (SSMI) AND
ANIMATED SATELLITE IMAGERY DEPICT A FULLY EXPOSED BROAD LOW-LEVEL
CIRCULATION CENTER (LLCC) WITH NO ASSOCIATED CONVECTION. 200 MB
ANALYSIS INDICATES THE SYSTEM HAS MOVED SOUTH OF THE SUBTROPICAL
RIDGE AND IS EXPERIENCING INCREASING VERTICAL WIND SHEAR. THE SYSTEM
IS FORECAST TO TRACK WESTWARD OVER THE NEXT 12 HOURS UNDER THE
STEERING INFLUENCE OF THE LOW-LEVEL SUBTROPICAL RIDGE SITUATED SOUTH
OF THE SYSTEM. TC 26S (INNOCENTE) IS EXPECTED TO CONTINUE WEAKENING
DURING THE NEXT 12 HOURS AND DISSIPATE. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 190600Z6 IS 12 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. REFER TO
TROPICAL CYCLONE 24S (PAUL) WARNINGS (WTXS31 PGTW) FOR TWELVE-HOURLY
UPDATES. REFER TO TROPICAL CYCLONE 27S (ROSITA) WARNINGS (WTXS33
PGTW) FOR TWELVE-HOURLY UPDATES.//
