REMARKS:
080900Z POSITION NEAR 15.5S 55.1E.
TROPICAL CYCLONE (TC) 13S (GELENA), LOCATED APPROXIMATELY 329 NM
NORTH-NORTHWEST OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTHEASTWARD
AT 09 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS A SYMMETRIC SYSTEM WITH A WELL-DEFINED, 20 NM WIDE, EYE
FEATURE. THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE AND IS
BASED ON A 080600Z METEOSAT 8 VISIBLE IMAGE WHICH SHOWS THE EYE. THE
INITIAL INTENSITY OF 100 KNOTS IS BASED ON DVORAK CURRENT INTENSITY
ESTIMATES OF T5.5 (102 KNOTS) FROM PGTW AND KNES. TC 13S HAS RAPIDLY
INTENSIFIED OVER THE PAST SIX HOURS. ENVIRONMENTAL ANALYSIS SHOWS
THAT TC 13S HAS EXCELLENT POLEWARD AND EQUATORWARD OUTFLOW CHANNELS
WHICH HAS AIDED IN THE RAPID INTENSIFICATION. TC 13S IS ALSO
EXPERIENCING FAVORABLE VERTICAL WIND SHEAR (10 TO 15 KNOTS). SEA
SURFACE TEMPERATURES REMAIN FAVORABLE FOR DEVELOPMENT, BETWEEN 28 AND
29 DEGREES CELSIUS. TC 13S IS TRACKING SOUTHEASTWARD ALONG THE
WESTERN EDGE OF A SUBTROPICAL RIDGE (STR) LOCATED TO THE EAST. THE
STR WILL REMAIN THE DOMINANT STEERING FEATURE THROUGH TAU 96.
FAVORABLE UPPER LEVEL OUTFLOW AND SEA SURFACE TEMPERATURES WILL ALSO
ALLOW TC 13S TO CONTINUE TO RAPIDLY INTENSIFY, REACHING A PEAK OF 140
KNOTS BY TAU 24. AFTER TAU 24, TC 13S WILL GRADUALLY DECREASE IN
INTENSITY AS OUTFLOW BECOMES LESS FAVORABLE AND OCEAN HEAT CONTENT
BEGINS TO DECREASE. BY TAU 96, THE STR WILL WEAKEN AND ALLOW TC 13S
TO TRACK MORE EASTWARD. DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT,
INDICATING A SOUTHEASTWARD AND THEN EASTWARD TRACK. OVERALL, THERE IS
HIGH CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 080600Z IS 34 FEET. NEXT WARNINGS AT 081500Z, 082100Z,
090300Z AND 090900Z. REFER TO TROPICAL CYCLONE 12S (FUNANI) WARNINGS
(WTXS31 PGTW) FOR SIX-HOURLY UPDATES.//
