REMARKS:
090300Z2 POSITION NEAR 15.5S1 99.4E2.
TROPICAL CYCLONE (TC) 14S (FIONA), LOCATED APPROXIMATELY 260 NM
SOUTHEAST OF THE COCOS ISLANDS, HAS TRACKED SOUTHWESTWARD AT 11
KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
082330Z6 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 102 KNOTS.
SATELLITE IMAGERY DEPICTS TC 14S HAS A 15 NM IRREGULAR EYE AND
RECENT MICROWAVE IMAGERY REVEALS DRIER AIR TO THE SOUTH OF THE
SYSTEM. TC 14S IS FORECAST TO TRACK WEST-SOUTHWESTWARD THROUGHOUT
THE FORECAST PERIOD ALONG THE LOW TO MID-LEVEL SUBTROPICAL RIDGE
SOUTH OF THE SYSTEM. TC 14S IS FORECAST TO INTENSIFY ONLY SLIGHTLY
THROUGH 12 TO 24 HOURS AND IS EXPECTED TO WEAKEN SLOWLY AFTER 24
HOURS AS IT ENTERS A REGION OF DRIER AIR AND INCREASED VERTICAL WIND
SHEAR. ALL THE AVAILABLE DYNAMIC AIDS, INCLUDING NGPS, GFDN, UKMET
(EGRR), AFWA MM5 AND NCEP AVIATION (AVN) ARE IN GOOD AGREEMENT WITH
THIS SCENARIO. OUR FORECAST IS BASED ON PERSISTENCE AND A BLEND OF
ALL THE AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
090000Z9 IS 19 FEET. NEXT WARNINGS AT 091500Z5 AND 100300Z4. REFER
TO TROPICAL CYCLONE 16S (NONAME) WARNINGS (WTXS32 PGTW) FOR TWELVE-
HOURLY UPDATES.//
