REMARKS:
091500Z5 POSITION NEAR 16.3S0 71.4E2.
TROPICAL CYCLONE (TC) 09S (EBULA), LOCATED APPROXIMATELY 510 NM
SOUTH OF DIEGO GARCIA, HAS TRACKED SOUTH-SOUTHEASTWARD AT 08 KNOTS
DURING THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON 091130Z4
ENHANCED INFRARED AND MULTISPECTRAL SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 45 TO
55 KNOTS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY INDICATES DEEP
CONVECTION HAS INCREASED OVER THE LOW LEVEL CIRCULATION CENTER.
WATER VAPOR IMAGERY DEPICTS A WELL-DEVELOPED POLEWARD OUTFLOW
CHANNEL. TC 09S IS EXPECTED TO TRACK GENERALLY SOUTHWARD THROUGH 24
TO 36 HOURS AS A MID-LEVEL SHORTWAVE RIDGE PASSES SOUTH OF SYSTEM.
AFTER 36 HOURS, TC 09S WILL TURN SOUTH-SOUTHWESTWARD AS THE MID-
LEVEL RIDGE CONTINUES TO PROPAGATE EASTWARD. TC 09S IS FORECAST TO
INTENSIFY AT A NEAR CLIMATOLOGICAL RATE FOR THE NEXT 36 HOURS, THEN
SLOWLY WEAKEN AS IT ENCOUNTERS INCREASING VERTICAL WIND SHEAR. THE
AVAILABLE DYNAMIC AIDS, CONSISTING OF NGPS, GFDN, AFWA MM5, NCEP
AVIATION (AVN), UK MET OFFICE (EGRR), AND BETA ADVECTION MODELS ARE
IN FAIR AGREEMENT WITH THIS SCENARIO. THIS FORECAST IS BASED ON
PERSISTENCE AND A CONSENSUS OF THE AVAILABLE DYNAMIC AIDS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 091200Z2 IS 21 FEET. NEXT WARNINGS AT
100300Z4 AND 101500Z7.//
