REMARKS:
100300Z4 POSITION NEAR 17.9S7 70.9E6
TROPICAL CYCLONE (TC) 09S (EBULA), LOCATED APPROXIMATELY 600 NM
SOUTH OF DIEGO GARCIA, HAS TRACKED SOUTH-SOUTHWEST AT 08 KNOTS
DURING THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON 092330Z7
ENHANCED INFRARED IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 65 KNOTS. ANIMATED INFRARED
SATELLITE IMAGERY INDICATES DEEP CONVECTION IS INCREASING OVER THE
LOW LEVEL CIRCULATION CENTER. ANIMATED WATER VAPOR IMAGERY DEPICTS
POLEWARD OUTFLOW CONTINUES TO BE STRONG AHEAD OF A LONGWAVE TROUGH.
TC 09S IS EXPECTED TO TRACK SOUTH-SOUTHWEST OUT 24 HOURS AS A
MID-LEVEL SHORTWAVE RIDGE PASSES SOUTH OF SYSTEM. AFTERWARDS, TC 09S
WILL TURN SOUTHEAST AS THE MID-LEVEL RIDGE PROPAGATES PAST. TC 09S
IS FORECAST TO INTENSIFY AT A NEAR CLIMATOLOGICAL RATE FOR THE NEXT
12 HOURS, THEN SLOWLY WEAKEN AS IT ENCOUNTERS INCREASING VERTICAL
WIND SHEAR. THE AVAILABLE DYNAMIC AIDS, CONSISTING OF NGPS, GFDN,
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 100000Z1 IS 21 FEET. NEXT WARNINGS AT
101500Z7 AND 110300Z5.//
