REMARKS:
080300Z1 POSITION NEAR 11.2S4 70.0E7.
TROPICAL CYCLONE (TC) 09S, LOCATED APPROXIMATELY 260 NM SOUTHWEST OF
DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT 02 KNOTS DURING THE
PAST SIX HOURS. THE WARNING POSITION IS BASED ON 072330Z5 ENHANCED
INFRARED AND RECENT MICROWAVE SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 35
KNOTS. ANIMATED SATELLITE IMAGERY INDICATES CYCLIC DEEP CONVECTION
HAS INCREASED, AND HAS BEGUN TO WRAP INTO THE LOW-LEVEL CIRCULATION
CENTER (LLCC). UPPER-LEVEL ANALYSIS REVEALS FAVORABLE DIFFLUENCE
ALOFT, AND VERTICAL WIND SHEAR OVER THE SYSTEM IS MINIMAL. TC 09S IS
FORECAST TO INTENSIFY AT A CLIMATOLOGICAL RATE INITIALLY, THEN MORE
SLOWLY AS THE SYSTEM ENTERS INCREASING VERTICAL WIND SHEAR TOWARD
THE END OF THE FORECAST PERIOD. AVAILABLE DYNAMIC AIDS CONSISTING OF
NGPS, NCEP AVIATION (AVN), UK MET OFFICE (EGRR), AND BETA ADVECTION
MODELS ARE IN GOOD AGREEMENT WITH THIS SCENARIO. THIS FORECAST IS
BASED ON PERSISTENCE AND A CONSENSUS OF THE AVAILABLE DYNAMIC AIDS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 080000Z8 IS 14 FEET. THIS WARNING

SATELLITE CURRENT INTENSITY ESTIMATES OF 45 TO 50 KNOTS. ANIMATED
SATELLITE IMAGERY INDICATES DEEP CONVECTION HAS INCREASED, AND

TC 09S WILL TRACK SOUTHWARD IN RESPONSE TO MID-LEVEL STEERING
ASSOCIATED WITH THE SUBTROPICAL RIDGE TO THE EAST OF TC 09S AND A
FILLING MID-LEVEL TROUGH TO THE SOUTHWEST. BY 24 HOURS TC 09S WILL
TURN SOUTH-SOUTHWESTWARD IN RESPONSE TO STEERING FLOW ASSOCIATED
WITH A MID-LEVEL RIDGE DEVELOPING TO THE SOUTHEAST ALONG 30 SOUTH.

REMARKS:
110300Z5 POSITION NEAR 24.0S6 70.2E9.
TROPICAL CYCLONE (TC) 09S (EBULA), LOCATED APPROXIMATELY 970 NM
SOUTH OF DIEGO GARCIA, HAS TRACKED SOUTH-SOUTHEASTWARD AT 15 KNOTS
DURING THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON 102330Z9
ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 55 AND 65 KNOTS.
ANIMATED WATER VAPOR SATELLITE IMAGERY INDICATES DRY AIR ENTRAINMENT
WRAPPING IN FROM WEST OF THE SYSTEM, WITH SHEARING ALSO
INDICATED IN THE NORTHERN SEMICIRCLE. TC 09S IS EXPECTED TO TRACK
GENERALLY SOUTH-SOUTHEASTWARD THROUGH 24 HOURS AND THEN TURN MORE
SOUTHEASTWARD IN RESPONSE TO A MID-LATITUDE FRONTAL SYSTEM
APPROACHING FROM THE SOUTHWEST. TC 09S IS FORECAST TO WEAKEN
THROUGHOUT THE PERIOD, AND WILL BEGIN THE TRANSITION TO AN
EXTRATROPICAL SYSTEM IN 12 HOURS, COMPLETING THE TRANSITION BY THE
END OF THE FORECAST PERIOD. THE AVAILABLE DYNAMIC AIDS, CONSISTING
OF NGPS, GFDN, UK MET OFFICE (EGRR), AND BETA ADVECTION MODELS ARE
IN GOOD AGREEMENT WITH THIS SCENARIO. AFWA MM5 AND NCEP AVIATION
(AVN) WEAKEN AND DISSIPATE THE SYSTEM, RATHER THAN COMPLETING
EXTRATROPICAL TRANSITION. THIS FORECAST IS BASED ON PERSISTENCE AND
A CONSENSUS OF NGPS, GFDN, EGRR AND THE BETA ADVECTION MODELS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 110000Z2 IS 20 FEET. REFER TO
WWIO30 RJTX FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS AT
111500Z8 AND 120300Z6.//

REMARKS:
111500Z8 POSITION NEAR 26.2S0 69.8E3.
TROPICAL CYCLONE (TC) 09S (EBULA), LOCATED IN THE CENTRAL SOUTHERN
INDIAN OCEAN, HAS TRACKED SOUTHWARD AT 08 KNOTS DURING THE PAST SIX
HOURS. THE WARNING POSITION IS BASED ON 111130Z7 ANIMATED SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 45 TO 55 KNOTS. ANIMATED SATELLITE IMAGERY
INDICATES THE CONVECTION IS BEING SHEARED OFF TO THE SOUTH OF THE
LOW LEVEL CIRCULATION CENTER (LLCC). TC 09S IS EXPECTED TO TRACK
INCREASINGLY SOUTH-SOUTHEASTWARD THROUGH THE FORECAST PERIOD. TC
09S IS FORECAST TO CONTINUE WEAKENING, AS IT MOVES INTO INCREASING
SHEAR WITH THE APPROACH OF A MID LATITUDE TROUGH. TC 09S IS
UNDERGOING EXTRATROPICAL TRANSITION AS INDICATED BY THE INTRUSION OF
DRY AIR WRAPPING IN FROM THE WEST. THE SYSTEM WILL COMPLETE
EXTRATROPICAL TRANSITION WITHIN THE NEXT 12 HOURS. THE AVAILABLE
DYNAMIC AIDS, CONSISTING OF NGPS, GFDN, UK MET OFFICE (EGRR), AND
BETA ADVECTION MODELS ARE IN GOOD AGREEMENT WITH THIS SCENARIO. THE
FORECAST IS BASED ON PERSISTENCE AND A CONSENSUS OF NGPS, GFDN,
EGRR, AND THE BETA ADVECTION MODELS. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 111200Z5 IS 25 FEET. NEXT WARNINGS AT 120300Z6 AND 121500Z9.//

REMARKS:
120300Z6 POSITION NEAR 27.7S6 71.4E2.
TROPICAL CYCLONE (TC) 09S (EBULA), LOCATED IN THE CENTRAL SOUTHERN
INDIAN OCEAN, HAS TRACKED SOUTHEASTWARD AT 07 KNOTS DURING THE PAST
SIX HOURS. THE WARNING POSITION IS BASED ON 112330Z0 ENHANCED
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 45 KNOTS AND A RECENT
QUIKSCAT PASS. ANIMATED SATELLITE IMAGERY INDICATES THE LOW LEVEL
CIRCULATION CENTER (LLCC) REMAINS PARTIALLY EXPOSED WITH THE DEEP
CONVECTION PRIMARILY IN THE SOUTHERN SEMICIRCLE. DRY AIR ENTRAINMENT
HAS CONTINUED WRAPPING IN FROM THE WEST. TC 09S IS EXPECTED TO TRACK
SOUTHEASTWARD AS IT COMPLETES EXTRATROPICAL TRANSITION. THE SYSTEM
WILL COMPLETE EXTRATROPICAL TRANSITION WITHIN THE NEXT FEW HOURS.
THE AVAILABLE DYNAMIC AIDS, CONSISTING OF NGPS, GFDN, UK MET OFFICE
(EGRR), NCEP AVIATION (AVN) AND THE BETA ADVECTION MODELS ARE IN
GOOD AGREEMENT WITH THIS SCENARIO. THE FORECAST IS BASED ON
PERSISTENCE AND A CONSENSUS OF ALL THE AVAILABLE DYNAMIC AIDS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 120000Z3 IS 20 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.//
