REMARKS:
071500Z POSITION NEAR 9.3S 78.8E.
TROPICAL CYCLONE (TC) 03S (CLEO), LOCATED APPROXIMATELY 425 NM EAST-
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WESTWARD AT 11 KNOTS OVER THE
PAST SIX HOURS. CLEO HAS STRENGTHENED 10 KNOTS SINCE THE PREVIOUS
WARNING. LOW VERTICAL WIND SHEAR, HIGH OCEAN HEAT CONTENT, AND
FAVORABLE POLEWARD VENTING HAVE ALL FACILITATED THIS INTENSIFICATION.
AS OF 071200Z, PGTW AND FMEE ARE REPORTING A DVORAK CURRENT
INTENSITY OF 3.0, WHICH IS EQUIVALENT TO 45 KNOTS. THE CYCLONE IS
FORECAST TO CONTINUE TO INTENSIFY AS IT TRACKS GENERALLY WESTWARD
ALONG THE NORTHERN PORTION OF THE MID-LEVEL SUBTROPICAL STEERING
RIDGE TO THE SOUTH. BEYOND TAU 48 THE SYSTEM WILL BEGIN TO SLOW IN
RESPONSE TO A WEAKENING RIDGE, AND INTENSITIES WILL BEGIN TO STEADY
AROUND 70 KNOTS IN ACCORDANCE WITH THE LATEST AVAILABLE INTENSITY
GUIDANCE. THIS FORECAST HAS BEEN SLOWED FROM THE PREVIOUS FORECAST
BETWEEN TAU 72 AND TAU 120 TO ACCOUNT FOR A SLOWER MODEL CONSENSUS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 071200Z IS 13 FEET. NEXT WARNINGS
AT 080300Z AND 081500Z.//

2.B OTHER INFORMATIONS:
T=CI=3.5-

THE LAST MW IMAGERY F16 07 1353Z SHOWS AN IMPROVING ASPECT OF THE SYSTEM
AS AN EYE STARTS TO FORM. IR IMAGERIES SHOW A CURVED BAND PATTERN LEADING
TO A DT ABOUT 3.5.

ACCORDING TO CIMSS DATA, SYSTEM IS NOW IN PHASIS WITH AN UPPER LEVEL
RIDGE AND THE WINDSHEAR IS WEAK. WV ANIMATED IMAGERY SHOWS THAT UPPER
LEVEL DIVERGENCE REMAINS FAIRLY GOOD OVER THE SYSTEM. IT REMAINS THE BEST
OVER THE SOUTHERN SEMI-CIRCLE, SPECIALLY OVER THE SOUTHWESTERN QUADRANT.
ACCORDING TO O
CEAN HEAT CONTAIN (OHC) DATA FROM RAMMB/NOAA/CIRA, SYSTEM IS CURRENTLY
LOCATED NEAR AN AREA OF HIGH OHC. UNDERGOING GOOD ENVIRONMENTAL
CONDITIONS, SYSTEM SHOULD NOW INTENSIFY AT A CLIMATOLOGICAL RATE FOR THE
NEXT 24 HOURS. AT 36/48 HOURS, AS THE SYSTEM MOVES AWAY FROM THIS HIGH
OHC AREA, THE INTENS
IFICATION RATE HAS BEEN LOWERED BUT ONE SHOULD NOTE THAT UPPER LEVEL
CONDITIONS REMAIN FAVOURABLE ...

THE SYSTEM NOW TRACKS MORE WESTSOUTHWESTWARDS ON THE NORTHWESTERN EDGE A
THE SLIGHTLY WEAKENING SUBTROPICAL RIDGE LOCATED IN THE SOUTHEAST.
AVAILABLE NWP REMAIN IN GOOD AGREEMENT WITH MAINTAINING THIS GENERAL
MOTION FOR THE NEXT 24 HOURS. THEREAFTER, MID-LEVEL STEERING FLOWS ARE
WEAKER AND STORM MOT
ION SHOULD DECREASE.
THE FORECAST IS BASED ON A CONSENSUS OF THE AVAILABLE MODELS.

REMARKS:
080300Z POSITION NEAR 10.1S 77.1E.
TROPICAL CYCLONE (TC) 03S (CLEO), LOCATED APPROXIMATELY 340 NM EAST-
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT 09 KNOTS
OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS
THAT CONVECTION HAS CONTINUED TO INCREASE IN THE SOUTHERN HALF OF
TC 03S. THE POLEWARD OUTFLOW FROM TC 03S HAS FUELED THE 10 KNOT
INCREASE IN INTENSITY OVER THE PAST 12 HOURS. FIXES FROM PGTW AND
KNES WERE AT 3.5 WITH FMEE AT A 4.0. THE CURRENT INTENSITY OF 55
KNOTS FAVORS PGTW AND KNES. A RECENT 080004Z SSMIS MICROWAVE PASS
SHOWS AN EYE HAS STARTED TO DEVELOP. IT ALSO SHOWS THAT THE DEEPEST
CONVECTION HAS PERSISTED IN THE BANDING LOCATED IN THE SOUTHERN HALF
OF THE SYSTEM. UPPER LEVEL ANALYSIS CONTINUES TO SHOW THE STRONG
POLEWARD OUTFLOW WITH AN UPPER LEVEL POINT SOURCE ANTICYCLONE LOCATED
OVER THE LLCC. THE TRACK HAS SHIFTED TO A MORE WEST-SOUTHWESTWARD
TRACK THAN PREVIOUSLY FORECAST, AND IS LIKELY DUE TO THE QUICKER
BREAKDOWN OF THE SUBTROPICAL RIDGE BY A TRANSITORY MID-LATITUDE
TROUGH, CURRENTLY LOCATED TO THE SOUTHWEST OF TC 03S. TRACK SPEEDS
WILL SLOWLY DECREASE THROUGHOUT THE FORECAST AS THE STEERING RIDGE
CONTINUES TO WEAKEN AS A SERIES OF TROUGHS ARE FORECAST TO PASS TO
THE SOUTH OF TC 03S. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 080000Z IS
14 FEET. NEXT WARNINGS AT 081500Z AND 090300Z.//
