      (1) THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED
NEAR 7.8S 56.5E, IS NOW LOCATED NEAR 7.2S 55.0E, APPROXIMATELY 790
NM NORTH-NORTHWEST OF MAURITIUS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS FLARING CONVECTION WRAPPING INTO A BROAD,
CONSOLIDATING LLC. A 04201523Z PARTIAL SSMIS 91GHZ MICROWAVE IMAGE
REVEALS ISOLATED AREAS OF DEEP CONVECTION AND FORMATIVE BANDING. THE
CURRENT UPPER LEVEL ENVIRONMENT IS CHARACTERIZED BY MARGINAL
DIFFLUENCE ALOFT AND LOW TO MODERATE (10-20 KTS) VERTICAL WIND
SHEAR. SSTS ARE WARM (28-29C) AND WILL SUPPORT FURTHER DEVELOPMENT.
GLOBAL MODELS ARE SPLIT ON THE CHANCE OF DEVELOPMENT, WITH NAVGEM
AND GFS PREDICTING DEVELOPMENT AS THE SYSTEM TRACKS SOUTHWEST
TOWARDS MADAGASCAR OVER THE NEXT SEVERAL DAYS, WHILE THE UKMET MODEL
DOES NOT FORECAST SIGNIFICANT INTENSIFICATION AT THIS TIME. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO MEDIUM.

2. REMARKS: THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED
NEAR 8.1S 51.9E IS NOW LOCATED NEAR 10.1S 50.6E, APPROXIMATELY 705
NM NORTH-NORTHWEST OF LA REUNION. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY REVEALS A PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER
(LLCC) WITH THE MAJORITY OF THE CONVECTION LOCATED IN THE SOUTHERN
PERIPHERY. A 220252Z SSMIS 91GHZ MICROWAVE IMAGE ALSO DEPICTS THE
DEEP CONVECTION ORGANIZING TO THE SOUTH OF THE LLCC AND BEGINNING TO
WRAP INTO THE CENTER. UPPER LEVEL ANALYSIS SHOWS THAT THE SYSTEM IS
LOCATED IN AN AREA OF FAVORABLE (10-15 KNOTS) VERTICAL WIND SHEAR
WITH DISTINCT POLEWARD OUTFLOW WHICH IS AIDING DEVELOPMENT.
ADDITIONALLY, WARM SEA SURFACE TEMPERATURES (28-29C) ARE SUPPORTIVE
OF DEVELOPMENT. GLOBAL MODELS ARE NOW IN GOOD AGREEMENT THAT THE
SYSTEM WILL INTENSIFY TO TROPICAL CYCLONE STRENGTH AT APPROXIMATELY
TAU 24 WITH THE SYSTEM PASSING ALONG THE EASTERN COASTLINE OF
MADAGASCAR AS IT TRANSITS ALONG A SOUTHWARD TRAJECTORY. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS HIGH.
