TROPICAL DISTURBANCE SUMMARY:\r\n      (1) AN AREA OF CONVECTION (INVEST 99B) HAS PERSISTED NEAR 12.5N \r\n81.0E, APPROXIMATELY 132 NM SOUTHEAST OF CHENNAI. ANIMATED ENHANCED \r\nINFRARED SATELLITE IMAGERY DEPICTS A HIGHLY BROAD CIRCULATION AREA \r\nOFFSHORE OF CHENNAI, INDIA WITH SPOTTY CONVECTION. A MID-LEVEL \r\nCIRCULATION IS OBSERVED DISPLACED 250 TO 300 NM EAST OF THE SURFACE \r\nCIRCULATION, INDICATING A DISORGANIZED SYSTEM. A 211523Z ASCAT PASS SHOWS \r\nA LARGE ELLIPTICAL AREA OF TURNING WITH AN ASYMMETRIC WIND FIELD, \r\nCONSISTING OF LIGHT EASTERLIES TO THE NORTH AND A MONSOONAL WESTERLY WIND \r\nBURST SOUTH OF SRI LANKA WITH 25-30 KT WINDS THAT ARE NOT DIRECTLY \r\nASSOCIATED WITH THE CIRCULATION AT THIS TIME. CURRENT ENVIRONMENTAL \r\nANALYSIS SHOWS FAVORABLE CONDITIONS WITH WEAK (<15 KNOTS) VERTICAL WIND \r\nSHEAR AND WARM (28-29C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN \r\nGOOD AGREEMENT THAT 99B WILL GET USHERED EASTWARD BY THE WESTERLY WIND \r\nBURST AND THEN HOOK NORTHWARD OVER THE EASTERN BAY OF BENGAL OVER THE \r\nNEXT 72 HOURS, GRADUALLY CONSOLIDATING INTO A MONSOON DEPRESSION. MAXIMUM \r\nSUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 18 KNOTS. MINIMUM SEA \r\nLEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. THE POTENTIAL FOR THE \r\nDEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS \r\nLOW.\r\n      (2) NO OTHER SUSPECT AREAS.\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE."
