1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 99B) PREVIOUSLY LOCATED NEAR 
12.5N 81.0E IS NOW LOCATED NEAR 14.0N 83.6E, APPROXIMATELY 204 NM EAST-
NORTHEAST OF CHENNAI. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY 
DEPICTS A HIGHLY BROAD CIRCULATION AREA OFFSHORE OF CHENNAI, INDIA WITH 
SPOTTY CONVECTION. A MID-LEVEL CIRCULATION IS OBSERVED DISPLACED 250 TO 
300 NM EAST OF THE SURFACE CIRCULATION, INDICATING A DISORGANIZED 
SYSTEM. A 211523Z ASCAT PASS SHOWS A LARGE ELLIPTICAL AREA OF TURNING 
WITH AN ASYMMETRIC WIND FIELD, CONSISTING OF LIGHT EASTERLIES TO THE 
NORTH AND A MONSOONAL WESTERLY WIND BURST SOUTH OF SRI LANKA WITH 25-30 
KT WINDS THAT ARE NOT DIRECTLY ASSOCIATED WITH THE CIRCULATION AT THIS 
TIME. CURRENT ENVIRONMENTAL ANALYSIS SHOWS FAVORABLE CONDITIONS WITH 
WEAK (<15 KNOTS) VERTICAL WIND SHEAR AND WARM (28-29C) SEA SURFACE 
TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 99B WILL GET 
USHERED EASTWARD BY THE WESTERLY WIND BURST AND THEN HOOK NORTHWARD 
OVER THE EASTERN BAY OF BENGAL OVER THE NEXT 72 HOURS, GRADUALLY 
CONSOLIDATING INTO A MONSOON DEPRESSION. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 15 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1003 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 22MAY24 1200Z, TROPICAL CYCLONE 24S (IALY) WAS LOCATED 
NEAR 3.1S 41.8E, APPROXIMATELY 268 NM NORTHEAST OF DAR ES SALAAM, 
TANZANIA, AND HAD TRACKED NORTH- NORTHWESTWARD AT 03 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 
KNOTS GUSTING TO 40 KNOTS. SEE REF A (WTXS31 PGTW 221500) FOR THE FINAL 
WARNING ON THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
