1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 08JUN23 1800Z, TROPICAL CYCLONE 02A (BIPARJOY) WAS LOCATED 
NEAR 14.4N 66.2E, APPROXIMATELY 556 NM SOUTHEAST OF MASIRAH ISLAND, AND 
HAD TRACKED NORTHEASTWARD AT 03 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 75 KNOTS GUSTING TO 90 KNOTS. 
SEE REF A (WTIO31 PGTW 082100) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 93B) HAS PERSISTED NEAR 19.8N 
91.2E, APPROXIMATELY 224 NM SOUTHEAST OF KOLKATA, INDIA. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY AND A 082305Z SSMIS 91GHZ MICROWAVE 
IMAGE DEPICT A CONSOLIDATED AREA LLCC OBSCURED BY FLARING CONVECTION THAT 
IS BEING SHEARED TO THE SOUTHWEST. FURTHERMORE, A 081525Z ASCAT-B IMAGE 
FURTHER EMPHASIZES THE CONSOLIDATED NATURE OF 93B WITH 25-30 KNOT WIND 
BARBS DENOTED IN THE CENTER. UPPER-LEVEL ANALYSIS INDICATES 93B IS IN A 
FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH LOW TO MODERATE (10-20 KNOT) 
VWS OFFSET BY GOOD DIVERGENCE ALOFT AND WARM (28-30C) SEA SURFACE 
TEMPERATURES. GLOBAL MODELS ARE IN AGREEMENT THAT 93B WILL CONTINUE TO 
TRACK GENERALLY NORTHEASTWARD AND THOUGH OVERALL CONDITIONS ARE 
FAVORABLE, LAND INTERACTION WILL SERVE TO LIMIT THE POTENTIAL 
DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 998 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS IS MEDIUM.
      (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: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: ADDED MEDIUM AREA IN PARA 1.B.(1)//
