1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   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:
      (1) THE AREA OF CONVECTION (INVEST 98S) PREVIOUSLY LOCATED 
NEAR 15.1S 111.0E IS NOW LOCATED NEAR 14.0S 111.9E, APPROXIMATELY 
422 NM EAST-SOUTHEAST OF CHRISTMAS ISLAND. ANIMATED MULTISPECTRAL 
SATELLITE IMAGERY DEPICTS CONVECTION PARTIALLY OBSCURING A LOW 
LEVEL CIRCULATION (LLC). A 290223Z PARTIAL ASCAT-B IMAGE REVEALS 
25KT WINDS OFFSET 200 NM TO THE SOUTH EAST OF THE LLC. ENVIRONMENTAL 
ANALYSIS INDICATES MARGINALLY FAVORABLE CONDITIONS FOR DEVELOPMENT 
WITH POLEWARD OUTFLOW ALOFT AND WARM (28-29C) SEA SURFACE 
TEMPERATURES, OFFSET BY LOW TO MODERATE (15-20KT) VERTICAL WIND 
SHEAR. GLOBAL MODELS ARE IN GOOD GENERAL AGREEMENT THAT INVEST 
98S WILL HAVE LITTLE TO NO DEVELOPMENT AS IT REMAINS QUASI-
STATIONARY BEFORE DISSIPATING AROUND TAU 48.  MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA LEVEL 
PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. IN VIEW OF THE UNFAVORABLE 
FORECAST FOR THIS SYSTEM, IT IS NO LONGER CONSIDERED SUSPECT FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS. SEE REF A (WTXS21 PGTW 290630) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: CANCELLED TROPICAL CYCLONE FORMATION 
ALERT FOR INVEST 98S.//
