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:
      (1) AT 08FEB22 0000Z, TROPICAL CYCLONE 08S (BATSIRAI) WAS 
LOCATED NEAR 26.8S 41.6E, APPROXIMATELY 286 NM SOUTH-SOUTHEAST OF 
EUROPA ISLAND, AND HAD TRACKED SOUTHWARD AT 12 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 50 
KNOTS GUSTING TO 65 KNOTS. SEE REF A (WTXS31 PGTW 080300) FOR 
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED 
NEAR 11.5S 105.4E IS NOW LOCATED NEAR 15.0S 105.6E, APPROXIMATELY 
203 NM SOUTH OF CHRISTMAS ISLAND. ANIMATED MULTISPECTRAL IMAGERY AND 
A 072335Z SSMIS 91GHZ IMAGE DEPICT A LOW LEVEL CIRCULATION (LLCC) 
WITH DEEP BANDING WRAPPING INTO THE LLCC. IN ADDITION, THERE IS 
BROAD, DEEP CONVECTION WITHIN THE CENTRAL AND NORTHERN PERIPHERIES 
OF THE SYSTEM. ENVIRONMENTAL ANALYSIS INDICATES FAVORABLE CONDITIONS 
FOR DEVELOPMENT TO INCLUDE FAIR POLEWARD OUTFLOW, LOW (10-15KT) 
VERTICAL WIND SHEAR, AND VERY WARM (29-30) SEA SURFACE TEMPERATURES. 
GLOBAL MODELS ARE IN AGREEMENT THAT THE INVEST 93S IS A COMPACT 
SYSTEM THAT WILL TRACK WEST-SOUTHWEST SLOWLY INTENSIFYING OVER THE 
NEXT 24-48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 
25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 
1002 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL 
CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH. SEE REF B 
(WTXS21 PGTW 080300) FOR FURTHER DETAILS.

      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO 
HIGH.//
