RMKS/
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) AN AREA OF CONVECTION (INVEST 96S) HAS PERSISTED NEAR 7.7S 
80.8E, APPROXIMATELY 496 NM EAST OF DIEGO GARCIA. ENHANCED INFRARED 
SATELLITE IMAGERY DEPICTS A LOW-LEVEL CIRCULATION CENTER (LLCC) PARTIALLY 
OBSCURED BY DEEP CONVECTION OVERHEAD. A 131520Z AMSU-B 89GHZ MICROWAVE 
IMAGE REVEALS FORMATIVE BANDING WRAPPING INTO A DEFINED LLCC. A PARTIAL 
131540Z ASCAT-B PASS REVEALS AN ELONGATED CIRCULATION WITH A SWATH OF 20-
25 KNOT WINDS IN THE SOUTHERN QUADRANT. ENVIRONMENTAL CONDITIONS ARE 
MARGINALLY FAVORABLE WITH MODERATE OUTFLOW ALOFT AND WARM (28-29) SST, 
OFFSET BY LOW TO MODERATE (15-20KT) NORTHEASTERLY VWS. GLOBAL MODELS ARE 
IN GENERAL AGREEMENT THAT INVEST 96S WILL REMAIN QUASI-STATIONARY OVER 
THE NEXT 24-48 HOURS BEFORE MEANDERING SOUTHWESTWARD. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 22 TO 27 KNOTS. MINIMUM SEA LEVEL PRESSURE 
IS ESTIMATED TO BE NEAR 1006 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.//
