RMKS/
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 92B) PREVIOUSLY LOCATED NEAR 
17.9N 86.7E IS NOW LOCATED NEAR 18.2N 86.2E, APPROXIMATELY 166 NM EAST 
OF VISAKHAPATNAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS 
A SHALLOW CONSOLIDATING EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH 
CURVED LOW-LEVEL CLOUD BANDING. A PARTIAL 080341Z GPM GMI 89GHZ 
MICROWAVE IMAGE DEPICTS DEEP CONVECTION SHEARED TO THE WESTERN 
SEMICIRCLE OF THE LLCC. ENVIRONMENTAL ANALYSIS REVEALS A MODERATE 
ENVIRONMENT WITH HIGH VERTICAL WIND SHEAR OF 15-20 KNOTS, MODERATELY 
DIFFLUENT EQUATORWARD OUTFLOW AND WARM SEA SURFACE TEMPERATURES OF 29-30 
DEGREES C. THE PRIMARY INHIBITING ENVIRONMENTAL FACTOR IS THE ELEVATED 
VERTICAL WIND SHEAR, HOWEVER A SHARP GRADIENT EXISTS AND THE SHEAR 
ENVIRONMENT IS MORE FAVORABLE AS THE SYSTEM PASSES FARTHER NORTH. GLOBAL 
MODELS INDICATE STEADY DEVELOPMENT OVER THE NEXT 24 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 994 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
REMAINS HIGH.
      (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.//
