      (1) THE AREA OF CONVECTION (INVEST 92A) PREVIOUSLY LOCATED 
NEAR 17.9N 74.1E IS NOW LOCATED NEAR 17.8N 70.7E, APPROXIMATELY 140 
NM SOUTHWEST OF MUMBAI, INDIA. ANIMATED ENHANCED INFRARED (EIR) 
SATELLITE IMAGERY AND A 161631Z METOP-B 89GHZ SATELLITE IMAGE DEPICT 
A PARTIALLY-EXPOSED LOW LEVEL CIRCULATION (LLC) WITH FLARING 
CONVECTION SHEARED OVER THE WESTERN SEMICIRCLE. UPPER LEVEL ANALYSIS 
INDICATES UNFAVORABLE (15-20 KNOT) VERTICAL WIND SHEAR (VWS) PARTLY 
OFFSET BY GOOD DIVERGENCE ALOFT. GLOBAL MODELS ARE IN GOOD AGREEMENT 
THAT INVEST 92A WILL INTENSIFY SLIGHTLY AS IT TRACKS WESTWARD 
TOWARDS THE ARABIAN PENINSULA. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 1001 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
