   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92B) PREVIOUSLY LOCATED NEAR 
10.3N 96.7E IS NOW LOCATED NEAR 10.5N 95.2E, APPROXIMATELY 163 NM EAST-
SOUTHEAST OF PORT BLAIR, ANDAMAN ISLANDS. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY (EIR) SHOWS A PERSISTENT, BROAD ELONGATED DISTURBANCE 
IN THE SOUTHEASTERN REGION OF THE ANDAMAN SEA THAT IS EXHIBITING A 
DISORGANIZED LOW LEVEL CIRCULATION (LLC) WITH SOME CONVECTION.  A 
PARTIAL 201238Z SSMIS PASS SHOWS WEAK TURNING AND SOME LOW WINDS AROUND 
15-20 KTS IN THE NORTHEASTERN QUADRANT. UPPER LEVEL ANALYSIS INDICATES 
INVEST 92B IS IN AN AREA WITH MODERATE (10-20 KT) VWS, MODERATE 
DIVERGENCE AND EQUATORWARD OUTFLOW. WARM SEA SURFACE TEMPERATURES AT 27-
28C. OVERALL, THE ENVIRONMENT IS JUST MARGINALLY FAVORABLE. GLOBAL 
MODELS ARE IN GOOD AGREEMENT THAT 92B WILL CONTINUE TO TRACK GENERALLY 
NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 
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 REMAINS LOW.
