RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED NEAR 
9.9N 120.0E IS NOW LOCATED NEAR 9.9N 118.2E, APPROXIMATELY 32 NM WEST-
NORTHWEST OF PUERTO PRINCESA, PHILIPPINES. ANIMATED MSI AND AN 89GHZ 
AMSU-B MICROWAVE IMAGE DEPICT SPARSE, FLARING CONVECTION WRAPPING AROUND 
A BROAD AND DISORGANIZED LLC. ADDITIONALLY, A 050153Z PARTIAL ASCAT 
METOP-B PASS CONFIRMS A BROAD CIRCULATION WITH 15-20KT WINDS NEAR THE 
CENTER AND A SWATH OF 20-25KT WINDS WELL TO THE EAST OF THE CENTER, 
LIKELY ENHANCED BY FUNNELING OF LOW-LEVEL FLOW THROUGH THE PHILIPPINE 
ISLANDS. 93W'S ENVIRONMENT HAS BECOME INCREASINGLY FAVORABLE, 
CHARACTERIZED BY MODERATE UPPER-LEVEL DIVERGENCE, WARM SSTS (29-30C) AND 
LOW (5-10KTS) VWS. A SURFACE OBSERVATION FROM PUERTO PRINCESA REPORTS AN 
MSLP OF 1005 MB. GLOBAL MODELS ARE IN AGREEMENT THAT 93W WILL TRACK 
GENERALLY WEST-NORTHWESTWARD OVER THE NEXT 24-72 HOURS. ALTHOUGH THE 
ENVIRONMENT IS FAVORABLE OVERALL, THE WEAK LOW-LEVEL STRUCTURE AND 
INTERACTION WITH LAND WILL LIKELY CONTINUE TO HINDER DEVELOPMENT IN THE 
NEAR-TERM. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS REMAINS MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
