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 
15.0N 116.8E IS NOW LOCATED NEAR 14.5N 116.1E, APPROXIMATELY 284 NM 
WEST OF MANILA. THE SYSTEM IS CURRENTLY CLASSIFIED AS A MONSOON 
DEPRESSION, GENERALLY CHARACTERIZED AS A LARGE CYCLONIC CIRCULATION, 
GREATER THAN 600NM DIAMETER, WITH EXTENSIVE GALE-FORCE WINDS OVER THE 
SOUTHEASTERN PERIPHERY AND A WEAK CORE OF LIGHT WINDS. MULTISPECTRAL 
SATELLITE IMAGERY (MSI) DEPICTS CONVECTIVE BANDING WITH A BROAD BUT 
RAPIDLY CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC). THE IMAGERY 
ALSO HIGHLIGHTS UPPER-LEVEL CONVECTION ON THE SOUTHERN SIDE OF THE 
CIRCULATION. ENVIRONMENT ANALYSIS REVEALS FAVORABLE CONDITIONS WITH 
LOW VERTICAL WIND SHEAR, GOOD EQUATORWARD OUTFLOW ALOFT, AND WARM (28-
29 C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE SHOWING SIGNIFICANT 
DEVELOPMENT WITH A NORTHWESTWARD TRACK OVER THE NEXT 24 HOURS. FOR 
HAZARDS AND WARNINGS, REFERENCE THE FLEET WEATHER CENTER SAN DIEGO 
HIGH WINDS AND SEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST 
AUTHORITY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 
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 IS UPGRADED TO HIGH. SEE REF A (WTPN21 PGTW 280330) 
FOR FURTHER DETAILS.
      (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.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO HIGH//
