1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED 
NEAR 3.0N 144.1E IS NOW LOCATED NEAR 4.4N 144.5E, APPROXIMATELY 540 
NM SOUTH OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 
PARTIAL 110315Z GMI 91GHZ MICROWAVE IMAGE REVEAL DISORGANIZED 
BANDING WRAPPING INTO A WEAK LOW LEVEL CIRCULATION (LLC) WITH 
CYCLING CONVECTION IN THE NORTHERN AND SOUTHERN SEMI-CIRCLES. A 
PARTIAL 110014Z ASCAT-C PASS DEPICTS AN ELONGATED LLC STRETCHING 
FROM THE WEST-SOUTHWEST TO THE EAST-NORTHEAST ALONG WITH A STRONG 
(20-25 KTS) WESTERLY WIND BURST TO THE SOUTH OF THE LLC. INVEST 94W 
IS IN A FAVORABLE ENVIRONMENT FOR TROPICAL DEVELOPMENT WITH ROBUST 
WESTWARD OUTFLOW ALOFT, LOW (5-10 KTS) VERTICAL WIND SHEAR, AND WARM 
(29-30C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GENERAL 
AGREEMENT THAT THE CIRCULATION IN ASSOCIATION WITH INVEST 94W WILL 
CONSOLIDATE AS IT TRACKS TO THE NORTHWEST OVER THE NEXT 24-36 HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 18 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 LOW.
      (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:
      (1) AT 11APR21 0000Z, TROPICAL CYCLONE 28P (TWENTYEIGHT) WAS 
LOCATED NEAR 24.6S 167.9E, APPROXIMATELY 180 NM SOUTH-SOUTHEAST OF 
NOUMEA, NEW CALEDONIA, AND HAD TRACKED SOUTH-SOUTHEASTWARD AT 14 
KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE 
ESTIMATED AT 40 KNOTS GUSTING TO 50 KNOTS. SEE REF A (WTPS31 PGTW 
110300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
