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 98W) PREVIOUSLY LOCATED NEAR 
10.0N 137.7E IS NOW LOCATED NEAR 10.5N 137.5E, APPROXIMATELY 70 NM 
NORTH-NORTHWEST OF YAP. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
DEPICTS A WEAK BROAD LOW-LEVEL CIRCULATION (LLC) ASSOCIATED WITH 
DISORGANIZED CONVECTION IN THE NORTHEASTERN AND SOUTHWESTERN 
PERIPHERIES. A 040038Z PARTIAL ASCAT-B PASS REVEALS A BROAD CIRCULATION 
WITH SHARP TROUGHING TO THE NORTHEAST. THE 042316Z MHS 89GHZ AND
040344Z ATMS 88.2GHZ MICROWAVE IMAGES REVEAL INTENSE CONVECTIVE BURSTS 
ALONG THE TROUGH LINE TO THE NORTHEAST. INVEST 98W IS IN A FAVORABLE 
ENVIRONMENT FOR DEVELOPMENT, CHARACTERIZED BY MODERATE OUTFLOW ALOFT 
AND LOW (5-10KT) VERTICAL WIND SHEAR. SEA SURFACE TEMPERATURES REMAIN 
CONDUCIVE AT A WARM 30C. DETERMINISTIC AND ENSEMBLE MODELS CONTINUE TO 
AGREE THAT INVEST 98W WILL BE SLOW TO DEVELOP AS IT MEANDERS POLEWARD 
OVER THE NEXT 48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED 
AT 10 TO 15 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.
      (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.//
