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 97W) PREVIOUSLY LOCATED
NEAR 8.3N 178.8E IS NOW LOCATED NEAR 8.5N 173.2E, APPROXIMATELY 322
NM EAST OF KWAJALEIN ATOLL. ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY AND A 150420Z SSMIS 91GHZ MICROWAVE IMAGE DEPICT A
LOW LEVEL CIRCULATION WITH SHALLOW BANDING WRAPPING AROUND THE BROAD
CENTER; HOWEVER, THERE ARE FRAGMENTED DEEP CONVECTIVE BANDS IN THE
EASTERN SEMICIRCLE. A 142223Z METOP-B ASCAT IMAGE REVEALS 15-20KT
EASTERLY WINDS IN THE NORTHERN SEMICIRCLE AND 5-10KT WINDS
ELSEWHERE. THE ENVIRONMENT IS MOSTLY FAVORABLE FOR FURTHER
DEVELOPMENT WITH WARM (29-30 CELSIUS) SEA SURFACE TEMPERATURES, LOW
(<15KTS) VERTICAL WIND SHEAR, AND GOOD POLEWARD OUTFLOW. THE
LIMITING FACTORS ARE THE SIGNIFICANT DRY AIR IN THE MID-LEVELS AS
EVIDENCED IN RECENT MAJURO AND KWAJELEIN SOUNDINGS, AS WELL AS THE
LACK OF STRONG WESTERLIES. CURRENTLY NO GLOBAL MODELS INDICATE
SIGNIFICANT DEVELOPMENT OF THIS SYSTEM AS IT TRACKS WEST-
NORTHWESTWARD. 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 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.//
