1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 98W) HAS PERSISTED NEAR 9.6N 
143.8E, APPROXIMATELY 225 NM SOUTH-SOUTHWEST OF GUAM. ANIMATED 
ENHANCED INFRARED SATELLITE IMAGERY DEPICTS A BROAD LOW-LEVEL 
CIRCULATION (LLC) WITH FLARING, DISORGANIZED CONVECTION OVER THE 
SOUTH AND EAST QUADRANTS. A 220635Z SSMIS 91GHZ MICROWAVE IMAGE 
REVEALS A WEAKLY-DEFINED LLC. A 221034Z ASCAT-A IMAGE SHOWS A BROAD 
CIRCULATION WITH 05-15 KNOT WINDS SURROUNDING A WEAK CORE. UPPER-
LEVEL ANALYSIS INDICATES A MARGINALLY FAVORABLE ENVIRONMENT WITH 
WEAK EQUATORWARD OUTFLOW AND LOW VERTICAL WIND SHEAR. SEA SURFACE 
TEMPERATURES OF 30C ARE CONDUCIVE FOR FURTHER DEVELOPMENT. GLOBAL 
MODELS INDICATE THIS DISTURBANCE WILL GRADUALLY DEVELOP AS IT TRACKS 
NORTHWESTWARD OVER THE NEXT TWO DAYS WITH MORE SIGNIFICANT 
DEVELOPMENT ANTICIPATED WEST OF GUAM. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS 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.
3. JUSTIFICATION FOR REISSUE: ADDED LOW AREA IN PARAGRAPH 1.B.(1).//
