1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED 
NEAR 24.1N 151.3E IS NOW LOCATED NEAR 24.7N 149.8E, APPROXIMATELY 
461 NM EAST OF IWO-TO. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
(MSI) SHOWS A MORE CONSOLIDATED AREA OF CONVECTION WRAPPING INTO A 
MID-LEVEL ROTATION. HOWEVER, THIS SYSTEM IS VOID OF A LOW LEVEL 
CIRCULATION CENTER AND HAS A WEAK BUT TIGHT TROUGHING ASSOCIATED 
WITH A WAVE PROPAGATING NORTHWESTWARD. THIS TIGHT TROUGH IS EVIDENT 
ON THE 272330Z PARTIAL ASCAT-C PASS. ANALYSIS REVEALS A MARGINALLY 
FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH MODERATE EQUATORWARD 
DIVERGENCE ALOFT, LOW TO MODERATE (10-20KT) VERTICAL WIND SHEAR, AND 
WARM (30-31C) SEA SURFACE TEMPERATURES OFFSET BY A TUTT CELL TO THE 
WEST-NORTHWEST. GLOBAL MODELS PREDICT A MODEST INTENSIFICATION AS IT 
TRACKS NORTH-NORTHWESTWARD OVER THE NEXT 24 HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL 
PRESSURE IS ESTIMATED TO BE NEAR 1000 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 280400) 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.
