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 
5.7N 153.4E IS NOW LOCATED NEAR 9.2N 152.4E, APPROXIMATELY 520 NM 
EAST-SOUTHEAST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
DEPICTS DEEP CONVECTION OBSCURING THE BROAD LOW-LEVEL CIRCULATION 
CENTER (LLCC) WITH CONVECTIVE BANDING WRAPPING ALONG THE SOUTHERN 
SEMICIRCLE. ENVIRONMENTAL ANALYSIS REVEALS A FAVORABLE ENVIRONMENT FOR 
DEVELOPMENT WITH STRONG EQUATORWARD OUTFLOW, LOW VERTICAL WIND SHEAR 
(10-15 KTS), AND WARM SEA SURFACE TEMPERATURES (28-29 C). GLOBAL 
MODELS AGREE ON 90W SLOWLY TRACKING GENERALLY WESTWARD AS IT 
CONSOLIDATES OVER THE NEXT 24-48 HOURS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 18 TO 23 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 IS UPGRADED TO 
HIGH. SEE REF C (WTPN21 PGTW 081800) 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:
      (1) AT 08APR26 0600Z, TROPICAL CYCLONE 31P (VAIANU) WAS LOCATED 
NEAR 23.4S 177.8E, APPROXIMATELY 1079 NM NORTH OF WELLINGTON, NEW 
ZEALAND, AND HAD TRACKED SOUTH-SOUTHEASTWARD AT 13 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 75 
KNOTS GUSTING TO 90 KNOTS. SEE REF A (WTPS32 PGTW 080900) FOR FURTHER 
DETAILS.
      (2) AT 08APR26 1200Z, TROPICAL CYCLONE 30P (MAILA) WAS LOCATED 
NEAR 8.6S 155.7E, APPROXIMATELY 584 NM SOUTH OF KAPINGAMARANGI, AND 
HAD TRACKED WESTWARD AT 02 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 105 KNOTS GUSTING TO 130 
KNOTS. SEE REF B (WTPS31 PGTW 081500) FOR FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA. 1.B.(1) TO 
HIGH.//
