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 6.4N 153.0E, APPROXIMATELY 89 NM 
SOUTHEAST OF CHUUK. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICT 
A BROAD AREA OF CYCLONIC TURNING WITH DENSE FLARING CONVECTION OBSCURING 
THE LOW LEVEL CENTER. THE POSITION IS BASED ON THE CENTROID OF THE 
OVERALL CIRCULATION AND PROMINENT MID-LEVEL FLOW. ENVIRONMENTAL ANALYSIS 
INDICATES 90W IS CURRENTLY IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT 
BEING CENTERED IN A LOWER POCKET (10-15 KT) OF VERTICAL WIND SHEAR, WARM 
(29-30 C) SEA SURFACE TEMPERATURES, AND A POINT SOURCE JUST EAST OF THE 
LOW-LEVEL CIRCULATION CENTER (LLCC) ASSISTING WITH MODERATE POLEWARD 
OUTFLOW. GLOBAL MODELS ARE IN GOOD AGREEMENT ON A WESTWARD TRACK WITH 
INTENSIFICATION OVER THE NEXT 24-48 HOURS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1002 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:
      (1) AT 08APR26 0000Z, TROPICAL CYCLONE 31P (VAIANU) WAS LOCATED 
NEAR 22.2S 177.4E, APPROXIMATELY 252 NM SOUTH-SOUTHWEST OF SUVA, FIJI, 
AND HAD TRACKED SOUTH-SOUTHEASTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 80 KNOTS GUSTING TO 
100 KNOTS. SEE REF A (WTPS32 PGTW 080300) FOR FURTHER DETAILS.
      (2) AT 08APR26 0000Z, TROPICAL CYCLONE 30P (MAILA) WAS LOCATED 
NEAR 9.0S 155.9E, APPROXIMATELY 757 NM NORTHEAST OF CAIRNS, AUSTRALIA, 
AND HAD TRACKED NORTHWARD AT 05 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 115 KNOTS GUSTING TO 140 
KNOTS. SEE REF B (WTPS31 PGTW 080300) FOR FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
