1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 11APR26 1800Z, TYPHOON 04W (SINLAKU) WAS LOCATED NEAR 9.3N 
151.5E, APPROXIMATELY 475 NM EAST-SOUTHEAST OF NAVSTA GUAM, AND HAD 
TRACKED NORTH-NORTHEASTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 95 KNOTS GUSTING TO 115 KNOTS. 
SEE REF A (WTPN31 PGTW 112100) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   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:
      (1) THE AREA OF CONVECTION (INVEST 31P) PREVIOUSLY LOCATED NEAR 
28.2S 178.8E IS NOW LOCATED NEAR 34.9S 176.9E, APPROXIMATELY 141 NM 
NORTH-NORTHEAST OF AUCKLAND, NEW ZEALAND. THE SYSTEM IS CURRENTLY 
CLASSIFIED AS A SUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED AS HAVING 
BOTH TROPICAL AND MIDLATITUDE CYCLONE FEATURES. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY (MSI) DEPICTS A VERY WELL-DEFINED LOW-LEVEL 
CIRCULATION CENTER (LLCC) EMBEDDED WITHIN A TIGHT SWIRL OF MID-LEVEL 
CLOUD BANDS, ABSENT OF ANY DEEP CONVECTION. ENVIRONMENTAL ANALYSIS 
REVEALS UNFAVORABLE CONDITIONS FOR DEVELOPMENT CHARACTERIZED BY HIGH 
VERTICAL WIND SHEAR (20-30 KNOTS), MODERATE UPPER LEVEL POLEWARD 
OUTFLOW, AND COLD SEA SURFACE TEMPERATURES (23-24 C). GLOBAL MODELS 
AGREE ON A SOUTHWESTWARD TRACK OVER THE NEXT 24-48 HOURS. FOR HAZARDS 
AND WARNINGS, REFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH WINDS 
AND SEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST AUTHORITY. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 33 TO 38 KNOTS. MINIMUM 
SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 989 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
REMAINS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.
