1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 11APR26 0000Z, TYPHOON 04W (SINLAKU) WAS LOCATED NEAR
8.5N 151.5E, APPROXIMATELY 502 NM SOUTHEAST OF NAVSTA GUAM, AND HAD
TRACKED NORTH-NORTHEASTWARD AT 04 KNOTS OVER THE PAST SIX HOURS.
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 75 KNOTS GUSTING TO
90 KNOTS. SEE REF A (WTPN31 PGTW 110300) 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:
      (1) AT 11APR26 0000Z, TROPICAL CYCLONE 30P (MAILA) WAS LOCATED
NEAR 7.8S 154.6E, APPROXIMATELY 534 NM SOUTH OF KAPINGAMARANGI, AND
HAD TRACKED NORTHEASTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. MAXIMUM
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45
KNOTS. SEE REF B (WTPS31 PGTW 110300) FOR THE FINAL WARNING ON THIS
SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   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 31.3S 177.0E, APPROXIMATELY 382 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 42 TO 48 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.//
