1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   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) AN AREA OF CONVECTION (INVEST 92P) HAS PERSISTED NEAR 15.9S 
166.6E, APPROXIMATELY 148 NM NORTHWEST OF PORT VILA, VANUATU. THE 
SYSTEM IS CURRENTLY CLASSIFIED AS A SUBTROPICAL CYCLONE, GENERALLY 
CHARACTERIZED AS HAVING BOTH TROPICAL AND MIDLATITUDE CYCLONE 
FEATURES. THE SYSTEM IS LOCATED UNDER THE LEADING EDGE OF A DEEP 
UPPER-LEVEL SUBTROPICAL TROUGH WITH 30-40 KNOT NORTHWESTERLIES OVER 
THE CENTER. THE DEEP MOISTURE PROFILE IS HIGHLY ASYMMETRIC, WITH 
EXTENSIVE DRY AIR OVER THE WESTERN QUADRANT. ANIMATED MULTISPECTRAL 
SATELLITE IMAGERY DEPICTS A BROAD, ASYMMETRIC SUBTROPICAL SYSTEM WITH 
MULTIPLE MESOVORTICES EMBEDDED IN THE ELONGATED CENTER. A 090306Z ATMS 
88.2 GHZ MICROWAVE IMAGE REVEALS AN ASYMMETRIC CONVECTIVE STRUCTURE, 
WITH A LINEAR BAND OF DEEP CONVECTION ASSOCIATED WITH THE STRONG LOW-
LEVEL CONVERGENT FLOW ALONG THE NORTHERN AND EASTERN PERIPHERIES OF 
THE SYSTEM. A 082243Z ASCAT-C IMAGE SHOWS A BROAD CIRCULATION WITH 
WEAK CORE WINDS (5-10 KNOTS), CONVERGENT GALE-FORCE STRENGTH 
NORTHWESTERLY TO NORTHERLY WINDS NEAR VANUATU, AND SIGNIFICANTLY 
WEAKER WINDS DISPLACED TO THE SOUTHWEST. GLOBAL MODELS INDICATE A 
SOUTHEASTWARD TRACK OVER THE NEXT TWO DAYS WITH NEAR GALE-FORCE WINDS 
PERSISTING OVER THE NORTHEASTERN SEMICIRCLE. 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 30 TO 35 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 
IS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.//
