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:
      (1) AT 24MAR26 0000Z, TROPICAL CYCLONE 28P (TWENTYEIGHT) WAS 
LOCATED NEAR 23.6S 163.8E, APPROXIMATELY 156 NM SOUTHWEST OF NOUMEA, 
NEW CALEDONIA, AND HAD TRACKED SOUTHWARD AT 22 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS 
GUSTING TO 55 KNOTS. SEE REF A (WTPS31 PGTW 240300) FOR THE FINAL 
WARNING ON THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) AN AREA OF CONVECTION (SS 28P) HAS PERSISTED NEAR 23.6S 
163.8E, APPROXIMATELY 156 NM SOUTHWEST OF NOUMEA, NEW CALEDONIA. THE 
SYSTEM IS CURRENTLY CLASSIFIED AS A SUBTROPICAL CYCLONE, GENERALLY 
CHARACTERIZED AS HAVING BOTH TROPICAL AND MIDLATITUDE CYCLONE 
FEATURES. ANIMATED ENHANCED MULTISPECTRAL SATELLITE IMAGERY DEPICTS 
DISLOCATED BUT FLARING CONVECTION LOCATED JUST POLEWARD AND EASTWARD 
OF THE LOW-LEVEL CIRCULATION CENTER (LLCC). THE SYSTEM HAS CONTINUED 
TO BE SHEARED TO THE SOUTH-SOUTHEAST, WITH THE LLCC BECOMING ONLY 
PARTIALLY OBSCURED ALONG THE PRIMARY CONVECTIVE STRUCTURES 
NORTHWESTERN QUADRANT, TYPICAL OF A SUBTROPICAL CYCLONE. A PARTIAL 
232232Z METOP-C ASCAT IMAGE HAS REVEALED A HIGHLY ASYMMETRIC LOW-LEVEL 
WIND FIELD, WITH 35 KTS IDENTIFIED WITHIN THE EASTERN SEMICIRCLE. 
ENVIRONMENTAL ANALYSIS REVEALS UNFAVORABLE CONDITIONS FOR TROPICAL 
TRANSITION, DEFINED BY A DEEP LAYER OF MID-LEVEL DRY AIR BEING 
ENTRAINED THROUGHOUT THE SYSTEMS CORE, STRONG NORTH-NORTHWESTERLIES 
ALOFT, HIGH VERTICAL WIND SHEAR (VWS) OF 40-50 KTS, AND COOL SEA 
SURFACE TEMPERATURES OF 25-26 C. GLOBAL MODELS ARE IN AGREEMENT THAT 
SUBTROPICAL CYCLONE 28P WILL TRACK SOUTHWARD WITH AN INCREASINGLY 
BROAD AND ASYMMETRIC WIND FIELD.  MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 40 TO 45 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 994 MB. FOR HAZARDS AND WARNINGS, REFERENCE THE FLEET 
WEATHER CENTER SAN DIEGO HIGH WINDS AND SEAS PRODUCT OR REFER TO LOCAL 
WMO DESIGNATED FORECAST AUTHORITY. THE POTENTIAL FOR THE DEVELOPMENT 
OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.
3. JUSTIFICATION FOR REISSUE: UPDATED AREA IN PARA 2.A.(1) WITH 28P 
FINAL WARNING INFORMATION AND ADDED AREA IN 2.C.(1) AS A LOW.//
