PACIFIC OCEANS REISSUED/060000Z-060600ZMAR2023//
RMKS/
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 (REMNANTS 16P) HAS PERSISTED NEAR 29.0S 
171.3W, APPROXIMATELY 515 NM SOUTH-SOUTHEAST OF TONGA. THE SYSTEM IS 
CURRENTLY CLASSIFIED AS A SUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED AS 
HAVING BOTH TROPICAL AND MIDLATITUDE CYCLONE FEATURES. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY (MSI) AND AN EARLIER SSMIS 91GHZ 
MICROWAVE IMAGE DEPICT A FULLY EXPOSED LOW LEVEL CIRCULATION CENTER 
(LLCC) WITH FRAGMENTED CONVECTION IN THE EASTERN PERIPHERY. A 052001Z 
ASCAT METOP-C SCATTEROMETER PARTIAL BULLSEYE REVEALED THE LLCC AS WELL AS 
THE LARGE SWATHS OF 35-40KT WIND FIELDS WRAPPING TOWARDS THE LLCC AND 
SOME POCKETS OF 50 KNOTS TO THE NORTH. ENVIRONMENTAL CONDITIONS PROVE TO 
BE HIGHLY UNFAVORABLE FOR TC REGENERATION WITH THE MAJOR LONG WAVE 
PATTERN MOVING IN OVER THE SYSTEM AND BRINGING WITH IT HIGH (40-60KTS) 
VWS. THE REMNANTS OF TC 16P HAS CROSSED INTO MUCH COOLER (24-25C) WATERS 
AND HAS AN ABUNDANCE OF DRY AIR WRAPPING INTO IT. GLOBAL MODELS AGREE 
THAT REMNANTS 16P WILL CONTINUE TO DWINDLE DOWN AS IT GETS PICKED UP 
WITHIN THE LONG WAVE PATTERN OVER THE COURSE OF THE NEXT FEW DAYS THUS 
COMPLETELY ENDED ITS REIGN AS A POSSIBLE REGENERATING TC. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 47 TO 53 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 985 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: ADDED AREA IN 2.C.(1) AS A LOW.//
