REMARKS:
080300Z POSITION NEAR 25.4S 166.2E.
08APR22. TROPICAL CYCLONE 23P (FILI), LOCATED APPROXIMATELY 187
NM SOUTH OF NOUMEA, NEW CALEDONIA, HAS TRACKED SOUTHEASTWARD AT 08
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY (MSI) DEPICTS A FULLY EXPOSED LOW LEVEL CIRCULATION CENTER 
(LLCC) WITH NO SIGNIFICANT CONVECTIVE ACTIVITY WITHIN 100NM. THE 
PERSISTENT WESTERLY SHEAR AND SMOTHERING EFFECTS OF DRY AIR 
ENCROACHING FROM THE WEST HAVE FINALLY KILLED THE SYSTEM. A 071836Z 
SMAP PASS, AS WELL AS A PARTIAL 072154Z ASCAT-B PASS INDICATED A 
SIGNIFICANTLY WEAKENED WIND FIELD, WITH MAXIMUM WINDS OF 35 KNOTS OR 
LESS ACROSS THE MAJORITY OF THE CIRCULATION. THE SYSTEM WILL 
CONTINUE SLIDING SOUTHEAST THROUGH THE FORECAST PERIOD ALONG THE 
SOUTHWEST SIDE OF THE SUBTROPICAL RIDGE (STR) TO THE NORTHEAST. AS 
THE SYSTEM CONTINUES TO WEAKEN BELOW WARNING CRITERIA, IT WILL 
SIMULTANEOUSLY TRANSITION TO A SUBTROPICAL LOW PRESSURE SYSTEM 
WITHIN THE NEXT 12 HOURS. BEYOND THE FORECAST PERIOD, THE SYSTEM 
WILL SLIDE EAST THEN TURN SOUTHWARD AND THERE REMAINS A LOW 
PROBABILITY OF SOME INTENSIFICATION, BACK TO A GALE-FORCE 
SUBTROPICAL STORM IN THE NEXT 72 HOURS. THIS IS THE FINAL WARNING ON 
THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM 
WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM 
SIGNIFICANT WAVE HEIGHT AT 080000Z
IS 18 FEET.//
