REMARKS:
242100Z POSITION NEAR 21.8N 135.0E.
24APR21. SUBTROPICAL STORM (SS) 02W (SURIGAE), LOCATED APPROXIMATELY 
438 NM WEST-SOUTHWEST OF IWO TO, JAPAN, HAS TRACKED EAST-
SOUTHEASTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. THE SYSTEM 
REMAINS ASSESSED AS A SUBTROPICAL STORM BUT IS EXPECTED TO RAPIDLY 
TRANSITION TO AN EXTRA-TROPICAL LOW WITHIN THE NEXT 12 TO 18 HOURS. 
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY CONTINUES TO DEPICT A 
HIGHLY ASYMMETRIC, FRONTAL STRUCTURE WITH EXTENSIVE DRY AIR PUNCHING 
INTO THE WESTERN AND SOUTHERN PERIPHERIES. THE SYSTEM IS LOCATED 
UNDER A MAJOR UPPER-LEVEL TROUGH WITH STRONG VERTICAL WIND SHEAR AND 
IS EMBEDDED WITHIN A STRONG BAROCLINIC ZONE AS EVIDENCED BY 
EXPANSIVE COLD-AIR STRATOCUMULUS IN SATELLITE IMAGERY. THE INITIAL 
INTENSITY REMAINS ASSESSED AT 40 KNOTS BASED ON RECENT ASCAT DATA AS 
WELL AS A 240911Z SENTINEL-1B SAR PASS, WHICH INDICATES MAXIMUM 
WINDS OF 40-48 KNOTS. SS 02W IS FORECAST TO TRACK EASTWARD TO EAST-
NORTHEASTWARD WHILE UNDERGOING EXTRA-TROPICAL TRANSITION (ETT). 
SURIGAE WILL COMPLETE ETT AS A MINOR SHORT-WAVE TROUGH, CURRENTLY 
LOCATED SOUTH OF KYUSHU, DIGS SOUTHEASTWARD OVER THE NEXT 12 TO 18 
HOURS PROVIDING UPPER-LEVEL SUPPORT. THE SYSTEM MAY INTENSIFY 
SLIGHTLY AS AN EXTRA-TROPICAL LOW TOWARD THE END OF THE FORECAST 
PERIOD AND WILL REMAIN A LARGE, GALE-FORCE LOW AS IT TRANSITS SOUTH 
OF JAPAN. NUMERICAL MODEL GUIDANCE REMAINS IN TIGHT AGREEMENT 
LENDING HIGH CONFIDENCE TO THE JTWC FORECAST TRACK. 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 241800Z IS 22 
FEET.//
