REMARKS:
230900Z POSITION NEAR 30.6S 108.6E.
23JAN25. TROPICAL CYCLONE 10S (SEAN), LOCATED APPROXIMATELY 565 NM
SOUTH-SOUTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTH-SOUTHEASTWARD
AT 10 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS THE FULLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) HAS
BECOME EVEN MORE ELONGATED AND IRREGULARLY-SHAPED AS THE MAIN CONVECTION
IS SHEARED 100+ NM SOUTHEASTWARD. THE INITIAL POSITION IS PLACED WITH 
HIGH CONFIDENCE BASED ON THE EXPOSED LLCC. THE INITIAL INTENSITY OF 
35KTS IS GUARDEDLY HELD SLIGHTLY HIGHER THAN AGENCY AND AUTOMATED DVORAK 
ESTIMATES WITH MEDIUM CONFIDENCE. ANALYSIS INDICATES A HIGHLY 
UNFAVORABLE ENVIRONMENT WITH HIGH (40+ KTS) VWS, COLD (LESS THAN 25C) 
SST, AND COLD DRY AIR ENTRAINMENT. TC SEAN IS EXPECTED TO ACCELERATE 
SOUTHEASTWARD AND DISSIPATE BY TAU 12. 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. MINIMUM CENTRAL PRESSURE AT 
230600Z IS 998MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 230600Z IS 12 
FEET.//
