REMARKS:
032100Z POSITION NEAR 23.2N 120.9E.
03OCT24. TROPICAL DEPRESSION 20W (KRATHON), LOCATED APPROXIMATELY 130 
NM SOUTH-SOUTHWEST OF TAIPEI, TAIWAN, HAS TRACKED NORTH-NORTHEASTWARD 
AT 04 KNOTS OVER THE PAST SIX HOURS. COMPOSITE RADAR LOOP CLEARLY 
SHOWS THE SYSTEM HAS TRACKED DEEP INTO THE SOUTHEASTERN MOUNTAIN 
RANGES OF TAIWAN WITH PEAKS OVER 5000 FT. THE RUGGED TERRAIN HAS 
EFFECTIVELY ERODED MOST OF THE DEEP CONVECTON ASSOCIATED WITH TD 2OW 
AND DECAPITATED IT FROM THE REMNANT LOW LEVEL CIRCULATION CENTER. THE 
INITIAL POSITION IS PLACED WITH MEDIUM CONFIDENCE BASED ON THE RADAR 
LOOP. THE INITIAL INTENSITY IS ALSO ASSESSED WITH MEDIUM CONFIDENCE 
BASED ON NEARBY SURFACE WIND AND MEAN SEA LEVEL OBSERVATIONS. TD 
KRATHON IS EXPECTED TO TRACK FURTHER NORTHWARD OVER THE MOUNTAIN 
RANGES AND DISSIPATE BY TAU 12, LIKELY SOONER. 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 031800Z IS 1002 MB.//
