REMARKS:
091500Z POSITION NEAR 27.9N 120.2E. 09AUG26. TYPHOON 12W (DOLPHIN), 
LOCATED APPROXIMATELY 175 NM NORTH-NORTHWEST OF TAIPEI, TAIWAN, HAS 
TRACKED WESTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. ANIMATED 
ENHANCED INFRARED (EIR) SATELLITE IMAGERY AS WELL AS ANIMATED RADAR 
DATA INDICATE THAT TYPHOON 12W MADE LANDFALL ALONG THE EASTERN COAST 
OF CHINA NORTHEAST OF WENZHOU AROUND 0915Z. THE SYSTEM THEREUPON 
TRACKED SOUTHWESTWARD, MOST LIKELY PASSING IN CLOSE PROXIMITY TO 
WENZHOU ITSELF AND CONTINUING TO A POSITION WEST OF RUIAN BY 1200Z. 
SURFACE OBSERVATIONS FROM RUIAN SHOW WINDS FROM THE SOUTH-SOUTHWEST, 
SUPPORTING THE INITIAL POSITION TO THE WEST OF THE STATION AT 1200Z, 
WITH HIGH CONFIDENCE. NOW OVER LAND, TY 12W WILL DRIFT SOUTHWEST FOR A 
BIT LONGER BEFORE QUICKLY TURNING NORTHWESTWARD ALONG THE SOUTHWESTERN 
FLANK OF A LARGE SUBTROPICAL RIDGE (STR) CENTERED TO THE NORTHEAST. 
THE SYSTEM WILL RAPIDLY WEAKEN OVER THE RUGGED TERRAIN, DISSIPATING 
OVER EAST-CENTRAL CHINA WITHIN THE NEXT 48 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. 
MINIMUM CENTRAL PRESSURE AT 091200Z IS 958 MB. REFER TO TROPICAL STORM 
13W (PEILOU) WARNINGS (WTPN32 PGTW) FOR SIX-HOURLY UPDATES. REFER TO 
TROPICAL STORM 14W (CHAN-HOM) WARNINGS (WTPN33 PGTW) FOR SIX-HOURLY 
UPDATES.//
