REMARKS:
110300Z POSITION NEAR 22.2N 107.4E.
TROPICAL STORM (TS) 31W (HAIYAN), LOCATED APPROXIMATELY 87 NM
NORTHEAST OF HANOI, VIETNAM, HAS TRACKED NORTHWARD AT 13 KNOTS OVER 
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY 
INDICATES THAT TS 31W IS RAPIDLY WEAKENING AS IT TRACKS FURTHER 
INLAND WITH THE BULK OF THE CONVECTION DISPLACED OVER THE NORTHERN 
SEMI-CIRCLE DUE TO INCREASING SOUTHWESTERLY VERTICAL WIND 
SHEAR (20 TO 25 KNOTS). THERE IS FAIR CONFIDENCE IN THE INITIAL 
POSITION. THE INITIAL INTENSITY IS ASSESSED AT 60 KNOTS BASED ON THE 
RJTD DVORAK FINAL-T AND CURRENT INTENSITY ESTIMATES (55/65 KNOTS). 
TS 31W IS TRACKING ALONG THE WESTERN PERIPHERY OF THE SUBTROPICAL 
RIDGE, WHICH IS QUICKLY ERODING DUE TO STRENGTHENING MIDLATITUDE 
WESTERLY FLOW ACROSS SOUTHERN CHINA. TS 31W IS FORECAST TO TURN 
EASTWARD AS IT BECOMES EMBEDDED WITHIN THE WESTERLY FLOW AND IS 
FORECAST TO DISSIPATE OVER LAND BY TAU 36. BASED ON THE TIGHT 
AGREEMENT OF DYNAMIC MODELS, THERE IS HIGH CONFIDENCE IN 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.//
