REMARKS: 2 PM (06 GMT) 11 DECEMBER POSITION: 13.6N 117.7E.
^TY Utor has weakened at a greater than climatological rate
over the previous 24 hours due to terrain interaction and
decreased equatorward outflow. TY Utor will continue to
track west-northwestward along the southwestern periphery
of a subtropical ridge (str) located north of Luzon.  From 
48 hrs, TY Utor will begin to track poleward towards a weak-
ness in the str located southeast of Hainan Island. This weak-
ness will be enhanced by a developing midlatitude trough that
is currently over western China...(more info)
