1. REMARKS: THIS CANCELS REF A (WTPN21 PGTW 281230). THE AREA OF 
CONVECTION (INVEST 90W) PREVIOUS LOCATED NEAR 8.9N 139.9E IS NOW LOCATED 
NEAR 8.8N 139.4E APPROXIMATELY 88 NM EAST-SOUTHEAST OF YAP. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY DEPICTS A PARTLY EXPOSED LOW LEVEL 
CIRCULATION WITH THE UPPER LEVELS BEING SHEARED TO THE SOUTH AND THE 
MAJORITY OF THE CONVECTION ALSO TO THE SOUTH. UPPER LEVEL ANALYSIS 
INDICATES THE SYSTEM HAS DRIFTED INTO AN AREA OF MODERATE (20-25 KNOT) 
VERTICAL WIND SHEAR, WITH CONTINUED POLEWARD OUTFLOW. GLOBAL MODELS NO 
LONGER SHOW DEVELOPMENT OF THE SYSTEM. MAXIMUM SUSTAINED SURFACE WINDS 
ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 1004 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO LOW.//
