REMARKS:

061500Z POSITION NEAR 9.6N 150.3E.

TROPICAL DEPRESSION 05W (HAISHEN), LOCATED APPROXIMATELY 149 NM

NORTHWEST OF CHUUK, HAS TRACKED NORTH-NORTHWESTWARD AT 07 KNOTS

OVER THE PAST SIX HOURS. ANIMATED ENHANCED IR IMAGERY REVEALS VERY

LITTLE DEEP CONVECTION ASSOCIATED WITH TD O5W, THE MAJORITY OF IT

SIGNIFICANTLY SHEARED OFF. A 061120Z AMSU-B GIVES MODERATE

CONFIDENCE IN THE INITIAL POSITION OF THE SYSTEM. UPPER-LEVEL

ANALYSIS INDICATES A CONTINUED UNFAVORABLE ENVIRONMENT WITH HIGH (20

TO 30 KNOT) SOUTHWESTERLY VERTICAL WIND SHEAR (VWS). TD 05W IS

CURRENTLY QUASI-STATIONARY UNDER THE STEERING INFLUENCE OF THE

WEAKENING SUBTROPICAL RIDGE TO THE NORTHWEST AND A NEAR EQUATORIAL

RIDGE TO THE SOUTH. EXPECT DISSIPATION OF THE SYSTEM THROUGHOUT THE

ENTIRE FORECAST PERIOD WITH COMPLETE DISSIPATION BY TAU 24 DUE TO

INCREASED VWS. 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. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 061200Z

IS 10 FEET.//
