SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 08W (KUJIRA)
WARNING NR 13//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
   TROPICAL STORM (TS) 08W (KUJIRA), LOCATED APPROXIMATELY 120 NM
EAST-SOUTHEAST OF HANOI, VIETNAM, HAS TRACKED WESTWARD AT 08 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
(MSI) SHOWS THE CENTRAL CONVECTION CONTINUES TO BE DISPLACED
SOUTHWESTWARD OF A  PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER
AS THE SYSTEM DRIFTS ACROSS THE GULF OF TONKIN TOWARDS THE VIETNAM
COAST. THE INITIAL INTENSITY OF 35 KNOTS IS BASED ON THE DVORAK
ESTIMATE FROM PGTW. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM
REMAINS IN A POOR ENVIRONMENT WITH HIGH (25-30 KNOT) VERTICAL WIND
SHEAR AND LIMITED EQUATORWARD OUTFLOW. TS KUJIRA IS TRACKING UNDER
THE STEERING INFLUENCE OF AN EXTENSION OF THE MID-LEVEL SUB-TROPICAL
RIDGE (STR) TO THE NORTHEAST.
3. FORECAST REASONING.
   A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
   B. TS KUJIRA IS EXPECTED TO TRACK MORE NORTHWESTWARD UNDER THE
STEERING INFLUENCE OF THE STR THROUGHOUT THE FORECAST PERIOD. IT
IS EXPECTED TO MAKE A FINAL LANDFALL OVER THE NORTHERN COAST OF
VIETNAM BY TAU 12. AFTERWARDS, THE SYSTEM WILL RAPIDLY WEAKEN AS IT
MOVES INLAND, DISSIPATING BY TAU 24. AVAILABLE MODEL GUIDANCE REMAINS
IN GOOD AGREEMENT LEADING TO HIGH CONFIDENCE IN THE JTWC FORECAST
TRACK.//
