REMARKS:
160900Z6 POSITION NEAR 19.9N9 112.6E0.
TROPICAL DEPRESSION (TD) 08W, LOCATED APPROXIMATELY 190 NM
SOUTH-SOUTHWEST OF HONG KONG, HAS TRACKED NORTH-NORTHWEST AT 10 
KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 
160530Z5 VISIBLE AND INFRARED SATELLITE IMAGERY, AVAILABLE SYNOPTIC 
DATA, AND EXTRAPOLATION FROM PAST POSITIONS. THE WARNING INTENSITY 
IS BASED ON CURRENT SATELLITE INTENSITY ESTIMATES OF 25 KNOTS AND 
SYNOPTIC REPORTS. ANIMATED SATELLITE IMAGERY DEPICTS A VERY POORLY 
DEFINED SYSTEM POSSIBLY CONSISTING OF MULTIPLE LOW LEVEL CIRCULATION 
CENTERS (LLCC) WITH CONVECTION DEVELOPING IN THE VICINITY OF THESE 
LLCCS AND BEING SHEARED TO THE SOUTHWEST. UW-CIMSS ANALYSIS 
INDICATES WEAK TO MODERATE VERTICAL WIND SHEAR OVER THE SYSTEM. THE 
SUBTROPICAL RIDGE NORTHEAST OF THE SYSTEM WILL ACT AS THE DOMINATE 
STEERING MECHANISM THROUGH THE FORECAST PERIOD. THE SYSTEM IS 
FORECAST TO MOVE INCREASINGLY NORTHWARD INTO A WEAKNESS IN THE 
SUBTROPICAL RIDGE. TD 08W IS FORECAST TO MAINTAIN MINIMAL TD 
STRENGTH DUE TO A PERSISTENT UNFAVORABLE VERTICAL WIND SHEAR 
ENVIRONMENT THROUGH 24 HOURS WITH A POSSIBLE INTENSIFICATION BEFORE 
LANDFALL. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 160600Z3 IS 10 FEET. 
REFER TO WWPW30 RJTX FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT 
WARNINGS AT 161500Z3 (DTG 161351Z7), 162100Z0 (DTG 161951Z3), 
170300Z1 (DTG 170151Z5) AND 170900Z7 (DTG 170751Z1).//
