REMARKS:
040900Z3 POSITION NEAR 18.4N3 137.0E1.
TYPHOON (TY) 34W (SOULIK), LOCATED APPROXIMATELY 419 NM SOUTHWEST OF
IWO JIMA, HAS TRACKED EAST-NORTHEASTWARD AT 03 KNOTS DURING THE PAST 
6 HOURS. THE WARNING POSITION IS BASED ON 040530Z2 VISIBLE AND 
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON 
SATELLITE CURRENT INTENSITY ESTIMATES OF 90 KNOTS. ANIMATED 
SATELLITE IMAGERY DEPICTS CONTINUED WEAKENING OVER THE PAST 6 HOURS.
A SURFACE RIDGE CONTINUES TO BUILD INTO THE WESTERN PACIFIC FROM THE 
ASIAN CONTINENT, NORTH OF THE SYSTEM. CONVECTION ASSOCIATED WITH THE 
SYSTEM CONTINUES TO ELONGATE TO THE EAST. UW-CIMSS ANALYSIS 
INDICATES MODERATE TO STRONG VERTICAL WIND SHEAR OVER THE SYSTEM, 
WITH INCREASING VERTICAL WIND SHEAR TO THE NORTH OF THE SYSTEM. TY 
34W IS CURRENTLY TRACKING NORTHEASTWARD WITHIN A WEAKNESS IN THE 
MID-LEVEL SUBTROPICAL RIDGE. A SURFACE RIDGE HAS BUILT IN NORTH OF 
THE SYSTEM AND WILL SERVE TO SLOW THE FORWARD ADVANCE OF THE SYSTEM 
THROUGH THE PERIOD. THE SYSTEM IS FORECAST TO TRACK TO THE NORTHEAST 
SLOWLY THROUGH THE NEXT 36 HOURS, THEN BEGIN TURNING BACK TO THE 
WEST. INCREASING VERTICAL WIND SHEAR AND COLD AIR INTRUSION WILL 
DISSIPATE THE SYSTEM RAPIDLY OVER THE NEXT 48 HOURS. MAXIMUM 
SIGNIFICANT WAVE HEIGHT AT 040600Z0 IS 16 FEET. REFER TO WWPW30 RJTX 
FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS AT 041500Z0 
(DTG 041351Z4), 042100Z7 (DTG 041951Z0), 050300Z8 (DTG 050151Z2) AND 
050900Z4 (DTG 050751Z8).//
