REMARKS:
230900Z POSITION NEAR 32.4N 126.3E.
23AUG21. TROPICAL DEPRESSION 16W (OMAIS), LOCATED APPROXIMATELY
135 NM SOUTH-SOUTHWEST OF JEJU ISLAND, SOUTH KOREA, HAS TRACKED 
NORTHWARD AT 24 KNOTS OVER THE PAST SIX HOURS. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY (MSI) SHOWS THE FULLY-EXPOSED LOW 
LEVEL CIRCULATION HAS BEGUN TO ELONGATE AND UNRAVEL AS IT 
ACCELERATED DEEPER INTO HIGHER RELATIVE VERTICAL WIND SHEAR (VWS) IN 
THE EAST CHINA SEA. THE SYSTEM HAS BEEN STRIPPED OF ANY CONVECTION. 
THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE 
DEFINED LLC IN THE MSI LOOP. THE INITIAL INTENSITY IS ASSIGNED WITH 
HIGH CONFIDENCE BASED ON THE CLUSTERED PGTW, RJTD, AND KNES DVORAK 
FIXES OF T1.5/25KTS. ANALYSIS INDICATES AN UNFAVORABLE ENVIRONMENT 
WITH HIGH (40KTS+) VWS AND COOLING SSTS (27C AND DECREASING)SLIGHTLY 
OFFSET BY MEDIUM EQUATORWARD OUTFLOW. TD 16W WILL CONTINUE TO 
ACCELERATE NORTHEASTWARD ALONG THE POLEWARD SIDE OF THE SUBTROPICAL 
RIDGE TO THE EAST, CROSS SOUTH KOREA, AND EXIT INTO THE SEA OF JAPAN 
AFTER TAU 12. THE HARSH ENVIRONMENT PLUS LAND INTERACTION WILL 
DISSIPATE THE SYSTEM BY TAU 12. 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 230600Z IS 10 FEET.//
