REMARKS:
100900Z POSITION NEAR 20.7N 106.3E.
10OCT21. TROPICAL DEPRESSION 22W (LIONROCK), LOCATED APPROXIMATELY 
41 NM EAST-SOUTHEAST OF HANOI, VIETNAM, HAS TRACKED WEST-
NORTHWESTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. A COMPOSITE RADAR 
LOOP FROM CMA AND SURFACE OBSERVATIONS IN VIETNAM INDICATE TD 22W 
HAS MADE LANDFALL NEAR CAT BI INTERNATIONAL AIRPORT. THE INITIAL 
POSITION IS BASED WITH HIGH CONFIDENCE ON A DEFINED LOW LEVEL 
CIRCULATION IN THE RADAR LOOP. THE INITIAL INTENSITY OF 25KTS IS 
EXTRAPOLATED WITH MEDIUM CONFIDENCE FROM NEARBY WIND AND MSLP 
OBSERVATIONS, INCLUDING THOSE FROM CAN BI AIRPORT. TD LIONROCK IS 
EXPECTED TO CONTINUE TRACKING INLAND AND ERODE RAPIDLY AND DISSIPATE 
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. REFER TO TROPICAL STORM 23W (NAMTHEUN) 
WARNINGS (WTPN32 PGTW) FOR SIX-HOURLY UPDATES. REFER TO TROPICAL 
CYCLONE 24W (KOMPASU) WARNINGS (WTPN33 PGTW) FOR SIX-HOURLY 
UPDATES.//
