REMARKS:
190900Z POSITION NEAR 21.8N 108.1E.
TROPICAL DEPRESSION (TD) 24W (SARIKA), LOCATED APPROXIMATELY 130 NM
EAST-NORTHEAST OF HANOI, VIETNAM, HAS TRACKED NORTH-NORTHWESTWARD
AT 07 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY INDICATES THAT THE SYSTEM MADE LANDFALL AT 19/05Z
ALONG THE BORDER OF VIETNAM AND CHINA, AND HAS CONTINUED TO WEAKEN
RAPIDLY AS IT TRACKS INLAND. SURFACE OBSERVATIONS FROM MONG CAI,
VIETNAM (48838), APPROXIMATELY 15NM SOUTH-SOUTHWEST OF THE CURRENT
CENTER, REVEALS NORTHWEST WINDS OF ONLY 10 KNOTS WITH SLP NEAR
996.5MB. RECENT ASCAT DATA INDICATES MAINLY 30-KNOT WINDS, WHICH
CORRELATES TO THE CURRENT INTENSITY OF 30 KNOTS. TD 24W IS EXPECTED
TO CONTINUE TO TRACK SLOWLY NORTHWESTWARD TO NORTHWARD BUT IS
FORECAST TO STALL AFTER TAU 12 WHILE DISSIPATING. THERE IS A SLIGHT
POSSIBILITY THAT THE REMNANTS MAY DRIFT BACK OVER WATER AFTER TAU 48
AS INDICATED IN SOME OF THE DYNAMIC MODELS. 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.

Sanya still recording upto 80mph gusts.http://www.ogimet.com/cgi-bin/gsynres?l ... 0&ndays=30

I could not find any pressure observations lower than 970 mb near the landfall location. Looks like Sarika made landfall as a minimal typhoon, and it probably intensified just very slightly in the South China Sea.

[NotoSans]

Lowest pressure recorded in the Philippines was 957.4 hPa in Baler. Sarika passed about 10 km to the north of the weather station, so the central pressure was probably between 945 and 950 hPa at landfall, which would support a minimal category 3 in the western pacific using the normal wind-pressure relationship. The actual intensity may be a bit higher though given that Sarika is a compact storm when it made landfall over Luzon.
