Sarika's circulation has gotten so broad that it actually somewhat resembles a monsoon depression.

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.

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.
