This thing has Category 2 pressures as a tropical storm. That’s absurd.

Looks like JTWC went with 60 kts / 970 hPa for the 0z Best Track point. (CMA has 70 / 970, and JMA 55 / 975.)

When was the last time that a tropical storm had this absurdly low of a pressure?

The title of this thread needs to be corrected back to "Severe Tropical Storm", because JMA still hasn't upgraded it (and they probably won't, due to their inexplicable hatred of typhoons that pass through or form in the South China Sea)

Edited the title but JMA is very conservative with the data available from dvorak etc.

All ground data suggest this is a legit typhoon
