Incredible how fast it put itself together being so close to shore, wouldn’t be surprised if Cempaka’s already a typhoon.

I didn’t expect it to blow up this fast, but it looks like this is another win for the HWRF. Watch the JTWC/JMA go with a 60 kt STS.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.
