Is it just me or does the JTWC have a tendency to over estimate wind speeds. That doesn't look on par with a cat 4 due to a filled eye and no convection north of the center. Wasn't an issue on meranti before it entered the south China sea. Then I think they were over a little. I see lots of storms given ratings, that, based on satellite appearances do not look that steong. However I'm not familiar with the Dvorak classification or whatever thing they use to determine pressure and intensity.
