Re: Dean Reaches Category 4 Strength

Hate to say it Random Chaos, but that recon report was the one where they got the 145mph winds.
138kts at flight level, times 90% = 124.2kts at surface, which is 142.83mph.

Line D is an unofficial estimate of the winds based upon what they see from the aircraft, as I understand it, it's not the official wind speed reported, which is based upon an extrapolation of 90% of flight level (at the level they are currently flying).

When in doubt, take the word of the National Hurricane Center.
