Re: recon interpretation

While some aren't keen on my rough formula. I simply take the Max Flight Level Wind and change the knots to mph.
Last Vortex has 89kts MFLWind. Roughly 89mph at surface.
Formula for 700mb would be:
89 x 1.15=102.35mph MFLW x 0.91= 93.14mph at surface.
The 89kts to 89mph is the quick formula. And gives a rough estimate of the lower end of the maximum surface winds.
Here's the Official NHC page on Eyewall Wind Profiles.
