Re: HURRICANE IRMA LOUNGE

Estimating winds in tropical cyclones -

The forward speed addition is already included in the maximum wind speed. You do not add to that. However, if you are on the left side of a tropical cyclone's forward motion, it is reasonable to subtract the forward speed to get the max possible for that side.

Once tropical cyclones are over land, their maximum sustained winds over water tend to show up as gusts, rather than 1-min averages ("sustained").
