Re: Ophelia

The "D" item in the vortex message is the estimate of surface wind speed by the onboard meteorologist. That is not the same thing as the maximum flight-level wind, which is noted at the bottom of the message. Human-estimated wind speed, even by a professional, is subject to quite a bit of error, so they usually don't seem to use that information very often.
