Re: About the sonde at 6:24pm AST Tuesday that had momentary surface winds of 193 mph

There are a lot of instances of sondes that are tossed out of the eyewall in the many sondes I was looking at. It's interesting that in the small core of Maria, one actually stayed in. I guess it was not interesting enough to mention in the NHC discussion. I think it's measured over a fraction of a second, so not even a gust, which might be 3 seconds? I don't know.

The NHC's gusts for Maria are 185 knots (213mph), so 193mph isn't surprising even if it were as long as a gust. They might not have wanted to highlight a lower value. There are higher winds, just hard to get a sonde into them. They seem to launch more sondes now than in the past, so it's more likely they'll happen to measure the high winds. Sondes might be made better now too, I don't know. Maybe they are more likely to survive. I don't know how they survive with a little parachute in that kind of wind. I guess the parachute doesn't last.
