With the strength of Katrina increasing constantly, I was wondering what the record wind speed of a hurricane is up tuntil now.
What is the current record for wind speed??

I would also like to know this. I know it's already over the threshold for Cat 5.

I'd like to be the first to report that the all time record is 231 mph on Mount Washington in New Hampshire, in what was an average storm.
For hurricanes I'm not sure. The 1938 hurricane that hit New England has a 190 gust at the Blue Hill Observatory in Massachusetts. The winds recorded by airplanes and extrapolated from dropsondes have been higher.

For a Hurricane out at sea Gilberts recording with 888mb was associated with 160kts at 700mb which Katrina exceeded early today.

Can those count as 10m observations?

Mount Washington and Blue Hill were both 10m observations. 10 meters above their respective observation site.

What about the Labor Day hurricane of 1935? I believe the average wind speed was about 200 mph, or was this just an estimate?

Just like with F-scale ratings pre 1980, I'm suspsicious of high-end meteoorlogical obs in the early 1900s. I imagine it was an "estimated max" windspeed, but remember the old 1960s news stories about tornadoes and how they thought max winds in tornadoes may reach 500-600mph?

On another note, what is considered "Landfall" Is it when the entire hurricane is over land or when the eye is over land?
Jeff Snyder

Usually "landfall" occurs when the center of the eye finally crosses the coast. Of course, the most intense conditions are felt near the eyewall.

Right, I was thinking one or the other. Thanks.

Yes, I go along with you here. Of course, no anemometer will measure a 200 mph windspeed.
Perhaps the highest winds with a hurricane are the 190 mph sustained winds measured with supertyphoon Tip (monster storm over the Pacific in 1979; 1,350 miles in diameter, infrared temperature of eye wall -135°F).

I don't know, and I don't know if this was posted, but a 233 kt gust was reported by a dropsonde at 866 mb earlier today. Not confirmed BTW.

I saw that gust report too. Keep in mind reduction to surface probably is equivelant to a 180-190 knots. As a gust. Not really unexpected with 150 knot sustained winds.

There were estimated gusts between 215-220 from Camille. Here is a link with some before and after shots of the damage swath from Camille. There is also a satellite picture of her when she was over the gulf. Pretty scary stuff.
