Good call not issuing a hurricane watch/warning. Maybe some thunderstorm will give recon a 70kt FL wind by tomorrow morning, but I don't see any part of the panhandle getting a 1 minute sustained 64 knot wind tomorrow. A gust in a downdraft? Sure. But not a 1-minute wind. Hurricane watches/warnings need to verify or they lose their impact when issued.

Not questioning you, or being a smart butt...but a 70 or 75 mph gust for less than 20 seconds will bring down trees and do roof damage. So the sustained 1 minute average does not apply, I think. Just putting in by penny worths 8-)

That dry air is a big reason they wouldn't though. That and the cry wolf effect. However I'm almost positive there are arguments going on about doing it or not right now at the NHC.

You're right but the requirement to verify a hurricane is a sustained 1 minute wind of 74 mph. It's not like the one city block that would experience a 75 mph gust will do anything different to their houses if a hurricane warning is issued at 11 pm vs not issued. But issuing a hurricane warning for a million people (wild guess on the FL Panhandle population density) will further the problem of "it's only a cat 1" even though those people likely didn't see any gusts over 50 mph.

Knowing what we know, even a cat 3, normally most will not experience those winds. May just be a small pocket. It may differ sometimes, but in general most wont.

djones65 wrote:It's interesting to note that in the marine advisory they state there are NO 50 kt winds in the NW quadrant... Yet the most recent recon penetration measured surface winds of 50 knots 24 nm NNW of the center. Given it still has 18 hours over water, I find that dubious that these winds will diminish. I am not trying to be hyper-critical, just that I would prefer they err on side of caution and just go with the objective measurements. As of now 50 knot winds appear to exist 24 miles in the northwest quadrant. So why won't they exist later?


I can't speak for NHC but do consider this. A storm moving toward the northwest technically would have it's strongest winds around it's front forward motion "quadrant". Part of that affect is caused by accentuating the speed of the storms' max winds by the additional speed of a storms forward motion. That could very well cause a northwest moving storm to have its strongest winds toward the direction (and of course the storm's "right-front quadrant"). The moment however that such a storm might suddenly begin a sharp turn to the north, "it's right front quadrant" (now toward the north and east) will typically experience the worst weather. Now suddenly, it would be the storms northwest and especially its southwest quadrants where a net decrease effect in the storms max winds might be felt, in part as a result of the storms forward motion.

I knew they would likely find higher winds in that convection.. hurricane force at flight level. Winds should be upped to 70 mph
