Harvey - Main Thread

Recommended Posts

Austin about to get drenched again, the center is still drifting NW and a nice band is heading into the city. The airport's already getting it. 

As for "Rt. 290's been dry", radar is already estimating over 4" in that corridor, and it's raining hard there now and especially down toward Rt. 71. There's another 24-36 hours coming. 

Austin itself has 2-3" so far, 1" in the northwest suburbs.

What were the highest confirmed winds recorded at landfall? Sustained 100 with gusts to 113 was the highest I saw. 

Port Aransas gusted to 132 mph (Cat 4 strength) at one point.

At 8:58pm, the station recorded 114G131.

 

Also, there was a VDM with a reliable 113kt surface wind during landfall time. Definitely supports the cat 4 designation.

I'm honestly shocked their weren't higher sustained winds reported with higher gusts. Maybe it just wasn't reaching the surface but I figured it would with how intense that western eyewall was. Reed claimed 140+ gusts in his video

131 is damn impressive. There aren't many reporting stations that were operational during the height of the storm, and none in Rockport.

the structural damage there, including demolished brick buildings and completely collapsed framed buildings suggests winds over 140.

There were quite a few reports of anemometers breaking as the storm approached even before the eyewall. May have had something to do with it.

Certainly possible, although RT can be a little cray cray too.

It might've somewhere right at the water's edge, but perhaps nobody recorded it. There are literally tons of cases where the maximum sustained wind isn't actually observed by any instrument on the ground. As is, 114 is 88% of 130, and I'd wager that the cat 4 designation was appropriate.

Harvey has been downgraded, took over 15 hours after landfall to lose hurricane status. Impressive.

This almost always happens and it drives me crazy. Blame the anemometers. <_< It's also possible some of the more impressive observations haven't been reported yet, I guess.

GFS slowly dissipates inland, cuts down rain totals for Houston metro.

 

CMC takes it back offshore, drowns Houston metro.

 

Interesting to see what the Euro does.

Euro: back out to sea.

Again -- for the second time.

 

Port Aransas recorded 114mph, gusting to 131 at 8:58.

 

Also -- this was at/shortly after landfall:

I think we have enough evidence to support Cat 4 winds at the surface along the coast -- especially taking in consideration where Port Aransas was in relation to the max wind band.

Reed had a sensor strapped to a bridge. It'll be interesting to see what that shows. Not an official 10m ob by any means, but better than no data.

 

Also, I'm sure damage analysis can do a decent job estimating peak winds and wind swath in the next few days (as hinted above).

ECMWF remains persistent in wanting to take Harvey back out over the gulf. Restrengthening by 72 hours and a little stronger than the 00z.

 

and then back in again! lol
