Although most of those structures weren't very well built, that is solid Cat.3 damage in that video probably the worst wind damage I have seen since Charley.


I agree on the 3 looking damage in that piece. But I think there was way more smashed up and mangled damage in Rita, Ike and then on the Mississippi Gulf Coast with Katrina where anything not concrete piled up miles inland. I've actually never seen an area as wiped clean as that. Frank P who lives there will tell you. Slabs. Unlike Andrew where the destruction was complete but was due in large part to the wind and everything looked like matchsticks, this just swept through and took blocks away. Anything left standing had no doors, windows or contents as they got scoured out. I'm not trying to hype Katrina at all. But if you haven't looked at some of the before after pictures from BSL, Long Beach, Pass Christian, Gulfport or Biloxi, you owe yourself some research. That's not to downplay Charley either. It was a beast and smashed a ton of stuff along the way. It was a small storm thankfully though that has often been cited as a reason it got so strong. I feel like if Harvey was a larger storm and/or was not all that far up or down the coastline, damage to coastal cities and beach towns would have been much more widespread.

Wasn't most of that damaged done by the surge? They are saying alot of the damage in Rockport was from the winds.

THIS IS NOT CONJECTURE, IT IS A REQUEST FROM THESE AGENCIES!! AND YES IT IS SOMEWHAT PERSONAL AS MY CHILDREN AND GRANDS JUST WENT THROUGH THIS!! Still don't know if my daughters house is ok. Know son and family are fine. Also know Daughter and family are ok, just don't know about the house. Am definitely blessed, but do not want to go through this again!!


Any damage reports?


Local Houston Channel 2 (NBC affiliate) has a reporter on the ground in the Lone Oak subdivision in Cypress talking to a homeowner and showing damage. Tornado went between his house and next door house. Damaged trees, gutters, roof, hole in front of garage above door, blew out back window in his truck, etc. Doesn't look like major damage, but plenty enough damage to deal with. Guys were there taking down a tree that went down in front of his front door.

It's 86 at Hobby. There is some very warm and unstable air getting wrapped into the circulation off the Gulf. Probably enhancing the tornado threat in the Houston area.

Yes, I would agree with that.. to make my point, my house was completely leveled with only a clean slab left... I eventually found my second floor up the street on the next block... Most of all my shingles were still on.. and I think the ones that were torn off was not from the wind but from roof impacting the low level Oak tree limbs as it had to pin pong off about a dozen Oaks to make it to its final resting spot.. Additionally, most of my neighbors who did not have their houses completely leveled by the 25 foot storm surge amazing had very little, if any wind damage with practically all their shingles still on their roof... And I am talking about houses only 1 block off the beach...

Harvey is at the same latitude as Galveston bay now and made a wobble ENE or maybe even due east. By morning it may be close enough to the coast so that the circulation is again pumping some heavier rain bands up into Houston off the gulf. Can't model this with such weak steering winds.

Has anyone talked about or videoed the potential damage to the hundreds of wind turbines in that area? Last time we drove to CC from Houston, we passed by miles and miles of turbines. We questioned at that time what damage a hurricane would inflict on them. We know they hadn't been tested by a cat 4 hurricane til now.


I read an article the other day, http://fortune.com/2017/08/26/hurricane-harvey-threatens-texas-wind-farms/ They shut them down and let them pinwheel

TV news just reported possible tornado touchdown. Wharton County Office of Emergency Management says it's just north of East Bernard. House and trailer could be damaged. Tornado warning from Rosenberg to Katy. That feeder band in that area is strong.

Mesoscale Discussion 1579
NWS Storm Prediction Center Norman OK
0600 PM CDT Sat Aug 26 2017

Areas affected...Upper TX Coast...Far Southwest LA

Concerning...Tornado Watch 468...

Valid 262300Z - 270100Z

The severe weather threat for Tornado Watch 468 continues.

SUMMARY...The threat for tornadoes continues across all of WW 468. A
locally enhanced area of tornado potential exists from League City
northwest to Brenham.

DISCUSSION...Recent radar imagery shows a feeder band arcing from
the Fayette/Washington county border through western Fort Bend and
Brazoria county, moving gradually eastward at about 15-20 kt. Cells
within this band are moving north-northeastward at around 30 kt.
Lightning has been observed in the cells in Fort Bend and Brazoria
counties.

Modest diurnal heating was realized just downstream of the line with
LVJ and HOU reporting temperatures of 87 and 86 deg F, respectively,
at 22Z. Resultant steepening of the low-level lapse rates could
contribute to better low-level stretching and a locally enhanced
tornado potential. Additionally, surface streamline analysis shows
an area of convergence roughly oriented from HOU northwestward to
just south of 11R. This convergence zone could also contribute to
locally enhanced tornado potential.

Wonder if this is the beginning of perhaps a possible loop, or starting his movement back towards the GOM... something is happening though, he is definitely not stationary any more..

Looks like a slight ENE movement on satellite

Yeah. That's what we were saying and agreeing on.

Well if he does make it back to the Gulf, and that's a big IF... would not surprise me at all, if the can get far enough off the coast, to regenerate to at least a Cat 1, his circulation is very still impressive for being inland for almost a full day... if, if, if...

This may persist for some time.
A large pool of 4500 CAPE air is sitting offshore from Houston and Harvy's circulation is pushing it inland.
This is mixing with an area of moderate helicity inland that is spawning the tornadoes.
Helicity is created from boundary-layer turbulence due to frictional effects of land.

Stay safe everyone in this area.

Harvey looking better now than he did just a couple of hours ago on the Sat images... strong feeder band developing to the south of the center...

The utter flattening you saw in Rita and Katrina was generally surge+wave damage. Water is incredibly powerful. Almost nothing built for land use can stand up to a big ocean wave.
