A lot of people without power right now, with more to come:

In the peak of summer, no less. Sucks.

Also, big chlorine fire at plant near Lake Charles.

Chlorine was used as a chemical weapon in WW1.

Far too close. Props to NHC for keeping the track consistent while diurnal model fluctuations could have caused more chaos.

T&P to the people of SW Louisiana, and major destruction and devastation in Lake Charles. Som many people still without power and/or damage to their homes.

Watching the tropics while back to the usual summer weather. At least the back fence is shored up.

I saw a lot of comments online about not moving the track westward near Houston when this ECMWF ensemble plot came out. #Laura actually made landfall outside of that ensemble (and that model usually has too much spread). Trust the professionals and don’t just worship one model!

TBF, 3 out of 4 Ensembles had a Texas solution. Props to the NHC, though.

^^ I hope it works!

Our daughter was born yesterday at 10:40am and all back home. Thankful as all get out Laura spared us here in Houston! Prayers to all affected. That first cool front can’t get here fast enough!

Yep, agreed. The NHC did a fantastic job. But I saw plenty of Pro-mets with forecasts of this going into Texas. Here is a snippet of a reply I posted on S2K, replying to one of our own friends about falling for the "Euro Ensemble" trap:

That's easy to say in hindsight, so don't be too hard on yourself. It wasn't just the 'Euro ensembles' and some anecdotal evidence the west trend would continue. There were plenty of solid arguments [at the time] for Laura going more west into Texas:

1) Laura, for most of her entire track, had been tracking on the west side of the guidance.
2) The Euro ensembles that showed the western shift, when analyzed individually, made the most meteorological sense at the time [for example, almost all of the ensembles with a stronger storm - a hurricane - went to Texas - and we all knew Laura would be a hurricane]
3) Verified pressures of the ridge versus the model verification, esp. the GFS, showed the SE ridge was a bit stronger than modeled.
4) The Euro Ensembles weren't alone. The UKMET was west, the PARA GFS had shifted west, and a most of the GFS ensembles were on Texas.

For a short period of time, it appeared that Texas, perhaps Galveston, was becoming a certainty.
