Out of all the places in Louisiana what would be the last place you would want to be if 12" inches rain fell in a day?

24 inches fell on May 8-9
1995, in New Orleans. I was there. The water simply had no place to go, so it just got deeper…nothing like what was seen in Texas.

ETA: 1995 not 94

Hopefully he would be of the turd variety that sinks.

BogalUSA

First-
Simply because it would mean that you were in BogalUSA.

Second-
Even with some of 3241 done, you are still a ways away from human civilization

Yup. Lake Charles got 16”-18” in around six hours in May 2021. Six inches fell in an hour. Homes flooded and kids were stuck at school for hours, and I think there was one fatality. But nothing like the danger an event like that in the Hill country can cause.

SELA the water rises slowly with the rain.

Other places the rain will collect in streams and create flash floods along the rivers.

Someone posted yesterday what the river looked like when it got to a bridge. You could see the debris leading the flood and the water turn into a rapids after it got to the bridge.

In SELA, the only way you see that is with a storm surge.


Now on the north shore, some of those rivers can rise pretty quickly if you get rain in Southern Mississippi.

The Hill Country is in a unique area with all the creeks and the Guadalupe River there’s not a place like that in Louisiana because most places have levee systems in place to prevent that. The only way an event like what happened there happens in Louisiana it would take a levee breach.

What these storms did in Texas and Tenn/nc won’t happen like that in La
We don’t have that kind of buildup and runoff

Now backwater flooding is another story in La
