In terms of wind, probably. I would hold my breath on flooding though. IIRC, the levee failures took some time to unfold with Katrina. Seemed like the city was going to be basically ok and then...all hell broke loose. 5 1 Link to comment Share on other sites More sharing options...

It goes on for a very long time east of the storm. Really a much longer duration event than you get near the center or west of the center. New Orleans might not improve much until after midnight.

It was basically fine until the levee failures. If the levee didn’t fail in Katrina…Katrina wouldn’t be quite the legend that it is today. 3 Link to comment Share on other sites More sharing options...

sojitodd Posted August 30, 2021 Share Posted August 30, 2021 This storm was not expected to still be anywhere near 120mph sustained winds while 25 miles west of NO, right? Wasn't it supposed to be down to 85 or something like that per the NHC forecasts? I ran some errands and came back and I am surprised it held up this well. And that video from Port Fourchon is incredible. Link to comment Share on other sites More sharing options...

Yeah a majority of the people that are still in danger from wind and the eyewall are poor and impoverished people who were pushed out of the main areas of NO due to Hurricane Katrina. 4 Link to comment Share on other sites More sharing options...

Syrmax Posted August 30, 2021 Share Posted August 30, 2021 5 minutes ago, MattPetrulli said: That is not good. No idea what their backup power requirements are to keep the city drained but my understanding is they need some amount of continuous pumping capability even in normal comditions. If the backup generation fails the pumps don't work. Same thing that bit Fukushima when the tsunami breeched their floodwalls and took out their backup ac power. 4 Link to comment Share on other sites More sharing options...

jac_not_in_dc Posted August 30, 2021 Share Posted August 30, 2021 It is a lesson that seems to need to be learned every time that you don't say that somewhere "dodged a bullet" until the storm is gone and the sun has come up. And even then, you remember that there will be places you don't hear from immediately and those end up being the worst hit. 14 Link to comment Share on other sites More sharing options...

All they stated was that they lost their power supply off the transmission system. I'm guessing that they have substations fed from the High Voltage 115 kv or higher Transmission system. Distribution system at lower voltages probably lost also if the HV and EHV are tripped. It did imply they have a backup source working. How many generators and how much of their pump system that can be supplied...and for how long...no idea. Link to comment Share on other sites More sharing options...

Let’s hope the hospital has ample fuel and working generators. Many folks there rely on oxygen generators working to live. Link to comment Share on other sites More sharing options...
Doc Jon Posted August 30, 2021 Share Posted August 30, 2021 regarding those generators, this IS a government project we're talking about, I'm sure they don't work because somebody put 'em in the basement and it's now flooded! 4 1 2 Link to comment Share on other sites More sharing options...

They assuredly have a test program. The interesting thing is what their fuel supply status is. This is a real concern for nuclear plants...and facilities like this. In these cases, you will be relying 100% on on-site storage as transport of fuel will likely be interuppted for an extended period. Unless they have gas turbine gens connected to the natural gas pipeline system (which is subject to its own failure modes in events like this). We are about to find out how prepared they really were. Would hate to see the levees hold but have a different failure mode cause flooding problems. 1 Link to comment Share on other sites More sharing options...
