Doc Jon Posted August 30, 2021 Share Posted August 30, 2021 when they say "emergency" doesn't that mean there IS, definitely, already a flash flood going on? 1 1 Link to comment Share on other sites More sharing options...
Santa Claus Posted August 30, 2021 Share Posted August 30, 2021 it's just crazy how many of the big storms over the last decade or so 1) have RI'd right up to landfall and 2) have basically stopped moving shortly after landfall 6 Link to comment Share on other sites More sharing options...

hazwoper Posted August 30, 2021 Share Posted August 30, 2021 From Entergy re. The outage: A company spokesperson said the storm had caused a "load imbalance to the company’s transmission and generation" and that Entergy is "making every effort to identify and rectify." 1 Link to comment Share on other sites More sharing options...

jojo762 Posted August 30, 2021 Share Posted August 30, 2021 3 minutes ago, Doc Jon said: sorry, just wondering if a levee broke. No a levee did not fail... But there is insane rainfall rates across much of the FFE area, with plenty of rain already having fell... In addition Laplace has been getting hammered by surge (see earlier videos posted). Not sure if someone posted it or not, but also saw a video on twitter of flooding in the Lakeview community in NOLA. Link to comment Share on other sites More sharing options...
Syrmax Posted August 30, 2021 Share Posted August 30, 2021 6 minutes ago, hazwoper said: It’s a “catastrophic” transmission issue so I’d say perhaps major damage to main substation and/or massive downing of high tension transmission lines. In a case like this there are probably so many distribution lines down and short circuits that might as well turn the thing off. If the Transmission system goes down that just makes restoration a whole lot longer. Link to comment Share on other sites More sharing options...

It might be similar to why there’s been more numerous heat domes in the past decade as well. my meteorology degree came from a box of Lucky Charms i bought in 2013 but i'd like to venture a guess, weaker jet streams, and a more zonal flow regime. to wit: https://www.wunderground.com/maps/wind/jet-stream and if you look at the national forecast map there's no features to help pick this up, like a passing trough, and i guess that big high over Georgia is also helping hold this back https://www.weather.gov/forecastmaps it's fun trying to figure these things out but i know like 1% of what the board mets do...

MN Transplant Posted August 30, 2021 Share Posted August 30, 2021 Sounds like flooding is bad in the eastern neighborhoods of Laplace. People posting on FB/Twitter for rescues. I checked some of the addresses and they are all in the same area just south of 10. 1 Link to comment Share on other sites More sharing options...

Grep1 Posted August 30, 2021 Share Posted August 30, 2021 How states, counties, townships etc along the coast, allow surface transmission lines is beyond me. Makes absolutely no sense. Let’s put a tree in the ground and attach 480 to it. Hopefully since we call it a pole it will survive 150 mph winds… insanity 1 Link to comment Share on other sites More sharing options...
