Catastrophic Hurricane Ida Produced Wind Gusts over 170 mph, Over 1 Million Without Power in Louisiana...

Category 4 Hurricane Ida is the 2nd strongest hurricane on record to hit Louisiana.  Extreme storm surge, torrential rain and winds produced widespread damage and flooding. 

The Weather Channel reported: 

Hurricane Ida's catastrophic crawl across Louisiana inundated miles of roadways and neighborhoods, ripped apart buildings and trapped hundreds of residents who can't call 911 because service has been knocked out, and cannot be rescued because conditions are still too treacherous to reach them. At least one levee overtopped in lower Jefferson Parish, sending more than 7.5 feet of floodwaters surging into Jean Lafitte, Barataria and Lafitte. Residents there had to flee into their attics to escape the rising water. "Total devastation. It's catastrophic. Our town levees have been overtopped. I have never seen so much water in my life. It's turned into a total rescue mission. People's lives are at stake now," Jean Lafitte Mayor Tim Kerner told WGNO.  More than 1 million customers in Louisiana alone were without power, including all of New Orleans, where catastrophic damage occurred to the city's transformers.

Some of the reports received by the National Weather Service in New Orleans included:
