Advocate has a pretty interesting story today about some researchers who are saying a direct hit from a Cat 4 hurricane could cause widespread flooding even in BR south of the Highland Road bluff. Seems kind of hard to believe, but pretty interesting. If a hurricane can ever flood BR this bad, I imagine points south would be totally decimated.

Perhaps a meteorite in the gulf, but not a hurricane..

WBRP didn't flodd during a 1,000 year storm but a Cat 4 is gonna swamp it?

How many miles inland did Katrina surge in MS? A couple of miles? Maybe 5?


This map seems.... off.

If you get a slow moving low-mid category storm, then yeah, it could. More water in than out = flooding. Storm surge coming north and rivers going south. Ask St. Tammany and St. John Parishes about Hurricane Isaac.

The latest maps show that coastal flooding from a Category 3 hurricane nearing the coastline could push water over much of Baton Rouge that lies between Highland Road and the Mississippi River, depending on the storm's track and conditions at the time.


In what world are these idiots living in? How in God's name can a cat 3 storm surge flood BR? This is the epitome of fear mongering for readership. The Advocate is such a pile of shite.

How many cat 3 and cat 4 hurricanes have we experienced here, and tell me when we've come even close to flooding here in BR?

Would take a Cat 4 sitting over south LA for 5 days or more to make water move that far inland. Storm surge creeps inland and is slowed by vegetation and other bottlenecks. And its not possible for a Cat 4 to maintain strength sitting over land anyway. Somebody thought it would be fun to remind us south-of-I10 folks how low our land sits above sea-level.

I assume that map is saying storm surge in conjunction with rain, i.e. the rain water has nowhere to drain.

It depends on how much wetlands have been eroded and how high sea levels rise.

I've seen these studies before that essentially projected those results after 50 years of continuous unchecked wetland loss and a sea level rise (worst case scenario) of 3 feet.

weakened systems produce more rain that cat 4 or 5... level

It varied greatly for the most part, based on the waterways that allowed the surge to push further and higher in than otherwise. That's key.
