Nervous in New Orleans.
#1
Big chance of a hurricane forming that could tip some flooding records over there it seems. 

https://earther.gizmodo.com/new-orleans-faces-catastrophic-flooding-ahead-of-possib-1836245310?IR=T

Forum pal's US mate lives there and they're asking for "thoughts and prayers' already!  ... tongue in cheek hopefully, but genuinely worried.  
Quote:Quote: (from email)  Bigger problem, Mr. Naut, is that the Mississippi River is at 16 feet in New Orleans, one foot below flood stage. A Cat 1 land falling to the west of NOLA will push the river level to 20 feet or more. The lowest river levees here are 20 feet. Record river level ever in NOLA was 21.7 feet during the great flood in 1927. If the river over tops the levees, or one of them breaches, and we get 10"" of rain, it could make the flooding after Katrina look like a walk in the park. To top it all off, we had 7" of rain this morning in 3 hours. There was flooding all over the city.


Say a prayer for us, guys!


How's the flood levels in Ky now Stanky?  everything back to normal yet?

I've been keeping an eye on this story - New Orleans looks to be in a race with Jakarta for the first major city to have to be abandoned through rising sea levels.

NO might be getting a jump if this developing hurricane has any say.

What has rising sea level got to do with heavy rains flooding rivers and hurricanes making life difficult?

And where are they rising? They haven't started selling any harbourside mansions in Sydney yet and they're about a meter clear of high tide.

Rising sea levels make it far more difficult for low land to get rid of it's overburden of rainwater Di. And, the higher sea level is, the higher the storm surge will be as well, and that's where a lot of the flooding fun comes from too. The World Ocean isn't exactly a big bucket of water. It can get screwed in one place like Jakarta without necessarily getting screwed in Sydney at the same time.

Gee, lemme think....

If a river flows into the sea, does the level of the sea make a difference to the outflow?

The side note of higher sea levels amplifying storm surge is hardly worth mentioning in that context.

Everywhere.

Well, at 2 mm a year - which is Sydney's rate on increase - I'd give them no more than another 50 years before storm surges start washing them away. That's of course, presuming it doesn't start rising faster, which is entirely possible. Quite likely, even, with the recent speeding up of both Greenland and Antarctica's ice sheet melt.

You can't seriously have any doubts about sea level - the numbers are black and white.

Yep. 2mm per year, you just said so.

So I stand edjumakated 2mm sea level rise equals 20 foot river rise. got it.

No. Stop it. At least without putting a smiley face on it.

Methinks you're being deliberately obtuse, but I'll take a chance.

The river is higher because of floods up-river. The sea level rise exacerbates a problem that already existed.
