Katrina's storm surge

[f5]

is there any official word on how high Katrina's storm surge was?

[Audrey2Katrina]

It varies widely from place to place; but the worst hit areas seem to have received surge from 20-28 ft. But there is one report of something around a 30-34 ft. near Pass Christian. Unbelievable surge no matter what the final word is.

I think Bay Saint Louis had 28 feet

Yes, A2K - unbelievable is a good definition... My sister, who lives right next door, just had her home surveyed this week and found that her finished floor is at 19.5 feet above sea level. We both had ~two feet in our respective houses here in central Biloxi - about 1 block south of Biloxi Bay on Lafayette Street.

So, it looks like 21.5 feet in our neighborhood...

Okay, I got the surge impact right from the NOAA info:

It's spread out, as I'd stated, and yes, Ixolib, the data indeed shows a 22.5 right there on Biloxi Bay.

What's truly FRIGHTENING is that 34.9 right around Pass Christian across from Waveland. Can you IMAGINE nearly a 35 foot storm surge? This has got to be one for the record books.

if the 35 feet is confirmed, it is likely the highest in the world at least since the Bay of Bengal surge into Bengledesh in 1991

I REMEMBER that storm. I think it was a Cat 5 Cyclone that utterly devastated that poor area. Something like MILLIONS were left homeless. If confirmed it may be the world's record--and I concede it's an if-- it was confined to a much smaller area (thank God), while that one in Bangladesh was massive and hit a much larger area--at least that's what I seem to recall. Tragic! Any data on just how high that one was?

1991 Bay of Bengal storm surge was 20ft and winds at landfall 155 mph.

the world record is the 43 ft surge in the bathurst cyclone in 1899 another contender is 46 ft with a super typhoon that hit the Marshall islands back in June of 1905

good research.....

[f5]

those kind of numbers are scary those surge values look like Tsunami wave heights can you imagine a 40+ ft storm surge leveling Tampa,NO or even NYC

[Jim Cantore]

Does anyone have a SLOSH model graphic of the surge?

[Pearl River]

This is interesting, from the HRD site. The Bathurst Bay Hurricane, also known as Tropical Cyclone Mahina, struck Bathurst Bay, Australia in 1899. According to (Whittingham 1958) it produced a 13 m (about 42 ft) surge, but other contemporary accounts place the surge at 14.6 m (almost 48 ft). Fish and dolphins were reported found ontop of 15 m cliffs.

i wonder what how strong this storm was to produce that kind of surge

Good Lord! That's almost inconceivable.... and may that record stand for a loooong long time!

I couldnt picture that, thats insane, no thats beyond logic

[Audrey2Katrina]

I wonder what the winds were in that thing? Had to be one monster!

not ppssible for the Marhsall Islands to get a 45 ft surge. That value likely was the wave heights. Waters are far too deep to allow even a 12 ft surge there... but the water depths allow for redicuously high waves

thats probably why that value was rejected by the world meterological community beacuse the water there is to deep

you'd need a 200+mph hurricane to do that in the GOM
