1. Looks like

It's moving east, ever so slightly...

[geomon666]

2. It just keeps getting faster and stronger

Damn

[steve2470]

3. ON TWC, they are comparing this storm to Camille

And Camille was a mofo. Actually, the barometric pressure of this one is the lowest on record, if I recall correctly.

[KyndCulture]

4. Yes the Navy weather site has recorded the lowest pressure

ever in the Gulf of Mexico with this storm.

[geomon666]

6. The 1935 storm which obliterated Key West had lower pressure.

But not by much.

[KyndCulture]

8. Gulf pressure... that was probably an atlantic pressure...

but yeah, I think you are right.

[Mnemosyne]

10. Thanks for all the info steve! There was one at 888mb

but can't recall which one. It was in another thread.

I have been in one hurricane. Opal. When it reached Montgomery the winds were sustained at 115mph. It was frightening, I can't imagine the horror this one will bring.

Our environment is rebelling.

Has this cat. ever strengthened? Is it possible? The 90degree temp. of the Gulf concerns me deeply.

May God help those that can't leave.

[steve2470]

14. wow 888 mb is damn low. They just reported 902 mb for Katrina

Did you know 6000 people died in Galveston in 1900 from a hurricane ?

[Mnemosyne]

16. I've read that, horrifying death toll..

It might have been the Galveston cane that had the 888mb. I'll look for the thread.

I am praying for those left. There doesn't seem to be much else to do now. Is there? It feels so helpless watching such tragedy unfold and be unable to do a damn thing!! We'll have some rain here, NW PA, and flooding most likely. I just wish that was all NO and all were facing.

May God help them, or whatever energy anyone prays to.

[geomon666]

17. It was Hurricane Gilbert

In addition, Hurricane Gilbert of 1988 was a Category Five hurricane at peak intensity and is the strongest Atlantic tropical cyclone on record with a minimum pressure of 888 mb.

[Mnemosyne]

19. Thank you geo. n/t

[Reverend_Smitty]

5. Even Hurricane Andrew was only a Cat 4

and we saw what that storm did to south Florida. My thoughts and prayers really go out to those stranded in its path

[geomon666]

7. Andrew was a CAT 5 n/t

[Reverend_Smitty]

9. oh was it

for some reason I thought it was only a cat 4...but still they are in for a lot of trouble when it hits, especially with less guardsmen at home and a gutted FEMA budget

[KayLaw]

11. They upgraded Andrew

Posthumously.

[geomon666]

12. At the time

It was estimated as a CAT 4 but at the time the NHC lost all of it's equipment because of the storm. New evidence discovered has since elevated that storm to CAT 5.

[DoYouEverWonder]

13. Andrew destroyed the device

that measures wind at the National Hurricane Center in Coral Gables. No one knows how high the winds really got in that storm but I think the device broke at about 220 MPH.

[Hissyspit]

15. kick

[merbex]

18. I am really afraid that the city of New Orleans as we know it had its

last normal day a few days ago

I heard some official say outloud that serious consideration should be given to rebuilding NO somewhere else

It hasn't hit yet and people that understand this storm and the geography of the area are essentially saying NO is a goner

Godspeed to all those fleeing and our prayers are with those remaining
