Hurricane Katrina Live Thread, Part III
NHC-NOAA ^ | 27 August 2005 | NHC-NOAA

Posted on 08/26/2005 10:25:04 PM PDT by NautiNurse

Hurricane Katrina continues to strengthen in the Gulf of Mexico. Currently, the forecast models are converging upon New Orleans. However, all interests in the northern Gulf of Mexico should follow the path of this storm, and be prepared for a major hurricane landfall. Throughout Friday, the official track forecasts moved west, as Hurricane Katrina delayed making the anticipated northwest turn.

The following links are self-updating.

Thanks for posting those helpful links. There's a parallel discussion thread about potential damage to New Orleans on the Weather Underground site at this link:

http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=76&tstamp=200508&allcomments=1

By the way, anyone evacuating from New Orleans probably should skip Alexandria/Pineville as a potential destination. The hotels fill up instantly here and you'll probably be redirected to a shelter.

Prayers to everyone affected by this storm!

Watching the RADAR myself. I think the turn to the west will commence soon. I have this bizarre theory about "friction" in the bands over Cuba and Florida pulling the storm SW. If I am correct, the bands to the south are clearing those mountains and I expect her to turn. But I did not even stay in a Holiday Inn Express last night.

possibly...

but she is already south of her forecasted position...

The further south = the more west she will end up I believe.....

I am still not getting a good vibe here....

You and me both. I am all but pleading with a friend near N.O. to get ready to move. But she will not face 21 hours of traffic again.

Last three frames of RADAR appear to show the turn to west. If so, GDFL appears to remain closest model to actual track over time.

I was wondering if she would make a very abrupt turn and head back across Florida but now do you believe it far enough west? The northern panhandle of Florida could still get whacked.

I think it is going to be a bit west of the last forecast, over or just west of New Orleans. Unless it turns as it is hitting south Louisiana. But I am no expert.

This time last year Frances hadn't yet made landfall, and we still had 9 named storms afterward - including Ivan and Jeanne.

If we have 9 more named storms we will get through Vince. I'm still waiting for the year when they run out of names.

Trivia question: Anyone know how they name storms after they run out of names??

Howdy.

I've had Crawford on the mind and have only been watching Katrina with less than half a mind. By the time I get back Sunday it could be interesting.

I'm Crawford bound!

Here are the remaining names:

Lee, Maria, Nate, Ophelia, Philippe, Rita, Stan, Tammy, Vince, Wilma

I am not sure what they do, probably begin with the letter 'A' again.(?)

Retired Names - Often the same names are used over and over, year after year, but when there is a particularly bad storm that has had a severe impact on the population they retire the name and it is never used again. There will never again be another Hurricane Andrew! Other storms that have had their names retired are:

1960 Donna (1 , 2)

1972 Agnes (1 , 2)

1979 David

1989 Hugo (2)

1992 Andrew (2)

1 - In the top 37 deadliest storms ever

2 - In the top 31 costliest storms ever
