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.

Unbelievable. The spaghetti map looks like a rope. And New Orleans continues to party.

Make it a good one, folks.

After looking over several of the websites that talk about and model the catastrophic hits, I think I can sketch out a rough window of where the eye has to pass for the levees to be overtopped (levee or pump failure is another matter.) For a Cat 4 storm, it would need to cross within a rough arc that runs from the MS/LA border, bows out a bit east of Alluvial City, down to Bohemia, west to Larose and Raceland, and north to Reserve(west of the I-10/I-55 split.) If runs east or west enough to stay out of that arc, regardless of angle, in theory the city should be spared the storm surge flood filling the bowl.

While I was watching the Bourbon Street cam the street band was playing "Yellow Submarine"...that might be prophetic.

They've had to evacuate too many times for them to be sensible, although I have heard that the highways really are full of people heading out. I have a friend there waiting...she has to have her son drive her and he's waiting until tomorrow to see what the storm will do.

If it were me, I'd go. This one reminds me too much of the track of Betsy for my comfort level.

Someone earlier in the day posted this. It's an interesting read.

XTRP...that's the best track for US...not good for Mexico, though...

XTRP isn't a model, it's a straight extrapolation of the motion for the last few hours.

It has precisely zero chance of being correct.

Model bias has been west this season... though, if they only shift slightly east, NO is more under the gun. Still waiting for the turn.

And the band plays on in Jackson Square, the buggy rides are still operating, the bars open, and the tourists out. It could be the makings of a very horrific tragedy.

Looks like the mayor would go ahead & shut everything down & call for a mandatory evacuation.

Kind of like watching a train wreck about to happen.

On the TWC's satellite image, there's a well defined eye forming.

Well OFCI is the official track...the others are various computer models.

It's rare to see them that tightly clustered. The models vary in quality and reliability so if they were scattered you'd have to know about the quality of each, but in this case, you really don't.

Roughly 30 miles outside the levees (not city center) on the east and south, a bit less on the west.

Just heard the mayor on WWL 870 am...no mandatory evacuation, He is "encouraging all to leave and will be a little more forceful in the am". "Superdome will open at 8am Sunday for special needs people. All those who can't get out, with no medical needs, no transportation, etc. will be picked up by bus around noon Sunday."

No studies have ever been done to show if the Superdome can withstand a major hurricane. No study has been done to see if generators in the dome will work in the event of a major hurricane.
