Worst Case Scenario for NO [Re: Random Chaos]
      #50650 - Sat Aug 27 2005 09:23 AM

Worst Case Scenario

"The worst case is a hurricane moving in from due south of the city," said Suhayda, who has developed a computer simulation of the flooding from such a storm. On that track, winds on the outer edges of a huge storm system would be pushing water in Breton Sound and west of the Chandeleur Islands into the St. Bernard marshes and then Lake Pontchartrain for two days before landfall.

One thing that makes me think the westward adjustments should not continue is based on persistence forecasting. Granted, this is not a good way to make accurate forecasts, but can be generally useful. For example, back in 1996 ( I am sure Phil remembers this) any shortwave that moved towards the east coast generated a snow storm, even innocuous looking weaklings. It wanted to snow, and it wanted to snow over my house, and it did to the tune of 66" for the year.
Since last year, the NE GOM has a bullseye on it. Even without tropical systems, rainfall anomalies are in a well-defined pattern. It is illustrated by the drought monitor map at the link below:
http://www.cpc.ncep.noaa.gov/
Recent climatology suggests the biggest impact will be east of the Mississippi. Eventually, this analog will no longer work, but I go with them until they do not. You can pretty much see by that map the mean position of the offshore high. That doesn't mean I think NO is out of the woods, just that I don't expect forecasts to keep shifting west.

P.S. to anyone who lives in that area: Try to get Jim Cantore and Stephanie Abrams banned from your towns. Hurricanes only hit where they sit.




Reminds me of the jokes from last year about Florida. But, it makes good sense.

      #50655 - Sat Aug 27 2005 09:31 AM

Good morning from Atlanta.....

In watching all our local mets and following the many different shifts in computer models, I have to feel 3 things........

1) I still think that the entire Gulf Coast from Galveston to the Big Bend is still in play until Katrina starts to make the forecast Northerly turn. With the history of this storm, it seems that Kat does not follow conventional logic or what we are used to with tropical systems. This storm is going to be studied and studied on what caused it to act the way it is. With that being said...If your local EOC tells you to evacuate, then by all means EVACUATE! That's their job to protect and save lives and a little inconvience now could save many lives.

2) I have to call onto the carpet the local TV mets here in Atlanta stating on the 11pm news that we are out of the woods here in Atlanta for any flooding rain or severe weather. Just because Kat did not produce any severe weather in the right front quadrant when she made her inital landfall, DOES NOT mean that it wont happen with the second landfall. The NWS office in Peachtree City is still calling for 4-7 inches of rain and the only thing that has changed from their forecast is the timing of that occurance.

3) I have a nagging question that someone could answer for me.....a) Would it be entirely possible that Katrina could just stay on a westerly course and go right into Mexico?

Be vigilant everyone and Thanks....

Jeff in Atlanta

You know it's a bad day.....when you wake up and see Jim Cantore and Geraldo Rivera broadcasting from your backyard....literally!

Disclaimer: I'm not a MET so this is just my speculation

Is it possible? Yes, ANYTHING is possible with Katrina.

It's not going to happen, though. It might take a week, but a second U.S. landfall seems certain - somewhere between Texas and Key West.

ETA: If there's a MET online, I've got a question for speculation. Could Katrina pull an Opal? I mean, head northwest toward New Orleans, but then get swept up and thrown northeast (not NNE, but NE) and hit the Panhandle? Several people are saying a Panhandle landfall isn't out of the question, but what I'm referring to is the storm moving past us here, but then swinging sharply back to the NE, potentially even wrecking havok on N.O. in the process.

Phase 1 evacuation of Plaquemines Parish as of 9AM this morning.

Jefferson Parish is holding a news conference at noon, hopefully with the governor and mayor of NO... They will make recommendations at that time.

Contra-Slow is far off according to Jeff. Parish officials.... They want to give people time to move around. I did hear that because MS will need to evacuate too, that will present a problem for the Contra-Slow plan.

I am back. Katrina knocked out my power from Thursday to this morning at 510 AM. I took quite a few pics of it from my viewpoint in Kendall:

http://pg.photos.yahoo.com/ph/capefish1/...fish1/my_photos


We had tremendous flooding. I drove through Coral Gables and Coconut Grove afterwards and the amount of trees down was immense. It was unreal all the trees that were down. And many of them were on top of people's homes!

The last hour or so has seen the eye moving just slightly north of west on IR. The eye itself is looking ragged on both IR and WV, but it is probably just a cycle within the hurricane and in a few hours it will become well defined again. The system itself looks to be pulling itself into a tighter circulation. This isn't good news in my mind.

Waiting for the 11am NHC update.

N.O. lucks out a lot. I remember N.O. evacuating for Georges and then it missed them. They did the same for Ivan if I'm not mistaken.

ok..anyone got an explanation for the shift of the morning model runs to the east? I hate shifts to the east...and most models now are east of NO and starting to head for Bama.

Erin 95 , Opal 95, Ivan 04, Dennis 05, and that's enough!!!!

I do NOT like that trend.

My thinking is this: The earlier models were accurate. Then they shifted due to temporary changes, but they over-shifted. I hate it, but it's what I believe is true.

Katrina is still a bit uncertain, yes some parts near New Orleans are beginning to take actions. I'm not exactly sure where it will go. I have more doubts about Katrina than most others.

Model consensus from LA to the Western Florida Panhandle is the best guess at the moment.

The sat. pictures are impressive. It keeps growing in size. Impressive to see the outer clouds touching Florida, Cuba, and the Yucatan.

This is a very cool site, and I've enjoyed reading the discussions.

Guess what? Navy NRL's taken their normal track graphic off and stuck up a model track graphic!

http://www.nrlmry.navy.mil/tc_pages/ATL/12L.KATRINA/ssmi/gif/full/Latest.html

They identify the tracks at the ends, and they don't look good for NO. I have to say, there are some models that NRL has put up on the graphic that I've never heard of before. Perhaps internal Navy models?

Katrina is surely looking ragged now. Could it be a permanent trend?

The eye is still showing up on Key West long range radar. Two observations.

1) To me, it still looks like its moving 270.

2) Am I crazy, or does it seem like there are two eye walls forming?

11am update will be the deciding factor for metro NO.
