Gulf of Mexico Tropical Summary - GUTS IN on August 26, 2005


I'm going to provide a lengthy summary today, as we will have a major
hurricane threatening the Northern Gulf Coast in 3-4 days.


PLEASE LISTEN TO YOUR LOCAL OFFICIALS, THE
NATIONAL WEATHER SERVICE, AND THE NATIONAL HURRICANE CENTER
FOR ACTIONS YOU SHOULD TAKE TO PREPARE FOR HURRICANE
KATRINA AND PROTECTION OF LIFE AND PROPERTY


SYNOPTICS FOR KATRINA

<img src="http://www.diamondheadweather.com/gutc20050826.jpg">

First, the overall synpotics. The ridge over the ARK/LA/MS isn't going
anywhere fast. This ridge has dominated the northern Gulf of Mexico
over the last few days, and has not moved much at all.

A trough stretching fron Canada into Minnesota, extending into Kansas
is forecast by models to dig south. I do not see any evidence of this.
There is a relatively strong zonal flow from west to east across the
northern US. I believe that the trough will bypass or have very little
influence on the path of Katrina. The ridge has been underestimated
by many to some degree, including me. I did not expect Katrina to move
WSW to SSW as much as she did last night. The right turn the models
had forecast back into the peninsula does not appear to be a viable solution at all.

Here is the loop of this image so you can see the trends:

http://www.ssd.noaa.gov/PS/TROP/DATA/RT ... -loop.html


FORECAST PATH FOR KATRINA

<img src="http://www.diamondheadweather.com/guts20050826.jpg">

Katrina should continue moving west today and continue to get better
organized. Conditions in the Gulf of Mexico are ideal for development.
I expect that the path for Katrina will be similar to Ivan. Specifically,
Katrina should approach the mouth of the Mississippi, then begin an
eastward component. Katrina will approach the Northern Gulf Coast
as a MAJOR HURRICANE, likely a category 3, perhaps a category 4.
There is a decent chance for Katrina to become a category 5 hurricane.

The green area is my high probability area for the path of Katrina.
Areas from Grand Isle, Louisiana to west of Apalachacola Florida are
at the greatest risk for landfall.

Given the uncertainties of the ridge moving off to the west, I've
included an area in yellow that needs to pay careful attention to Katrina
until we get a better idea of the path, based upon the ridge.

Here is the loop of this image so you can view it:

http://www.ssd.noaa.gov/PS/TROP/DATA/RT ... -loop.html


GULF OF MEXICO SST'S

<img src="http://fermi.jhuapl.edu/avhrr/gm/averages/05aug/gm_05aug25_0217_mult.png">

It's important to see all of the fuel available for Katrina. As you can see,
the Gulf of Mexico has extremely warm waters, in the upper 80's to
low 90's. This is about as good as it can be for a tropical cyclone.
It's a big buffet of Katrina's favorite food to live on for the next few days.

GULF OF MEXICO 26 DEGREE ISOTHERM
<img src="http://www.aoml.noaa.gov/phod/dataphod1/work/HHP/NEW/2005237god26.png">

I've added the 26 degree isotherm so you can see that the warm waters
are significantly deep along the path of Katrina. This means that upwelling
will not quickly produce cooler SST's - thus a slow moving hurricane
will not "cap out" at any given strength due to a lack of warm water.


I encourage everyone from Port Arthur, Texas to Cedar Key, Florida
to pay close attention to Hurricane Katrina.


Footnote - if indeed Katrina heads my way, I will not be posting
WATS/GUTS/EATS, as I'll be boarding up. :D

Great GUTS dhwether, the strength of the ridge could save N. FL from another impact. Though it will be a Cat3 before your Cat2 plot on the track you have.

Well crud, I get all wrapped up in making this product and miss the
fact that Katrina is now a cat 2.

So add a category to each of my graphics.

The Cat 2 is 3, 3 is a 4, 4 is a 5.

Sorry about that, I can't control nature. :lol:

Thank you. I was so busy doing the extended GUTS, I missed the 11AM/11:30AM special advisory. So I just cranked all my numbers up a
notch. This is going to be a bad situation for someone in the northern Gulf Coast.

Sad to say I have to agree with your reasoning 100%. I just don't see anything coming along which could significantly impede the development of this storm.

Well Jan, Thank you. I value your opinion very much, you've got a
good understanding of the tropics. It is sad, someone is going to suffer
immensely because of Katrina.

Nice to see such a complete collection of graphics and thoughts like this. I think you're reasoning is dead on and, sadly, as you said, cat5 isn't anywhere near out of the question.

BTW, I like the "GUTS CHECK" title, but I guess it's the little things that amuse me. :D

Hey, I used the SST graphic you post often. :D


Also, I've updated the forecast graphic to reflect the strength changes.

Thanks to all for the feedback, I do appreciate it!

DH,
dwg71 posted the following in another thread. Do you see this happening now? It seems different from your GUTS.Thanks.

MV


Watch WV loop you can see the high pressure ridge centered over LA is moving W into East Texas. Cloud flow near Mississippi and the GREAT state of Alabama are moving due south and retrograding west. The trough in WY is now approaching th CO stateline. Everything appears to be happening just as NHC is predicting. Time will tell.

Great job, David. Looks to be sound reasoning, though I don't like the picture it paints at all.

It is different from my GUTS.

The ridge is moving, but ever so slowly. As I indicated, what the ridge does will determine where Katrina makes landfall. As of right now, the
ridge hasn't moved much at all in the last day or two.

With the relatively zonal flow across the northern US, I do not think the
trough will dig south and affect the path of the ridge or Katrina. Minimal influence at best.

Well, if I was really good with photoshop, I could make it really pretty.

Great forecast David. The movement of the ridge must be watched and I agree that everyone from Texas to Florida should be prepared. It is very disoncerting that it has strengthened so fast since coming back out over the water.

Thanks guys!

I found this interesting - a similar path to Andrew, perhaps? Except
south Florida got the "weaker" half, and the gulf coast will get the
hard core half.
