Isidore could become major disaster for Gulf Coast

Although the MRF isn't exactly the only model used to forecast for hurricanes I will use it as an example. According to the latest run the Isidore(either in cat. 4 or 5 strength) would impact New Orleans and then sweep along the Gulf Coast of Mississippi, Alabama and the Florida Panhandle. This would impact Mobile and Biloxi/Gulfport with extreme damage and New Orleans might not exist anymore. New Orleans was built below sea level. It can't handle more than 5 inches of rain without flooding. According to the MRF's latest data if Isidore followed the solution the MRF lays out there would be 25-35 inches of rain impacting New Orleans.

The damage from the rain alone would be catastrophic. Add in cat 4-5 winds and sea surge and we are looking at a hurricane rivaling Camille's power and much much much more destructive than either Camille or Andrew. While the MRF and other models disagree, this forecast is something that has to be prepared for now. A large cat. 4-5 hurricane impacting the areas listed above would cause unimaginable damage. The loss of life if proper mandatory evacutation procedures aren't enforced could be overwhelming. Not all models are predicting this much of an extreme northern turn. Over the past few days more and more models are starting to pick up on a trough turning Isidore to the North. Over the past two days only one model had been predicting this and now 4 out of 6 are. This change in data and Isidore's strengthening could spell disaster.

Not to push any panic buttons but my guess is that New Orleans is long overdue for a massive hurricane. Turns out this one might just be it.

Even if it tracks further west, like South Texas needs any more rain this year.

Hopefully it won't hit NO, but I'm holding my breath just in case. I'm still going to bet on WNW though, with a Texas landing; maybe it'll wipe out Bush's vacation home.:p

Edit: No, I don't hate Bush, just making some humor. A Hurricane is a scary thing for many people; finding some humor in it is good for everyone

Wouldn't it be nice if a big storm came by and hit your property instead?

Well, seeing that the entire southern portion (that peninsula which extends into the Gulf) of Louisiana is being reclaimed by the ocean at an alarming rate because the Mississippi no longer flows freely enough to carry the sediment which created the lower portion of Louisiana, threatening not only New Orleans but a vast network of natural gas and oil pipelines which account for approximately 18% of the natural gas and oil distribution network in the United States, numerous companies and communities, and nobody seems to want to do anything about it, maybe the hurricaine will accelerate the process and cause New Orleans to fall into the Gulf of Mexico.

Thankfully Isidore just passed us by to the north of Cancun. One thing about hurricanes, they quite often don't track as predicted. This one could easily turn south into the Mexican coast or wander over towards Veracruz. I don't see it likely hitting NO; I think landfall will be south Texas or north Mexico.

Welp, it made landfall on the Yucatan Peninsula, and is currently weakening, as the eye is still over land. However, the projected path has it aiming for Texas/Louisianna(sp?). If the projected path is right, it could very well hit Major Storm status again, hitting the warm Gulf waters, before slamming in to the SE.:(

Dammit, I still haven't been to the Mardi-Gras. This is BS. I was planning to go to NY and see it from the top of WTC, and then 9/11 happenned. Now I want to go to NO and see the Mardi Gras, and you are telling me it might not be around anymore. This is BS.

Right now it looks as if Isidore would pass to the west of New Orleans. This is a larger than normal hurricane so damage would still occur. A lot of models are beginning to move the track farther eastward which would put NO under the gun. We will have to wait and see.

I forgot to mention that the intensity forecast for Isidore has been reduced. It is been over the Yucatan for so long that the inner core of the wall has collapsed. The Gulf is ripe for reintensification, but not sure how long it will be allowed to strengthen before it gets grabbed to the north.

My forecast for right now is a cat. 2 Hurricane impacting anywhere from Central LA. to Destin,FL.

My best educated guess is Mobile or NO.

Ugg, I'm enough of a betting man to not like those odds when it comes to just how little NO can take(better than 50/50 on a <240mi crossing; and this sucker is big). Hopefully, it'll move north quickly, otherwise it may really ramp up once more.

The locals where I live and work are already comparing this storm to the way Opal behaved. Wonderful!

It's still on land, when is it expected to hit the waters again?

Well, to answer my own question, the latest projection looks like it'll hit water by noon tomorrow, with a path that more or less encommpasses LA.:Q This thing really has it out for the SW.

The MRF/GFS is a crappy model. Stick with the Canadian or European ensemble. ;)

I want Isidore to hit the US hard. Not the coastal cities, mind you, but bring this damn storm up the Applachians and have it dump inches upon inches on us. The local reservoirs are full of mud and cracked earth.

Really thinking the models have been missing the mark on immediate impact. Isidore is stationary over the Yucatan(no telling how much rain and flooding now) and still isn't moving north yet. As with all hurricanes you never can really predict how much it will strengthen. There is weak vertical shear so condtions for redevelopment are good. The water in the Gulf is 5-7 degrees above normal. Opal strengthened from a cat1 to strong cat4 hurricane in less than 24 hours and then dropped back down before it made landfall.

All the models are in agreement that NO will get a direct hit. The intensity and speed of the system is what is up for grabs. If Isidore has time to regenerate(if it ever gets out of the Yucatan) and moves slow enough before the system grabs it up north it could hit NO as cat 1-4. Since the eye has been pretty much destroyed it might be hard for it to regain a lot of strength. Expect Isidore to become a depression on the next HH report. This storm is iffy and could be potentially dangerous if it can reform.

I don't even want to thing of the rainfall it has dropped over the Yucatan. I would hazard a guess at 40+ inches of rain.

jjones may have more info about the rain than I can get as he lives in Cancun.


As for now my prediction is that it will be a minimal hurricane and NO will dodge the bullet again(as far as major 'Canes are concerned). While NO will take a direct hit, major redevelopment will have to take place for damage to be extreme.

The other possbility is for Isidore to die over the Yucatan and be brought into the Gulf and SE U.S. as a non-tropical storm.

We will see.

The MRF/GFS has been more accurate with this hurricane than the Canadian models or UKMET.

Shocking! A hurricane in the Gulf? No way! :p

Shh. People who live there are just going to have to live with it, I guess. It comes with the territory.

It's like the people who build houses in 50 or 100 year floodplains, and then whine because it floods. Duh!

At least we can predict weather systems somewhat correctly now. It's not like people will have no warnings. Darwinian theory at it's finest... Only the fools who refuse to leave will die. ;)

I'm from Biloxi. Remember that the worst part of the storm is on the north east side. If this thing hits NO, Biloxi will get smashed. If it hits south of Baton Rouge, New Orleans will get the brunt of the storm, something I don't want to even think of. Let it hit Mobile. ;)

This storm looks like it may be interesting to watch

It looks as though the most recent projected path info
shows it bearing in more on NO than ever Linkage

I live in Missouri and if this sucker holds up it looks as though we may even see some rain outta this one....

Well, I for one know that I'm particularly concerned about the storm, seeing as how i currently attend the University of......New Orleans. Actually, it's raining as i type this, and there's talk of an evacuation later on in the week. Hopefully, Isidore will die down some and not wreak havoc on the city...
