Party like it's 2005

Tropical Storm Isaac might hit New Orleans. Brendan Loy is reporting:

Isaac A Major Threat to New Orleans; Is Anyone Paying Attention?
As Tropical Storm Isaac continues to churn�and struggle a bit�in the waters off Cuba, Hurricane Watches are up from southeastern Louisiana to the Big Bend of Florida, and the �ber-vulnerable city of New Orleans has moved inside the NHC�s cone of uncertainty. Three of the best American forecast models � the GFS, HWRF and GFDL � are in almost lockstep agreement this morning that Tropical Storm Isaac will track toward southeastern Louisiana over the next 60 or so hours. Here is what the GFS expects last Tuesday night � an intensifying, borderline Category 3-4 hurricane coming ashore on a near worst-case track for the Big Easy.

Despite all this, I get the sense that most people aren�t paying attention. Last night I noted that Drudge and NOLA.com still aren�t focusing on the New Orleans threat; well, they still aren�t. Moreover, Twitter searches for �New Orleans evacuation� and �Landrieu evacuation� (Mitch Landrieu is NOLA�s mayor) turn up almost literally no discussion. Not only have evacuations not been ordered yet, it seems nobody is even talking about the possibility. I keep seeing tweets from people who seem genuinely shocked when they learn New Orleans is under threat, like this is something nobody is discussing. Ugh.

Yet 48 hours from now, conditions could be starting to deteriorate in New Orleans. And pre-Katrina studies indicated it takes 48-72 hours to evacuate the city. WAKE UP, PEOPLE!! WAKE UP, MEDIA!! WAKE UP, GOVERNMENT!! This feels like 2005 all over again, in terms of the apathy and inattention at this stage. Isaac might not hit New Orleans � it might very well go elsewhere, I want to emphasize that � and it might very well not be as strong as feared (more on that below). But you don�t make preparations based on wishes and hopes. You make them based on realistic worst-case scenarios. The realistic worst-case scenario for New Orleans right now is really bad. People need to start paying attention to this!! If I lived in New Orleans, I�d already have packed my bags overnight and I�d be getting the Hell out of town this morning, as a precaution. The worst thing that can happen in an unnecessary evacuation is, you get a mini-vacation that proves to have been needless in retrospect because the storm doesn�t intensify much, or goes elsewhere. That�s a lot better than the worst thing that can happen if you stay (or wait too long to decide to leave), and the storm hits. New Orleans, remember, is largely a below-sea-level bowl. If you thought the levees breaking was bad, wait until you see what happens if a storm comes in on a sufficient worst-case track to overtop the levees. The long-studied worst-case scenarios for New Orleans are horrible.

Before I quote the NHC�s 5:00 AM advisory, I want to say a word about the uncertainty of this forecast, regarding the storm�s intensity in particular. Lest anyone believe I treat these computer model intensity projections as gospel, my personal feeling is that I�ll believe the modeled extreme strengthening when I see it actually begin to happen. Isaac has shown a tendency to underperform its intensity models thus far, and the waters in the Gulf aren�t as conducive to insanely rapid deepening as they were in 2005. I�d be pretty surprised if Isaac ever becomes a Cat. 4 or 5, and while I think Cat. 3 is very possible, I think a Cat. 1-2 type situation is also very possible. But again, planners, and folks in harm�s way, must assume the worst! I�m seeing some comments from folks dismissing the threat of a major hurricane as �nonsense,� or hype, given the storm�s current state. That�s ignorant. Don�t mistake your own suspicions and educated guesses for a scientifically unimpeachable forecast that people can rely upon when making life-or-death decisions. Isaac MAY VERY WELL NOT strengthen as much as forecast by the computer models, but that doesn�t mean we can dismiss and ignore those models. We must take them seriously, because what they�re predicting COULD occur. Rapid intensification can and does happen. Isaac wouldn�t be the first storm to look this disorganized, then be a major hurricane two days later. Will it happen? Again, we don�t know for sure, and I�ll fully believe it when I see it. But it�s not some crazy, hype-driven �nonsense� idea. To claim otherwise is not only ignorant but downright dangerous. That sort of false sense of security can literally kill people.

Pragmatic words. I would be getting my bug-out-bag from the garage and putting it into the truck if I lived there. Fortunately, the present governor is a lot better leader than Blanco and will not take three whole days to ask for Federal assistance. I am betting that Jindal has already requested aid.
