The 2008 peak of hurricane season is ramping up with Gustav and Hanna. The two storms pose threats to the U.S. At least 22 deaths in Hispanola are attributed to Gustav to date, and a Hurricane Warning is in effect for Jamaica. Tropical Storm Hanna has formed in the Atlantic.

alot of people seem to forget that, New Orleans dodged the bullet, on the good side of the storm, it was two levies breaking that put New Orleans under water not Katrina. Ms got hit much harder. Gus, if the track holds will be far far worse for New Orleans then Katrina.

I have been and will continue in earnest.

A dear friend of mine is involved in evacs of hospitals (as he was for Katrina) and provided the model for how to do it right.

What are we talking about for max surge?

[rodguy911]

Too much crack!

They should visit the aquarium in Chattanooga. There are a number of War of Northern Aggression battlefields within a fairly easy drive. I guess what I’m suggesting is something to take off a bit of the stress.

Pressures seem to be running a little high on this storm so far ... the windspeeds we've seen would often correspond to lower pressures. I also think we're likely to see another period of pretty good intensification through the first half of the Gulf. I wouldn't be surprised to see pressures as low as 910mb or so at some point.

Did you guys see him just now on FOX? I swear the guy is on downers.

GOOD to see you jeffers:) How’s dad?

I remember him after Katrina too- he’d just be...gone.

“Hurricane Andrew must have been some force to flatten whole groves like that.”

Actually the wind strips the leaves and some species of mangroves cannot recover. We have the same thing going on on Charlotte Harbor. Check out aerials before Charley and now.

Happy to have you subscribe if you like.

Oh, btw, it comes with the unlimited to calling or e-mailing to ask questions or inquire about optimum ways to use the data (free, of course). And, we're adding two new sections, probably next weekend, including the ability to optimise crossover moving avgs vs price. Lots of pricey programmes offer this (naturally, it's not difficult to add), but no reasonably priced website does, afaik.

Thanks, I will pass those ideas onto my son. His girlfriend will be busy doing Americorps stuff at the shelter, but he’s not with Americorps so he doesn’t know if he’ll be doing anything there or not. Exploring may be just the thing for him.

Wow! Thanks for posting that. Can’t believe how much you learn here on FR...

[rodguy911]

Is 910 in the 26’s or 27’s. I know baro measures better than mb.

[rodguy911]

Sounds great I will get with You later.

” Police with bullhorns plan to go street to street this weekend with a tough message about getting out ahead of Hurricane Gustav:”

Gustav will likely pass and then the next time nobody will leave and they will get hammered. I never evacuate but remain completely prepared.

They had only made it 125 miles north in Mississippi when they called a couple hours ago.

125 miles is excellent progress!

She's really ticking me off. At present, its looking like she's going to stall near the Turk Islands from Sunday night midnight to about early Thursday morning.

The issue that's holding her up is models are forecasting a backing ridge falling in behind Gustov (stretching out from high pressure centralized in the Great Lakes region. In conjuction with this is a mid-Atlantic high about 70W, 30N that seems to be positioned fairly solidly. The backing ridge will hold up Hanna from moving west, and the mid-atlantic high will dictate her N component of motion.

I also noticed that the 1000-5000 THK [576] isopleth appears to be in play with respect to her motion. While its lattitudinally parallel, she's stagnant, but when it inclines SE-NW she begins to move.

Right now, once the backing ridge weakens, she'll begin to move NW. Presently its lookin' like Miami to Titusville will be spared most of the carnage. It looks like she may take a track just north of the Bahama Island chain.

Valid 08090500z:

Darkest streamlines are about 50kts.

Projected wave heights:

Darkest red shades zone >35'.

By 08090512z:

Darkest red zone >28' (<35').

They just changed the voluntary West Bank evacuation into a mandatory one... “leave no later than 8 AM tomorrow”... “NHC calling for the impact to be at or near the worst case scenario” ... “If you remain behind, you are confined to your home. If you are found out of your home, you are automatically considered suspicious.”

Doesn’t look good for New Orleans. Hope all there end up safe.

My local Charleston station forecast for Hanna was just on. If it makes it here at all it won’t until Thursday or Friday. New storm tracks are all over the place. The only track they don’ have projected is it heading East. Yes it could also stay on a southerly track and go into the Gulf.

I remember that! I feel better knowing there are so many good and qualified people assisting with preparation for this potentially devastating event.
