Hurricane Isabel is falling apart and fast. Re-Con planes have been flying in the storm since midnight and the entire west quad of the storm has disappeared. The eastern portion of the storm has a wind around 110KTS. There is discussion that re-strengthening will occour within 24 hours though so this still remains a threat.
Pressure has dramatically risen as well. Discussion currently is Isabel making landfall in either Northern South Carolina or Southern North Carolina and a due north move after landfall. Thinking is a landfalling Category 2 minimal 3 storm.

Wow, that's terrible.

It appears that the hurricane hunter has picked up teh formation of another eyewall....
To: ContemptofCourt
Yeah, on that link you posted, you can see a new eyewall forming in the last couple of frames - and the eye shifted NNW in the process. That could alter the forecast track.

Do you think that this will go back to Cat 3? I think that we should take a poll. Strengthen or weaken? Will it hit and where?

But Dover during a race day would be about the last place I'd want to be in a decent hurricane. Race WEEK in Dover is the last place I want to be even under the best weather circumstances - and I lived there for 21 years!!!!!

If the eye shifts more NNW would that make Issy favor a Wilmington NC landing more?

If the eye shifts more NNW would that make Issy favor a Wilmington NC landing more?It would do the opposite - shift landfall closer to Hatteras.

I think the storm is tapping into a flow off the Gulf of Mexico, and that could push the storm in a slightly more northward direction, as well as intensify it.

Washington Post article snippets:
"But for NOAA storm chasers hoping to further refine the agency's understanding and prediction of hurricanes, Isabel, he says, is a research dream.
"They are drooling . . . over what they're seeing in this storm -- things they've never seen in a hurricane before."
Like what?
"Well, last Friday they flew into the storm and photographed 'spokes' in the eye" -- streaks of cloud radiating from the center like spokes in a wagon wheel. "We don't know yet what they are or what they mean. But we're getting tons and tons of data" due to the opportunity to observe the Big One of hurricanes over an extended period of time.
When the Big One comes ashore, of course, it speaks with the voice of the Old Testament God. The one who gave the prophet Ezekiel the vision of the "big wheel."
"I started to use the term 'catastrophic' flooding and we decided against it," said NOAA public information officer Greg Hernandez. "We don't want to make people hysterical."
Though the storm's high winds will decay rapidly as it moves ashore, the spring and summer have been so wet along the Eastern Seaboard, Hernandez says, that the soil is saturated and all the streams are essentially full. Though every hurricane is different and researchers are still gauging Isabel's rainfall potential, such a storm would normally drop eight to 10 inches of rain during its passage, Kaiser said.
In addition, Isabel's forecast track -- in which Kaiser says NOAA has a high degree of confidence -- puts the Virginia capes in the storm's northeast -- or most dangerous -- quarter. This will allow the counterclockwise winds around the storm's eye to force a storm surge of 20 feet or more up the Chesapeake Bay and its tributary rivers. The bay's vast expanse of wetland will absorb some of this, but some sort of storm surge, Kaiser says, will be pushed all the way to the bay's tidal limits. On the Potomac River, this means Washington."

No, but I think it is done weakening...is survived the shear, the trough, and the dry air it sucked in...now it is moving into the gulf stream and it looks much healthier.

I'm telling you all - no one believes me, but this company in Florida is killing this hurricane with their product.
Check them out
http://www.dynomat.com They have done it time and time again with other storms.
I don't agree with what they are doing!
To: dirtboy
Are you thinking that this might skirt Hatteras and come up the Chesapeake like the models showed this weekend?
To: Howlin
Yeah, I read that...a bit optimistic I think. I think that the original prediction for a strong 2/weak 3 is valid. If it is moving at 30 mph once it hits, that will be bad for wind damage (but good for the rain forecast). Also, Izzy appears to be tracking right on the models....NNW for another 24 hrs, then a hook NW into NC.
