I heard on FOX last night that Ivan just may twirl around come back over Florida go out into the Gulf again and do it all over again. Ivan is making a High which is keeping Jeanne back but its that same high that just may let Ivan do this. The way they showed it on a map it was like watching a football game as they scribbled out what it cooud do, I mean go out into the Atlantic to a full circle and head downward then over

IVAN coming around again???

Article on Accuweather - Have We Heard The Last of IVAN
What´s left of Ivan is seen as a cluster of cloudiness off the Southeast coast. Showers and thunderstorms will move across Florida late Sunday night and Monday accompanied by gusty winds and locally heavy rain. Once out into the Gulf of Mexico, this feature could very well begin to regenerate and once again acquire tropical characteristics as it heads off to the west. This feature will then head toward the general direction of Louisiana and Texas by Wednesday and Thursday.

Today´s Discussion
POSTED: September 19, 2004 6:00 p.m.
1) Ivan. The remnants of the storm will cross Florida from the east Monday and be in the Gulf near 26 north and 85 west by Tuesday morning. 10-15 foot seas and gales will hit the northeastern coast of Florida late Sunday night and Monday. The system will re-organize Tuesday could be a 50-60 kt tropical storm by Thursday. While we are assuming that it will be renamed Ivan if in fact it develops, there is always the possibility it will be given a new name, in this case Matthew, since the Tropical Depression in the eastern Atlantic will be named Lisa within the next 24-36 hours. Regardless of the name of the system, or it´s speed of movement, it appears the Texas or Louisiana coast might have to deal with it later in the week. 2) Jeanne. We are at odds with our good friends at TPC. First of all, Jeanne may still be on the charts and near the coast next weekend. I feel it will perform a loop by Wednesday and start back for the coast, and there is a chance, given the pattern that it could impact U.S. weather next weekend. I also do not see any reason why this storm will not develop to a category 2 or perhaps greater hurricane. Actually I do see the reason, but it is based on the United States model, which whips it out to sea in the first place. The bulk of non U.S generated models have the loop and it fits a nice analog, though further east in the end game, to Betsy in 1965. The call is a loop and a move back toward our coast in the Wednesday-Friday period with possible impact late next week. 3) Karl will recurve and not hit the states. 4) Lisa should develop over the next few days from Tropical Depression 13, but it is too early to say whether it will suffer the same fate as Karl or come farther west.

IS BASED ON SATELLITE IMAGERY...WEATHER OBSERVATIONS...

BASED ON 1800 UTC SURFACE ANALYSIS (http://www.nhc.noaa.gov/tafb/ATSA_18Zbw.gif) AND SATELLITE IMAGERY (http://www.goes.noaa.gov/browsh.html) THROUGH 2315 UTC.

SATELLITE SIGNATURE HAS CHANGED LITTLE DURING THE LAST SEVERAL
HOURS. THERE WAS A BURST OF DEEP CONVECTION NEAR THE CENTER
BETWEEN 1900-2100 UTC BUT CLOUD TOP TEMPERATURES HAVE SINCE
WARMED. CURRENTLY JEANNE IS PRODUCING AN AREA OF SCATTERED TO
LOCALLY NUMEROUS STRONG CONVECTION NE OF THE BAHAMAS FROM

I do not trust the NHC at the moment and neither should you
If it is one thing you should never offer as advice on these boards...it is that. For your information...the National Hurricane Center is the RSMC (Regional Specialised Meteorological Centre) for the Atlantic Basin as designated by the WMO. Not Accuweather. In fact, time and time again, NHC has been MUCH MUCH more accurate than Accuweather, which overhypes systems. Yes, once and a while they get lucky, but for the most part the NHC does a fair job.
I do not want to hear one more person on these boards say that again. The NHC is the place to go for accurate, up-to-date information and area warnings. Believing otherwise could lead to false information causing unnecessary panic or falsely believing a system will go elsewhere when it is heading straight for you...a very dangerous thing.

Please pay attention if in potential cone.... always we should heed the advice of the NHC -- they are the experts and have access to more information than we do. Please do not ignore their information and advice!

Unlike AccuBlunder, NHC actually knows that Pensacola is in Florida, not Alabama. You should take that into consideration.

Slipping? They continue to improve. And they're clearly obviously better than AccuBlunder.

This is really strange -- someone who joined last weeks and has two posts telling people to ignore and not trust the NHC? OUTRAGEOUS.
Are you trolling? This is the kind of statement that is dangerous and really pisses off the people who are here for serious discussion. Please keep in mind that there are people here with NO specific weather knowledge, and the LAST thing they should be told is to doubt or ignore the NHC. The experts here know how to weigh and interpret NHC forecasts and advice; they are the only ones that can create independent forecasts.
IMO, your post is irresponsible. A moderator might want to comment.

100000% in total agreement. Could not have written it any better than that.

Derecho,
You know that was just a graphics error and only slightly off at that. I'm sure everyone is aware of that especially those that live in Pensacola. Joe B. was the first to start talking about the ghost of Ivan. Then when the models started leaning that way the NHC jumped on the band wagon. Now I agree that the NHC should be what one listens to when it comes to watches and warnings but I do not believe accuweather deserves the bad rap it's getting in this thread. They are professional meteorologist also, and do a pretty good job. If you read their forecast when it is dealing with a hurricane they put a disclaimer saying you should listen to your official nws forecast, as they could be liable to a law suit if they didn't. I've read Joe Bastardi's article where he talks about this. Accuweather trys to give different perspectives of what could happen days away based on models and their old fashion forecasting methods using analog years and where the highs and lows are. I believe the models are too heavily relied on sometimes. My God, they were all over the place at times with Ivan and Jeanne.
