I feel sorry for everyone in this storms path, I know how it feels. Frances did not hit us as a hurricane in SC or NC but the tornadoes spawnded from that storm were bad enough. Hope everybody here are blessed.

WOW!!!

Truly freaky! Short term turn for sure, but a boon for not making landfall.

Wonder if Ganja had anything to do with it?

Never say never, 2004 is the year of all the rules being broken.

Jamie, I think they have so much data coming at them, they don't know which way to go with it. The local TV met called me earlier, and he basically thinks the same thing. The phrase they put in the last discussion, was a "nice" way of saying we aren't sure either. It was close to a "No Duh" phrase.
As you have seen the tracks walk east and west all week. Any track west of the penisula would put Ivan along the coast. As Frank and others have pointed out in the probabilities post, on the other thread, the 65nm of a point is basically 1 degree of latitude or longitude. Wouldn't take too much variance off track to get the whole coast in the picture.

There is no way it's a Cat V (at FL landfall). I would guess II to III. As far as how much it would weaken, see Charley. ( i.e., not much)



Well, Charley did weaken, but from a cat IV to cat II - still strong enough to snap trees and destroy mobile homes. You can expect about a two category drop when a tropical cyclone moves inland, depending a lot on topography and time spent over land.
Whether Ivan makes landfall or not, it is bound to be close enough to the west coast of FL for MANY coastal residents to feel a major impact!
NHC is doing a great job for public safety - better to opt for the west coast track at this time - note that the entire peninsula of Florida is still within the "cone of concern." At this point in time, who cares about the point of landfall?

I'm a little confused tonight as to where the forecast is going with this Hurricane. I see the NHC sticking with a track to the panhandle, and then I see Joe B insistant on a West Coast landfall, along with the Accuweather forecast. I do respect both forecasts but each has different implications for the peninsula. What is it that NHC sees that JB doesn't or what is it that JB sees that NHC doesn't? What do the other Mets thing about this? (Ed, JK, Clark and others).

And as for this " A SLIGHT CHANGE TO THE RIGHT OF
THE TRACK COULD BRING Ivan INLAND ANYWHERE ALONG THE WEST COAST OF FLORIDA." .




I addressed this in the previous forum but my reasoning was quickly drowned out by "The NHC wouldn't do that on purpose!" I stand my ground.

I believe it is a case of Psychology vs. Meteorology. I believe the NHC considers West coast of FL most likely landfall area. But in order to say so, they have to plant a "dart" somewhere on the map. When that happens, the rest of Florida relaxes somewhat. I don't believe they feel confident enough of any landfall site to allow the rest of FL to let down their guard even a little bit. Remember Charley? Folks screamed loudly "We thought it was hitting Tampa!"

Just my .02 cents on this. Joe Bastardi can afford to be a little mouthier than the NHC. Too many lives are in their hands for them to possibly lead some into complacency anywhere along the coast.

yeah that SW wobble very noticable on the IR loops.... might be the difference in some areas of Jamaica getting say 120 mph winds as opposed to 150 plus.... won't know till we see the damage reports.... still bad enough as it is

wobble could be caused by interaction of Ivan's overall flow with the mountains of the island and causing it to shift left a tad... or perhaps the ridge is still hanging in there.... do believe at the moment the system is a little south of the official forecast track... as was posted earlier, right after exiting Jamaica start looking for that discernable NW track... that's what the models are predicting... find out soon enough...

Re: The "Southward" turn

Could it temporally be the path of least resistance? I see the Atlantic Ridge holding firm and to the West nothing but Westerly flow.

I donno... I just hope Jamaica spared a bit.

Richiesurfs: I wasn't implying that Jerve or Terry were NOT agreeing with the NHC, in fact they mentioned several times (maybe several HUNDRED times) that the NHC had done a terrific job with the very hard to forecast storms. VIPIR is a local model that only forecasts 48 hours out. That being said, Channel 8 would show the NHC track first and then the VIPIR track and the VIPIR track was more accurate with future paths hour to hour...not off the NHC's track by much, but it did a great job of forecasting. I don't think that a statement by a local met stating that he thinks it may be a little further east than the official track is wrong, as "a little further east" is in the "cone". If you remember, Bryan Norcross was the ONLY one who went on the air to tell Miami residents that Andrew was headed their way ---something the NHC did not "forecast" --- and he was right. Just because these mets don't work for the NHC doesn't mean they're any less qualified to give a forecast. It's not like the NHC's saying "Texas" and he's saying "Tampa".
Tom Terry did a great job with Frances with the model they used. When the NHC was showing a near miss ala Floyd, Tom followed the path to a tee. Only when it was apparant that it WOULD hit Florida did he show their model..which turned it more west, making landfall almost exactly where he said it would.
I just wanted to clear that up.

Absolutly!

Probably the worst case for Florida is to grind up the West coast. While a "quickie" entry-exit across South Florida is becoming less likely, it might be the least damaging.

It's weird thinking like this, but maybe it's the Panhandle's turn to take a hit for the state. The bulk of the state has been ripped so far. I truly hate to wish it towards anyone!

Just a reminder of the link to Florida's Storm Surge Zones, Evacuation Routes, etc.
If Ivan accelerates northward along the west coast, look for a higher storm surge, esp. at high tide.

Re: Satellite Eclipse [Re: jmm045]
      #25186 - Fri Sep 10 2004 11:56 PM

For those that are new to the board. The satellites will be entering an eclipse with the Sun, from about 04Z to 0615Z.
That's 12am to 215am EDT. The image may appear to be updating, but if you check the timestamps on the pics you will see that most stop at 0345Z or 0400Z. Depending on your source. The loops will look as Ivan is stationary, when in fact he's not. The sats should be back up between 0230-0300edt. As it takes several minutes for the imagers to power back up.

Just saw a sat shot from Jamaica on or local ABC affiliate(WSB-TV) and Ivan has made landfall, it looks like near Kingston I believe...

It's time to really remember Jamaica in our prayers right now.

Like I said yesterday.....
Godparents in Sarasota.......Charlie
Mom, grandparents, aunts, etc in Vero..........Frances
Inlaws have a beautiful beach house in PCB.......Ivan?

Granted, these weren't "direct hits", but certainly close enough. Plus, if Ivan does go up to the panhandle, and into Al, there will be serious destruction. Anyone ever take the trip to PCB from ATL via Hwy 431?

I for one am tired of seeing VIPIR inappropriately compared to NHC forecasts. It is a great visual tool for the short term (6 hours) because it's a radar and weather feature perpetuation tool. If you were watching closely, VIPIR was all over the place for Frances. It kept taking Frances north up the east coast when Frances stalled. Only when Frances started moving a little faster toward FL did VIPIR show a more reasonable short-term movement. Notice that VIPIR has a bias to move broad circulations toward the NE.
Sorry I couldn't resist to add my .02.
