I can't see this doing anything but moving due north or even NE. At this time, I see it as a Florida landfall. What am I missing?

Being in central Fla, I'm gonna clear out of here and let you Gulf coasters make your plans.
Stay above the water line if you're in New Orleans !!
Phil, I think of course a western edge hit in New Orleans would be worse but I believe that if the storm is East of them, the North to South Winds would move the water from the Lake down toward New Orleans. I think it's bad in either case.
I'll be listening to WWL 870 on the am dial to see what the locals are saying tonight and tomorrow.

Stay safe everyone.....

Scotts Post... [Re: Wxwatcher2]
      #26888 - Tue Sep 14 2004 03:28 AM

As i posted many times the runs of the 18Z,,which are 2pm are used for the 11pm update here. The dont have the oz run which is 8pm to give out and when they do it will be at the 5am update. Also the Bamn models that you will see at 6z and 2am eastern will be run offs of the GFS run tonight at 0Z. So movement tonight into tomorrow and 0z runs will be key.

This was from Scottsvb...I'm outta here!

Everyone be safe!

Good post Spock. Bastardi, not usually a follower of the ETA, has had more confidence in the simplistic models than the GFS suite (AVN, GFDL, etc.). He believes their right-bias is directly related to their inability to handoff heat from the tropics to the temperates. He mentioned the other day that the Accuweather international guy said the GFS was the KING of South America because they don't have as many temperature variables there. Lemme go make a run and see if he's got a nightly update (he had previously called for a mouth of the river hit and a Camille track, but that was prior to the NNW jog). - No update from Joe. The mid atlantic model maps have been updated at 11:00. Models are really beginning to cluster on the MS coast. Be ready out there!

Hey guys, havent been able to post all day, I've been very busy. Tomorrow evacuations start around here, me and my bro are gonna help my boss board up his buisness in the morning. Were going to evacuate from Gulf Breeze and head to Pensacola and ride it out with my dads bosses family at his print-shop. We'll be way above see level so Im not worried bout surge, but winds are a different matter. I have had the weirdest feeling lately, Im excited, but also scared by all this. This will be a first for me for sure. My whole neighborhood is boarded up except us because were only renting right now and we arent responsible for the house but Im praying it holds up ok. Well Im off to get some sleep, tomorrows gonna be busy. Wishing everyone around the coast luck with this one. Cheers GOOD LUCK EVERYONE.

Re: Storm Surge and Waves [Re: BabyCat]
      #26892 - Tue Sep 14 2004 03:35 AM

The east Gulf buoy, 242nm North of Ivan, reported 11.2ft waves, wind 25kts gusting to 29kts at 0250Z.
This is only the wave height. The storm surge will be in addition to this. I would say 10-20 feet surge on top of 11ft waves. That's 3 stories of a building!!
BTW-the wave ht was 9.8 ft an hour earlier. That's an increase of 1.4ft in an hour, at 200+ miles out!!

Thank you, and I must say, after dealing with the LFM for years, the ETA looks great comparitively-but, it still has its problems. I remember a forecast I had to make up in NJ where the LFM called for 18 inches of snow, and the NGM nothing. Nothing won. The rule of thumb was to halve the QPF. Now, the GFS is the one with the gridscale feedback problem.
Having said all of that, I actually like the GFS a lot, but I must acknowledge its recent difficulties, especially since its bias was usually the other way.
One last thing on the ETA-I think a couple of years ago, they made adjustments to the model to try to improve its forecasts. That may be so, but it still seems to have trouble with tropical systems.

Bad news..the more you learn.
Hope it falls apart at the coast like that one last year (or the year before) that hit La.
It's been a CatV a long time now and over 24hours with *lightening* in the eye wall. Can't stay that intense for much
longer, one can only hope...

Wow those models are starting to cluster. This looks like what happened for Frances when the models all of a sudden came together and were pretty accurate. Also, I do alot of investigative interviews and have developed an ability to read body movements and mannerisms. Looking at Dr. lyons, he shows much more confidence now in where Ivan is going. I think they have a pretty good handle on this now. The question now becomes intensity. He also says that it may speed up and lessen the time allowed to weaken.

If I lived in the Gulport to Pensacola area, I would get the heck out of town...NOW.

Keys are windy [Re: DroopGB31]
      #26901 - Tue Sep 14 2004 03:44 AM

Being a native Floridian, I understand that storms, even severe weather is an everyday part of our locus here. I applaud the county for evacuating the Keys, but I am still uncertain whether lifting the evacuation notice was such a good idea yet. They have had torrential rain today and I've heard the traffic heading towards the islands is a nightmare. Also, according to the Sand Key data buoy, they are receiving sustained winds of 26kts (30mph) and gusts up to 31kts (35.6mph). Those are pretty strong winds to have multitudes commuting over wet bridges.

My thoughts and prayers are with everyone in the path. Please take all precautions necessary to preserve property and life.

Kyle

I must be missing something here- I just can't seem to understand why the forecasts are all west oriented right now. Perhaps I am mistaken, but from everything I have seen and heard, it just seems as though the storm could hit any little bump in the road and everything could change in an instant- much like the shift from Central Florida to the Panhandle. I just see a more easterly route before it is over with. Again, am I missing something from the satellite images or the current flows? Until Ivan is gone, my plywood stays up (I stayed at the Home Depot ALL night to get it, so I at least have to admire it for awhile).
