Jeanne Forecast #11: Central Fla bracing for a beating

#1 Postby Josephine96 » Fri Sep 24, 2004 10:18 am

EXPERIMENTAL HURRICANE FORECAST
HURRICANE JEANNE
NJN WEATHER CENTER
1115 AM FRI SEPT 24TH 2004

Hurricane Jeanne continues to swirl around out near the Bahamas as a healthy category 2 hurricane. Jeanne has also ever so slowly accelerated and is now moving at a 9mph clip. This acceleration if it continues may cause a quicker landfall for Jeanne.

Jeanne is currently moving into a possible area for marginal strengthening. Yes the waters are warm, even hot. But there is some supposed dry air that may try to wrap around Jeanne. Though I believe the warmer water will cause the dry air to cancel out.. causing Jeanne to possibly strengthen some more.

The current NHC path has Jeanne riding the coast and making a landfall somewhere in Volusia County. I believe the landfall will be a little further south, in Northern Brevard. Possibly around the Kennedy Space Center or Titusville.

Where and how Jeanne hits Fla all depends on the ridge and this alleged NW to N turn she could make as she approaches. If she rides the ridge the whole way.. it may keep her on a due west course and make her landfall much further south than projected. However, if the NW turn occurs.. This will be a Central Fla landfall.

After it makes landfall is interesting. Will it cross the peninsula..? or will it ride up US1/I-95 and keep the NE quad to the immediate coast. Yesterday I hinted that the storm may come inland enough where a N turn would come inland and perhaps make direct hits on the inland counties. I believe the potential of this still exists.

I also believe Jeanne will still become a Cat 3 by landfall. Yesterday I stated it could have 120 mph winds and I think that is also still possible. It all depends on the environment ahead of it.

Tropical storm force winds should be expected well ahead of Jeanne's landfall, they extend well out. These winds are between 40-73 and can still cause damage because they will persist for a longer period of time.

The other main hazard for now will be tornadoes. Tornadoes can develop in outer rain bands.. especially in Jeanne's NE sector. These tornadoes can sometimes be large.. as was the case with Ivan.

Finally.. This storms windfield may actually grow in size as it approaches the coast. This has happened before and could happen. This means TS force winds and maybe even hurricane force winds could be felt on the west coast. Everyone living on the I-4 corridor may get some impacts from this storm.

Here is the 5 day forecast on Jeanne:
Today: Approaching the Bahamian Island chain. Possibly moving up to a 10mph movement. Max Winds: 110 mph
Saturday: Watches changed to warnings by PM. Weather slowly eroding in Central Fla. Jeanne still out by Nassau and other Bahamian Islands. Max Winds: 115 mph.
Sunday: MAKING LANDFALL in Northern Brevard County as a Category 3.. probably before lunchtime. Max Winds: 120 mph
Monday: Accelerating near Jax/Savannah. Max Winds: 90 mph.
Tuesday: Just Inland of NC.. after making pitstops in Charlotte, Myrtle Beach, Charleston. Max Winds: 70 mph.

Track and intensity forecasts are subject to errors. Some as much as several 100 miles.

DISCLAIMER: This forecast is written by an amateur and should not be used in making critical decisions. Especially life or death decisions. For more details, please listen to local media outlets or the NHC.

As always.. comments welcomed :wink:

Also: IF ANYONE WOULD LIKE.. I am willing to attempt to forecast the winds {max} for all of Central Florida's Eastern Counties {Polk, Orange, Osceola, Brevard, Sumter, Lake, Marion, Indian River, Seminole, Volusia and Flagler}

Good forecast... but don't forget about the possible shear!! :D

I think you should place a little more trust in the NOGAPS and bring your landfall projections farther south.

J96...As a newbie trying to learn, why do you feel a NW path will occur when it seems that the high over Jeane is quite strong and even further west...Thanks for the help

Think your too far North

Northern Brevard County? I think this is based on GFDL East outlier. I think we can see some deepening in the ridge and some westward creep of the ridge. Hate to sound dramatic but the synoptics are setting up very similar to Andrew. Maybe some SW movement today with a Westward track into tommorrow. I agree Derek's forecast, a Broward\Palm Beach landfall with a pronounced move to the NW. The GFS based models were awful with Frances up till about 24 hours before landfall. They din'nt initalize the high's strength correctly and early enough. I would like to really see the algorithm of the GFS program. Is it predisposed to recurve storms and then discount that classic recurvature with external data?

Hey CL.. I'm a newbie too lol.. I actually don't really believe any NW turn may occur until it approaches the coast.. thus meaning it'd make landfall in Brevard or Volusia.. but also bring all it's winds towards the peninsula as well..

Here in Osceola where I am... I think the winds could easily reach hurricane force with gusts easily around 90.. But I'm not so sure yet..

Hmmm don't know. You'd have to ask a met.

For some reason the NHC seems to want to stick closely with the GFS and GFDL models, which seem to have underestimated the strength of these ridges so far this season. The NOGAPS seems to be doing a better job with that this season.

It is just my opinion, but this seems so similar to Frances when the NHC had it coming in at Jacksonville, then Daytona Beach, then Cape Canaveral, then Melbourne and finally Fort Pierce. The 11:00 AM track shifted slightly to the south and west and I expect to see it do so further later today.

THe NOGAPS has been excellent on jumping on the WESTWARD TRENDS ... but the end game result ends up being slightly east ... NOGAPS did so with Frances and Ivan ... (NOGAPS was the first to jump on the shift westward, but ENDED UP being TOO FAR WEST) ... Ivan, NOGAPS depicted a N'Orleans hit, when in actually, it was about 100 miles east ...

The NOGAPS has a leftward bias with TC's due to the progressiveness of the model ...

(That's from Stormsfury.. a pro met, NOT ME.)

I disagree... but we will see what happens Rocknole...

Do you think it'll come on shore where I have it Yoda or further north or south

Thank you Yoda.. :)

I'm going to TRY to put out another outlook tomorrow and even 1 early Sunday if I can get access to a comp.

J96..thanks for your forecast. A question: which Charlotte are you referring to? It would be an interesting track if this were Charlotte, NC.

I do believe I meant Charlotte NC.. Although I may have messed up.. Maybe it won't reach there lol

Strange tracks are occurring this year. Your forecast track may be correct! :D
