She sure appears as though she took a very slight NNW jog in between 18:45 and 19:15 UTC.

Current radar shows dry air very near the center on it's west side. We'll begin to see some weakening now.

Hello, VYS!

Before starting on Fay, you have the best take on- Russia finally returning fire
on the US -that I've seen so far.

And the only thing that could take me away from that is a Tropical Storm.

Fay's one of the most fascinating I've ever seen.

http://www.ibankcoin.com/peanut_gallery/...st-ever-on-fay/

veritas5 has some interesting ideas. Like Okeefenokee getting 20 inches.

It could use it.

Keep up the good work,
James

In Palm City FL winds have picked up more in the last hour or so to some of the strongest feeling we have had all day. I guess we are on the east edge of some of the deeper storms left around the eye.

High pressure building....Fay will head west soon [Re: Storm Hunter]
      #82317 - Tue Aug 19 2008 08:29 PM

Looking at the water vapor loops...and the latest water vapor loop from the NHC....Fay is not wobbling. She is being affected by the building ridge. The trough weakened and lift out totally...and she is now gonna be kicked back west.

Does anybody else see this...

The most recent Floater vis sequence looks like Fay has made a jog to the NNW, but I don't see that on radar loops. Wobble?

Check out this GOM Water Vapor loop. Why is there such an elongation in the wind field pattern to the west?

Guess this answers my earlier question:

Via his blog Dr. Jeff Master has referred to Fay as "unprecedented" and then added "I can't ever recall seeing such a large pressure fall while a storm was over land." Even he seems stumped by this turn of events, commenting "To have a storm intensify over land and maintain that increased intensity while over land for 12 hours is hard to explain".

And yet the crazyness continues as the models seem to be coming together, thus the NHC is now showing Fay has a good chance of making a THIRD landfall in northern Florida.

This seems to back my comments of a more northerly component as of late:

TCDAT1
TROPICAL STORM FAY DISCUSSION NUMBER 17
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL062008
500 PM EDT TUE AUG 19 2008

FAY DID NOT WEAKEN OVER LAND AS ANTICIPATED AND IN FACT...IT IS
STRONGER THAN IT HAS EVER BEEN SO FAR. INITIAL INTENSITY IS
CONSERVATIVELY SET AT 55 KNOTS. THIS IS BASED ON SATELLITE...RADAR
AND CONFIRMED BY SURFACE OBSERVATIONS. THIS HAS PROMPTED A
SIGNIFICANT CHANGE IN THE INTENSITY FORECAST. GIVEN THAT FAY HAS
KEPT SUCH A WELL-DEFINED SIGNATURE ON RADAR AND ON SATELLITE...THE
CHANCES THAT THE CYCLONE BECOMES A HURRICANE AS IT MOVES OVER
THE GULF STREAM EAST OF FLORIDA HAVE INCREASED. THE INTENSIFICATION
IS SUPPORTED BY SHIPS...THE GFDL AND THE HWRF MODELS...AND IS
REFLECTED IN THE OFFICIAL FORECAST.

THE EYE FEATURE ASSOCIATED WITH FAY HAS BEEN TRACKED BY SATELLITE
AND NWS DOPPLER RADAR AND THE BEST ESTIMATE OF THE INITIAL MOTION
IS NORTH-NORTHEAST OR 020 DEGREES AT 7 KNOTS. CURRENTLY FAY IS
EMBEDDED WITHIN A WEAK SOUTHERLY FLOW BETWEEN A MID-LEVEL TROUGH
AND THE SUBTROPICAL RIDGE. HOWEVER...THIS STEERING PATTERN IS
FORECAST TO CHANGE SOON AS A HIGH PRESSURE SYSTEM BEGINS TO DEVELOP
NORTH OF FAY. THIS NEW STEERING PATTERN WILL FORCE FAY TO MOVE
TOWARD THE WEST-NORTHWEST TOWARD THE COAST OF NORTH FLORIDA AND
GEORGIA. FOLLOWING CONTINUITY...THE OFFICIAL FORECAST SHOWS A
GRADUAL WEST-NORTHWEST TURN BUT GLOBAL MODELS FORECAST A SHARPER
WESTWARD TURN. IF SO...SOME SOUTHWARD ADJUSTMENT OF THE OFFICIAL
FORECAST COULD BE REQUIRED LATER ON.

THIS NEW DEVELOPMENT HAS PROMPTED THE ISSUANCE OF A HURRICANE WATCH
FOR A PORTION OF THE NORTH FLORIDA AND GEORGIA COAST.

QUOTE: Dr. Jeff Master has referred to Fay as "unprecedented"

The strengthening of tropical systems as they traverse South Florida does have recent precedence. TS Irene strengthed to Hurricane status while crossing from Naples/ Ft Meyers to Jupiter in 1998. Hurricane Wilma strengthed from a Cat 2 Hurricane to a Cat 3 Hurricane while crossing from Naples/ Ft Meyers to Jupiter in 2006. South Florida is very flat, with generally low growing trees and very swampy conditions. The water in the swamps is very warm in summer- can be 95 degrees or more due to the shallow dark bottom conditions. It is very easy to see why a tropical system would maintain or increase with the warm and moist environment!

Am I getting this right? The NHC says that Fay will become a hurricane somewhere right about where I live (in New Smyrna) after *strengthening* overland?!

It looks like the (now well formed) eye is going to pass right over our area and so we should brace for real hurricane force winds?

I'm just wondering what everyone else thinks. I was looking at the graphs and maps and tracks and it looks like theres a storm system over Texas and another near the Rockies dropping southward. What do yall think is the possibillity of Fay getting in the Gulf reintinsifying and coming toward Florida again. After going into the Atlantic and hitting us. Kind of concern, Also seen the short track of 94L does anyone think this is a concern for Florida.

So far a 3ft storm surge is predicted for the Florida Atlantic coast here:

Does anybody know what the expected rainfall from Fay will be in the Daytona Beach area?

thanks

Well, I enjoyed a brief lull in the weather here in Palm Bay. It's been constantly windy and heavy rain for about 5 hours. The bad weather has restarted and it seems to be raining ever harder than before.

Sorry that is incorrect:
http://www.srh.noaa.gov/mfl/events/?id=wilma
Wilma went from Cat 3 to Cat 2 as she crossed the state. I'm very familiar with this storm as it went right thru my backyard (literally!)

http://www.nhc.noaa.gov/1999irene.html
Irene simply maintained her Cat 1 status as she crossed, the pressured dropped, but only 1mb. Oddly I barely remember Irene at all.

Clearly a storm can strengthen over the Everglades & Lake O but I don't see any cases were it happened before on the scale we saw today. A 10mb pressure drop while over land for almost 12 hours is an extremely rare event (once in a hundred years maybe?)

Hurricane Isbell in 1964 is the closest comparison I've found. She maintained strength while crossing the Florida Peninsula, entering with winds of 125 and exiting with winds of 125.

She entered at 4pm at Everglades City and exited north of West Palm Beach at 9pm, so her time over land was very short.

Survived Charley at Cat 4 under a staircase. Won't do that again. I watch SW Florida and Abaco primarily.

It will spin on your latitude.

15 inches.


good luck.
