Fay Hugging Fidel, Looking To Embrace Rays

You can track Fay via interactive radar as it approaches the US radar installations by clicking on this US interactive radar that can zoom to street level and loop.

Here’s the bottom line with Fay.  It’s going to hug the South Cuban Coast and make Fidel Castro’s less than desirable life even less desirable. At some point it will start

to turn and may eventually test out the meddle of the Tampa Bay Rays at Tropicana Field…as well as the roof. It’s moving around a ridge that is breaking down on the western edge due to a trof dropping down.  There also appears to be some ridging in the western Gulf making for a nice corridor for the storm to turn.  The question is when does it turn and where. The models are coming closer together with a run up the western side of Florida but a couple still want to take it up the middle or eastern side of the peninsula

while others are farther west,  though not as far west as previous runs.  Should the storm move a tad farther west and stay offshore, then it would be a stronger storm as it looks to have a pretty good structure.  Really, the only thing preventing Fay from becoming more formidable is running into land and remember the Domincan Republic and Cuba have some pretty sizable mountains.  So, as it stands, it has a brief chance to go toward a hurricane and the official track

takes it up to about 85 mph before moving into Florida around St. Petersburg and then moving into drought plagued Georgia.  The US Navy’s NOGAPS is

 perhaps the farthest west for the 12Z run and it takes it into Pensacola and then up into the Ohio Valley. That is the only way that Louisville will be affected and that is not overly probable at this juncture.  This will only become a major problem if it stays out over open water for a period of time, though it may surprise some folks with the forecast track as it wouldn’t surprise me to see it be one of those that starts to wind up quickly.  Certainly worth keeping an eye on  from Mobile to Miami.  The true track probably won’t show itself for another 24 hours or so, though I betcha it runs into the trof and scoots northeast across the SE US before going out to sea.   I have the spaghetti intensity graph and another spaghetti map on the right.   Here’s the discussion. 

TCDAT1
TROPICAL STORM FAY DISCUSSION NUMBER   5
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL062008
500 PM EDT SAT AUG 16 2008

REPORTS FROM AN AIR FORCE RESERVE HURRICANE HUNTER INDICATE THAT FAY
IS A LITTLE WEAKER THAN BELIEVED EARLIER…WITH THE INITIAL
INTENSITY NEAR 35 KT AND THE MINIMUM PRESSURE AT 1006 MB.  THE
SATELLITE APPEARANCE WAS RAGGED A FEW HOURS AGO…BUT A NEW CLUSTER
OF STRONG CONVECTION IS DEVELOPING IN THE SOUTHEASTERN QUADRANT.
THE CIRRUS OUTFLOW IS GOOD IN THE SOUTHEASTERN SEMICIRCLE AND FAIR
ELSEWHERE.

THE INITIAL MOTION IS 280/14.  FAY REMAINS ON THE SOUTH SIDE OF A
LOW/MID-LEVEL RIDGE…WITH THE LARGE-SCALE MODELS FORECASTING A
WEAKNESS IN THE RIDGE OVER THE EASTERN GULF OF MEXICO OR FLORIDA
THAT SHOULD ALLOW FAY TO TURN TOWARD THE NORTH-NORTHWEST OR NORTH
AFTER 36 HR.  THERE IS A LARGE SPREAD IN THE MODEL GUIDANCE ON WHEN
AND HOW SHARPLY FAY WILL TURN.  THE ECMWF AND NAM MODELS REMAIN ON
THE EASTERN SIDE OF THE GUIDANCE ENVELOPE…AND HAVE BEEN JOINED BY
THE GFDL WHICH HAS SHIFTED EASTWARD SINCE THE PREVIOUS RUN.  THESE
MODELS CALL FOR A SOUTHEASTERN FLORIDA LANDFALL.  THE GFS…HWRF…
GFDN…FLORIDA STATE SUPERENSEMBLE…AND THE CONSENSUS MODELS
FORECAST FAY TO CROSS WEST CENTRAL CUBA AND MOVE NEAR OR OVER THE
WEST COAST OF THE FLORIDA PENINSULA.  THE UKMET AND NOGAPS HAVE
BOTH SHIFTED EAST OF THEIR PREVIOUS RUNS…BUT ARE STILL ON THE
WEST SIDE OF THE GUIDANCE ENVELOPE IN CALLING FOR A MOTION TOWARD
THE FLORIDA PANHANDLE.  OVERALL…THE GUIDANCE ENVELOPE AND THE
MODEL CONSENSUS HAS CHANGED LITTLE SINCE THE LAST ADVISORY.  THE
NEW FORECAST TRACK IS A LITTLE FASTER THAN THE PREVIOUS TRACK AND
IS SHIFTED A LITTLE TO THE EAST AFTER THE 48 HR POINT.  EVERYONE IN
THE FLORIDA PENINSULA SHOULD MONITOR THE PROGRESS OF FAY…AS MOST
LOCATIONS THERE HAVE ABOUT THE SAME CHANCES OF EXPERIENCING
HURRICANE-FORCE WINDS ACCORDING TO THE NHC WIND SPEED PROBABILITY
PRODUCT.

WHEN FAY IS OVER WATER…IT APPEARS THAT ATMOSPHERIC CONDITIONS WILL
BE FAVORABLE FOR STRENGTHENING THROUGH 72 HR.  THUS…THE INTENSITY
WILL BE CONTROLLED BY LAND INTERACTION AND THE RESULTING IMPACTS ON
THE STORM STRUCTURE.  ALL GUIDANCE CONTINUES TO FORECAST
STRENGTHENING…AND THE INTENSITY FORECAST FOLLOWS SUIT IN BEST
AGREEMENT WITH THE SHIPS MODEL.  HOWEVER…THIS IS A LOW CONFIDENCE
INTENSITY FORECAST.  FAY COULD STRENGTHEN RAPIDLY IF IT BECOMES
WELL ORGANIZED OVER WATER…SUCH AS WHILE PASSING SOUTH OF CUBA OR
OVER THE STRAITS OF FLORIDA.  ON THE OTHER HAND…IT MIGHT NOT
STRENGTHEN MUCH AT ALL IF LAND INTERACTION PREVENTS ORGANIZATION.
THE INTENSITY FORECAST CALLS FOR FAY TO WEAKEN OVER THE UNITED
STATES AFTER LANDFALL.  SHOULD IT REMAIN OVER WATER AFTER 72
HR…THE LARGE-SCALE MODELS FORECAST INCREASING WESTERLY VERTICAL
SHEAR OVER THE SYSTEM.
