The Accu-Weather forecast for Saturday, June 11, 2005, shows Tropical Storm Arlene will bring rain, thunderstorms and windy conditions to Florida and other portions of the Gulf Coast. At the same time, another storm system will bring rain and thunderstorms to the northern Plains and portions of the Midwest. A cold front will bring some showers to the northern Rocky Mountains.

TROPICAL STORM ARLENE DISCUSSION NUMBER 8
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 AM EDT FRI JUN 10 2005
Arlene has a ragged appearance in satellite imagery this morning...
with most of the associated convection in a poorly-defined band
northeast of the exposed low-level center.
An Air Force Reserve
Hurricane Hunter Aircraft found a broad and poorly-defined wind
center...A 1000 MB central pressure...and flight-level winds of 56 KT at 850 MB near the Isle of Youth.
How much of this wind is reaching the surface is questionable...as the convection in the area is somewhat isolated and the Isle of Youth reported 20 KT winds at 06Z.
However...these flight-level are strong enough to
justify increasing the initial intensity to
40 KT.
Arlene has turned to the left over the past 6 hr and the initial motion is now 340/7.
Water vapor imagery shows a large
mid/upper-level trough over the Gulf of Mexico...with a building ridge over the Western Atlantic and the Eastern United States.
This combination should steer Arlene generally North-Northwestward until it reaches the Northern Gulf Coast in 36-48 hr.
Dynamical models generally agree with this scenario...with some spread in both the track and speed.
The official forecast is down the middle of the
guidance envelope...calling for acceleration toward the
North-Northwest during the next 24 hr followed by some slowing as Arlene approaches the coast.
The new track is in best agreement with the UKMET and is shifted a little to the left of the previous forecast.
The intensity forecast remains problematic. On the strengthening side...large-scale models suggest the vertical shear should decrease somewhat during the next 24 hr as Arlene moves over the fairly warm waters of the loop current.
On the other hand...the broad wind structure and large amounts of dry air seen in water vapor imagery near Arlene both argue against strengthening.
The ships model calls for the storm to reach 45-50 KT intensity before landfall... while the GFDL calls for a 64 KT intensity at landfall.
The intensity forecast will compromise between the two models...calling for Arlene to reach 55 KT before landfall.
The forecast track and wind radii require a Tropical Storm Watch for the Northern Gulf Coast at this time.

Arlene has made the NNW turn...surf's up ping!
...Arlene emerging into the southeastern Gulf of Mexico...
a Tropical Storm Warning remains in effect for western Cuba from Pinar del Rio to the city of Havana and Havana provinces...including the Isle of Youth. These warnings may be discontinued later today.
A Tropical Storm Warning remains in effect for the Dry Tortugas.
A tropical storm watch remains in effect along the northern Gulf Coast from Morgan City Louisiana to Indian Pass Florida. A tropical storm watch means that tropical storm conditions are possible in the watch area during the next 36 hr.
Interests elsewhere in the northwestern Caribbean Sea and the eastern Gulf of Mexico should closely monitor the progress of this system.
For storm information specific to your area...including possible inland watches and warnings...please monitor products issued by your local weather office.
At 8 am EDT...1200z...the poorly-defined center of Tropical Storm Arlene was located near latitude 22.6 north...longitude 84.8 west...about 50 miles...80 km...north of the western tip of Cuba.
Arlene is now moving toward the north-northwest near 10 mph ...16 km/hr...and this general motion is expected to continue with an increase in forward speed during the next 24 hours. On this track...Arlene will be moving away from western Cuba this morning...and will be moving across the southeastern Gulf of Mexico today and tonight.
Reports from an Air Force Reserve hurricane hunter aircraft indicate that maximum sustained winds have increased to near 55 mph... 90 km/hr...with higher gusts. These winds are confined to a small area to the northeast of the center. Some additional strengthening is still possible during the next 24 hours.
Tropical storm force winds extend outward up to 140 miles ...220 km to the northeast of the center.
The latest minimum central pressure reported by the hurricane hunter is 1000 mb...29.53 inches.
Storm total rainfall amounts of 5 to 10 inches are possible during the next 24 hours across much of western and central Cuba...with isolated amounts up to 15 inches in the higher terrain of Cuba. General 3 to 5 inch amounts will be possible across the southern portion of the Florida Peninsula and the Florida Keys over the next 24 hours. Heavy rainfall associated with Arlene will likely begin to spread across the central and eastern Gulf Coast region later tonight.
Some coastal flooding is possible on the southern coast of western Cuba.
Isolated tornadoes may occur over portions of southwest Florida and the Florida Keys today.
Repeating the 8 am EDT position...22.6 N... 84.8 W. Movement toward...north-northwest near 10 mph. Maximum sustained winds... 55 mph. Minimum central pressure...1000 mb.
The next advisory will be issued by the National Hurricane Center at 11 am EDT.

OH NO MR BILL! (funny hurricane clip)
Come on, Arlene!
Is Arlene the one that was called Adrian in the Pacific and got a "sex change" when it crossed over Panama into the Caribbean? Or did Adrian cross over at below T-Storm strength and thus never got an Atlantic name?
Man we just can't catch a break in NW FL. Our beaches are still destroyed from Ivan the Terrible
Well, they better recover faster, hurricanes hit every year, like clockwork.
Arlene is a pop-corn fart.. In south Florida your average thunderstorm can produce winds in excess of 60 miles an hour..
I hope the boys at Gitmo make sure all Qurans are locked up safely so that they don't get ruined.
