Florida poised for a substantial soaking

An area of showers and thunderstorms is over the southeastern Bahamas and eastern Cuba, in association with a trough of low pressure. The latest 00Z and 06Z runs of the GFS, UKMET, NOGAPS, and ECMWF global dynamical computer models continue to forecast that this disturbance will develop into an extratropical low by Tuesday. The low should bring heavy rain and possible flooding problems to Florida and the Bahamas this week as it lifts northwestward over Florida. Up to nine inches of rain may fall over Florida by Friday (Figure 1), thanks also to a cold front expected to move over the state over the next two days. The exact timing and location of the rains over Florida are still uncertain, as the GFS model predicts development of the low over the Bahamas, while the ECMWF and UKMET models predict development over South Florida. At present, it appears wind shear will be too high to allow the extratropical storm to transition into a subtropical or tropical storm. However, if the storm's center emerges into the northern Gulf of Mexico late this week, wind shear may be low enough to allow a transition to a subtropical storm (10% chance).

Florida could use the rain--most of South Florida is under extreme drought, and Central Florida is under severe drought. The Lake Okeechobee water level is at 10.58 feet (Figure 2), which is about 3 feet below average. During the past week, the lake fell below the level that triggers water conservation measures for the first time since Tropical Storm Fay filled up the lake in August.

Figure 2. Water levels in Florida's Lake Okeechobee were under the level that triggers conservation measures between January 2007 - August 2008. Tropical Storm Fay then filled up the lake, which has gradually declined in level since, reaching water shortage management levels again in May 2009. Image credit: U.S. Army Corps of Engineers.

There has been little change to the large upper-level cold low spinning in the mid-Atlantic a few hundred miles east of Bermuda. The low may spin in place long enough over the next week to develop a warm core and be classified as a subtropical storm. It is unlikely that a subtropical storm forming that far out in the Atlantic this early in the year would pose a threat to any land areas, with the possible exception of Bermuda.

Climatology of early-season Atlantic tropical cyclones
Tropical storms are uncommon in the Atlantic before June 1, with only 26 named storms on record between 1851 - 2008. Five of these have made it to hurricane strength, and only one--Hurricane Able of 1951--made it to major hurricane status. Last year's Tropical Storm Arthur may be the deadliest May tropical cyclone on record. Though only a 40 mph tropical storm at landfall, Arthur killed five people in Belize and caused $78 million in damage. Three early-season storms have brought hurricane-force winds to land. The March 1908 hurricane swept through the northern Lesser Antilles Islands as a Category 1 or 2 hurricane, destroying at least 24 boats and causing damage to buildings on St. Bartholomew. Hurricane Able of 1951 brought sustained winds of 90 - 95 mph to the northern Bahama Islands, but caused little damage. Hurricane 2 of May 1908 hit North Carolina's Outer Banks as a Category 1 hurricane, but also caused little damage.

Good Morning All.......Very complex weather pattern around Florida this morning....My guess?...The dominant low is clearly (on the loops) deepening just off-shore of SW Florida, but, I'm not so sure about any significant development (other than a wind/gradient/rainmaker) given the proximity to land/almost over land right now and the significant dry air being sucked in on the West side....However, it does look like it is breaking off from the Trof so steering currents, and, shear levels if it can maintain over water at some point will determine the outcome....The moist Atlantic side may "save it" vs, the very dry/cool Gulf side which may prevent it from developing into anything tropical......JMHO

Just as I suspected...bye-bye 90L.

GOM low has a chance. Whether it's classified or not, doesn't really matter.

Excerpts from the 00Z Model Diagnostic Discussion

DEEP CYCLONE MOVING THROUGH THE EASTERN GULF OF MEXICO...

THE GFS/CANADIAN OUTRUN THE REMAINDER OF THE GUIDANCE WITH THIS SYSTEM AND LOOK UN-METEOROLOGICAL AS THEIR SURFACE LOW OUTPACES ITS UPPER LEVEL PORTION...MOVING WELL TO THE SOUTHWEST OF THE UPPER LEVEL PORTION OF THE CIRCULATION.

THERE IS A SMALL CHANCE IT COULD EVOLVE INTO A SUBTROPICAL CYCLONE AS 500 HPA/SEA SURFACE TEMPERATURE DIFFERENTIALS REACH MINIMAL CRITERIA FOR CONVECTIVE DEVELOPMENT IN THE SOUTHEAST GULF OF MEXICO /40C DIFFERENCE/ LATE TUESDAY. ALTHOUGH THIS IS CONSIDERED A LOW
PROBABILITY ALTERNATIVE SCENARIO AT THIS TIME...KEEP ABREAST OF THE SITUATION THROUGH THE LATEST TROPICAL WEATHER OUTLOOKS/DISCUSSIONS ISSUED BY TPC AND FORECASTS FROM OPC.

WEAK LOW MOVING FROM NORTHEAST OF CUBA/THE BAHAMAS INTO NORTHEAST FLORIDA LATE WEDNESDAY...

PER COORDINATION WITH TPC...WILL HAVE A SECOND SURFACE LOW MOVING UP THE BAHAMA CHAIN
INTO THE TREASURE COAST BY WEDNESDAY EVENING ACROSS THE FLORIDA PENINSULA BEFORE IT IS ABSORBED INTO THE LARGER SYSTEM IN THE SOUTHEAST GULF OF MEXICO. OCEAN TEMPERATURES APPEAR TO BE TOO COOL FOR TROPICAL CYCLONE DEVELOPMENT UPON THE FINAL LEG OF ITS JOURNEY
INTO THE SUNSHINE STATE FROM THE BAHAMAS...AND IT IS CURRENTLY EXPERIENCING VERTICAL WIND SHEAR.

Hmm, there appears to be an abnormally warm loop of warm surface water in the Gulf Stream south of Nova Scotia, located near 39N, 64W. Maximum water temperature is about 30C (86F). If a tropical storm passes over that while it's still intact, there could be some strengthening.

It is very interesting what is happening over Florida this morning, not to mention the approaching 90L.

Yesterday a low formed off the coast of Pinellas county and moved across the state out over the Atl off the coast of Melbourne around midnight last night. Now this morning the same low is back over central Florida (just south of Orlando and mostly in Polk Co) and is moving WSW back towards the central W Fl Coast. You can see this clearly on radar, and it's what's providing the West side of the state with the northerly breeze, and the east side with the southerly breeze... and all the moisture. I imagine that as this area of low pressure continues to slide westward that it will pull 90L up to the NW as well. Hopefully that low south of Orlando will be able to stay together as it heads back towards Tampa and develops heavier rain from afternoon heating.


the axsis of the ull is just north of key west area and is now finally starting to stregthen as it drifts ENE and then retro-grades back west possibly gaining some tropical charicteristics and a warm core,IMO....now would be the most likely time period for 90l to intensify as ULL conditions are more favorable then ever!!!!..today and tomorrow will be extremely wet over the Fl peninsula...

Off of the west coast of Florida. I imagine they'll relocate 90L there or designate it 91L.
