Azores storm 92L unlikely to develop; East Pacific hurricane season begins
The hybrid low pressure system with both tropical and extratropical characteristics that formed Saturday over the far Eastern Atlantic, about 450 miles southwest of the southern Azores Islands (Invest 92L), has weakened considerably, and is unlikely to become Subtropical Storm Alberto. Wind shear has increased to a very high 25 - 40 knots over 92L today, causing a marked deterioration of the heavy thunderstorm activity. Also not helping is the fact 92L is over cold ocean waters of 68°F (20°C.) This is well below the 26°C usually needed for a tropical storm to form. Satellite estimates of 92L's winds were 35 mph at 7:45 am EDT Monday, according to NOAA/NESDIS. NHC estimated that 92L had top winds of 40 mph at 8 am EDT Monday, down 10 mph from Saturday's peak. Wind shear is expected to remain very high and water temperatures will cool as 92L moves northeast towards the Azores Islands on Tuesday and Wednesday, and the chances of the storm developing into a subtropical or tropical cyclone are near zero percent.

Eastern Pacific hurricane season begins
The first tropical depression of the 2012 hurricane season has formed this morning in the Eastern Pacific, and it comes one day before the official May 15 start of the Eastern Pacific hurricane season. Tropical Depression One-E is located about 645 mi south of Manzanillo Mexico, and is headed west, away from any land areas. Wind shear is a low 5 - 10 knots, ocean temperatures are a warm 29°C, and TD One-E has a good chance of becoming the season's first tropical storm by Tuesday. It is unusual to get a tropical storm forming this early in the year in the Eastern Pacific; since record keeping began in 1949, there have only been two that have formed by May 15--Hurricane Alma of 1990, and an unnamed 1996 storm. TD One-E will not live for long--the storm is headed towards a region with high wind shear and cooler waters that should be able to destroy it late this week.
Only weak potential for an Atlantic system developing over the next week
The models have backed off on their predictions of a potential subtropical storm developing over the Western Caribbean or waters near Florida this weekend, though it is possible we might see something develop along an old cold frontal boundary between the Bahamas and Bermuda. If such a storm did develop, it would likely move northeast out to sea.

SPECIAL TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
130 PM EDT MON MAY 14 2012
FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...
SHOWER ACTIVITY ASSOCIATED WITH A NON-TROPICAL LOW ABOUT
450 MILES SOUTH-SOUTHWEST OF THE SOUTHERN AZORES ISLANDS REMAINS
MINIMAL. ENVIRONMENTAL CONDITIONS ARE NOT CONDUCIVE FOR
DEVELOPMENT...AND THE SYSTEM HAS A LOW CHANCE...NEAR 0 PERCENT...OF
BECOMING A SUBTROPICAL OR TROPICAL CYCLONE DURING THE NEXT 48
HOURS. NO ADDITIONAL SPECIAL TROPICAL WEATHER OUTLOOKS ON THIS
SYSTEM ARE ANTICIPATED. ROUTINE ISSUANCE OF THE ATLANTIC TROPICAL
WEATHER OUTLOOK WILL BEGIN ON 1 JUNE 2012.
ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.

That's an active west coast seabreeze boundry.

This blog will be about our team's work, life in the arctic, climate change, and our inevitable adventures. Like last year, blog posts will be flown out of camp on stick drives whenever helicopters transport gear and people to and from our camp, and on every occasion someone is able to hike out to town (an all-day event that involves a river crossing).
??? 12Z GFS keeps the rains going especially for eastern FL.
CMC as well has trended wet this weekend as the low near Bermuda is dropped by the models.
From the NWS Wilmington, NC discussion about the potential development off the east coast
WHAT HAPPENS FOR THE WEEKEND IS STILL QUITE UP-IN-THE-AIR...AND
THERE IS A DISCONNECT BETWEEN THE GUIDANCE...AND EVEN AMONG
RUN-TO-RUN SOLUTIONS OF INDIVIDUAL MODELS. HOWEVER...WE CAN DEVELOP
SOME IDEAS ABOUT WHAT TO EXPECT. AS THE TROUGH KICKS FURTHER
OFFSHORE...IT DEEPENS OFF THE SE COAST AND WILL LIKELY CUT OFF DUE
TO RIDGING ACROSS THE NORTH ATLANTIC OCEAN. BENEATH THIS TROUGH...A
COLD CORE SURFACE LOW WILL DEVELOP...AND THEN TRANSITION TO WARM
CORE AS EVIDENCED BY AN INCREASE IN THICKNESSES IMMEDIATELY ABOVE
THE CLOSED CIRCULATION AND LACK OF A SIGNIFICANT OFFSHORE BAROCLINIC
GRADIENT. THE GUIDANCE HAS BEEN ALL OVER THE PLACE WITH SPATIAL AND
TEMPORAL POSITIONING...SO CANNOT HONE IN ON ANY SPECIFICS.
HOWEVER...WITH A DEEP TOUGH...AND MOST GUIDANCE SHOWING SOME
SEMBLANCE OF THIS FEATURE...THERE IS MODERATE CONFIDENCE IN
DEVELOPMENT. WILL CONTINUE SLIGHT CHANCE POP FOR SAT/SUN BUT NOTE
THAT IF CYCLONE DEVELOPMENT OCCURS FURTHER EAST...THE WEEKEND WILL
BE DRY.
That model is out to lunch.:) Moisture doesn't just build behind a frontal boundary unless there's a forcing mechanism to work with.
Most models have this boundary well south of us by early 12z Friday(around north-central Cuba). The GFS leaves it just south of Lake Okeechobee which seems suspect since a northern stream impulse will meet up with the southern streamer(over the Western Atlantic)-giving the front an extra boost.
The problem is there is no front that moves thru now that both the CMC and GFS have dropped the Mid Atlantic low. What happens front stalls and a moist east flow sets up.
I find it interesting that the GFS keeps on pushing this storm further and further out (based on forecasts from last week, it was supposed to start getting itself together on the 16th-17th, and then cross FL around the 21st)
lol, desperate measures on here for a storm. Sad thing is, Florida still aint gonna get rain, lol. If models were real world, there would be a surplus in Florida right now! lol
Wow... If that track actually happened, I would be in a whole world of trouble.
Yep...In the near term, I think this has the best shot in the Atlantic side.

Absolutely it is relevant. I was just giving you a hard time for posting an article from 2007.
Nice line forming here to my west. I would not be surprised to start seeing some warnings here over the next couple of hours.
last frame
just sayin.
I won't hold my breath. Tampa's shields are impenetrable.
Welcome EPAC Season... we've been waiting
A POSSIBLE tornado struck a small town a hour to southwest of me in Richmond County, NC at 12:50 pm EST. 3 houses is damaged. I think this is EF-0 or EF-1 twister. NWS Raleigh already sent people down there and they are working on it.

yeah I pulled this from one of the facebook sites on 5 State Weather of the tornado
Had a nice hook echo just 5 minutes ago.
