Until NHC actually starts issuing Outlooks on that, nothing except a blip on the tropical radar. The radar imagery does look a bit interesting, though.

[Mr. Rainman]

From NHC:

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

A NON-TROPICAL LOW PRESSURE SYSTEM INTERACTING WITH AN UPPER-LEVEL
TROUGH IS PRODUCING WIDESPREAD CLOUDINESS...SHOWERS...AND SCATTERED
THUNDERSTORMS ACROSS MUCH OF WESTERN AND CENTRAL CUBA...THE LOWER
FLORIDA KEYS...AND ADJACENT WATERS OF THE NORTHWESTERN CARIBBEAN
SEA...SOUTHEASTERN GULF OF MEXICO...AND THE FLORIDA STRAITS. THE
LOW IS CENTERED JUST WEST OF THE WESTERN TIP OF CUBA...AND A
SURFACE CIRCULATION CENTER IS GRADUALLY BECOMING BETTER DEFINED.
SHOWER ACTIVITY HAS BEEN SLOWLY INCREASING AND HAS BECOME BETTER
ORGANIZED TODAY...AND IF THIS DEVELOPMENT TREND CONTINUES...THEN A
SUBTROPICAL DEPRESSION OR A SUBTROPICAL STORM COULD FORM DURING THE
NEXT DAY OR SO BEFORE THE DISTURBANCE MERGES WITH A COLD FRONT.
THIS SYSTEM HAS A MEDIUM CHANCE...30 PERCENT...OF BECOMING A
SUBTROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES SLOWLY
NORTH-NORTHEASTWARD TONIGHT AND MONDAY MORNING...BEFORE TURNING
NORTHEASTWARD AT 10 TO 15 MPH TOWARD SOUTH FLORIDA AND THE FLORIDA
KEYS BY MONDAY AFTERNOON AND EVENING. REGARDLESS OF DEVELOPMENT...
THIS SYSTEM WILL LIKELY BRING LOCALLY HEAVY RAINFALL AND STRONG
GUSTY WINDS TO PORTIONS OF THE FLORIDA KEYS AND SOUTH FLORIDA OVER
THE NEXT COUPLE OF DAYS. ADDITIONAL INFORMATION ON THIS SYSTEM CAN
BE FOUND IN OFFSHORE WATERS FORECASTS ISSUED BY THE NATIONAL WEATHER
SERVICE...UNDER AWIPS HEADER MIAOFFNT3 AND WMO HEADER FZNT24
KNHC...AND ALSO IN PRODUCTS ISSUED BY YOUR LOCAL NATIONAL WEATHER
SERVICE FORECAST OFFICE. ADDITIONAL SPECIAL TROPICAL WEATHER
OUTLOOKS WILL BE ISSUED AS NEEDED.

If it becomes a subtropical storm, it will be named Alberto.

What's so funny about that? It's a La Niña winter for Pete's sake..

Only time there was something like this at this late (or perhaps early?) time was back in 93 with the superstorm.

Don't forget the Blizzard of 2006. Though it is still disputed whether or not it was a subtropical storm.

[TWCToday]

Lol. This is stupid that the NHC is even looking at this.

This situation may seem silly to consider at first, but you may not realize that at least one subtropical or tropical storm has formed in every month of the year over the Atlantic basin since 1851.  Only five have formed between January and April, so it's very rare to see one develop now.  This feature would have to develop really soon before it merges with a frontal boundary.
