Interesting system centered in the Yucatan Channel today. Fair convection and what may be the beginnings of a LL circulation. It is detached from any frontal zones and over SST of 80 - 81ºF. It is unseasonably warm over Florida and the SE Gulf. Although there is some shear evident, it could, at a minimum, bring some rain into Florida as it tracks N - NE. In my opinion, the chances for development are rather low.

The weak low pressure system is located in the Yucatan Straits just off the western tip of Cuba. Windshear is rather low and SSTs are about 27C. System has spotty convection and could bring some much needed rain to south Florida. Movement should be to the northeast to east northeast and significant development is not likely as the system moves into cooler SSTs.

Added: South Florida Water Management District is calling this system Storm 90 as of 05/12Z (i.e., Invest 90).

I was surprised to see this developing on satellite yesterday. It sure has some of the visual cues that usually cause excitement during the 'regular season'. GOM water temps are incredibly warm for this time of year so there is plenty of energy and moisture. Seeing LOTS of storms near Key West that might be indicative of a mid-summer day. This warm winter has also been quite dry so some rain would be greatly appreciated!

Shame on Me. I had seen the 'visual cues' that you mentioned and totally discounted them due to the Calendar being Feb 4th.
Not to mention the transition back to night shift after 5 years of day shift.

The SHIP model has it's maximum wind speed at 31 kts at the 24 hour mark. This time tomorrow night.

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

This feature is really close to land. It's common to have subtropical system out over the Atlantic somewhere, but this close in to land makes you really sit up and pay attention.
It may be February but it has been extremely warm, the water is warm... an interesting year of mixed signals.
Alaska and Europe are freezing, parts of the country mild and South Florida feels more like April than February.

At 06/06Z, Invest 90 was located near 22.9N 83.3W on the northwest coast of Cuba moving east northeast at 10 knots. Convection is not well organized. Windshear over south Florida is expected to increase to 30 knots by Monday evening and more than twice that by Tuesday morning so chances for additional development should be decreasing but some pockets of heavy shower activity are possible over south Florida on Monday. Note that Key West received 4.3 inches of rain on Sunday.

The shear got to it today, so no development.
Had typical afternoon showers here today. That would be good if it were the first week of June.

MIchael, when I got home from work, the Tampa radar appeared like it would on a typical June/July afternoon with a solid band of Thunderstorms along a seabreeze boundary! That is more than crazy for early February! Of course, the rain missed my house, but poured at work!
