Re: Yucatan Channel feature

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.

Latest, 7 minutes old, DISTURBANCE INVEST (AL902012) 20120206 0000 UTC

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

SPECIAL TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
645 PM EST SUN FEB 5 2012

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.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.
