A broad area of low pressure over the western Caribbean is being watched closely by the National Hurricane Center. Referenced by forecast models as Invest 93L, the disturbance has a medium chance of developing into a tropical cyclone by Saturday.
I explained in detail why this system may not become officially “named” before it arrives in a Facebook Like Wednesday night (about 2 minutes in)...
Showers and thunderstorms are likely to move into portions of South Florida as early as Saturday morning. Regardless if the system develops, there will be heavy rain and breezy winds on Saturday that quickly spread up into east-central Florida by Saturday night. Rainfall amounts of two to four inches are possible in a few spots, in particular from The Keys to South Miami-Dade County. One to three inches of rain are possible generally near and south of a line from Naples to Fort Pierce.
Inland waterways and lakes will be choppy with seas up to 5 feet, and offshore waters on the Atlantic Coast could grow to 8 feet. Winds might occasionally gust to 30 mph in the heavier rain bands, and sustained winds of 20 to 30 mph are possible immediately along the coast.
Conditions will rapidly improve across Florida on Sunday, thanks to a fast-moving cold front that will usher in drier, more stable air. This same front will team up with the departing system to become a powerful Nor’Easter riding up the Atlantic Coast. Nearshore winds up to hurricane force are possible from New Jersey to Maine Sunday and Monday, with heavy rain and mountain snow spreading well inland from the Mid-Atlantic States to New England. This storm has the potential to disrupt travel at many of our nation’s busiest airports Sunday and Monday, and travelers are being advised to check ahead with their air carriers before heading to the airport on those days.
