By Donna Thomas, SouthFloridaReporter.com Meteorologist, Sept. 29, 2015 – South Florida will see more late September storms on Tuesday, but changes are coming. Tuesday started with morning showers and storms in the Keys, and storms will build on the South Florida mainland, bringing periods of heavy rain from late morning into the early evening. Tidal flooding is likely again in low-lying coastal areas during the late morning and late evening on Tuesday. Tuesday’s highs will be around 90 degrees. Showers and storms are in the forecast again on Wednesday, along with highs around 90 degrees. October will begin with showers and storms on Thursday, and highs will be in the upper 80s. Look for drier air to work its way in beginning on Friday, but a few early showers and a stray afternoon storm aren’t out of the question. Friday’s highs will be in the upper 80s. A pleasant change comes this weekend, with significantly lower humidity, plenty of sun, and highs in the mid 80s — our first taste of autumn.
In the tropics, Tropical Depression #11 is now Tropical Storm Joaquin, with top winds of 40 miles per hour. At 5 am, Joaquin was located near 26.6 North, 70.6 West, and was moving west at 5 miles per hour. While the computer models are not in agreement on Joaquin’s strength and track beyond 2 or 3 days, the storm is forecast to turn northward east of the Bahamas and potentially threaten the U.S. east coast from the North Carolina Outer Banks northward. The low we’ve been watching in the Gulf is now off the Tampa coast and will bring plenty of rain to portions of the Southeast U.S., even if it has a low chance of developing into a depression. And an area of disturbed weather in the central Atlantic a few hundred miles northeast of the Leeward Islands has a low chance of developing over the next few days as it moves slowly west-northwestward.
