The weather for the rest of the week includes lots of thunderstorms, an 80% chance of rain most days, and the possibility of flooding, especially in urban areas that already received rain earlier in the week, said Robert Garcia, a meteorologist with the National Weather Service.
“The big thing we need to watch during the week is the potential for heavy rain and possibly even flooding, and strong wind gusts from thunderstorms that may develop,” Garcia said. He added that flooding could occur from Tuesday to Friday.
The National Weather Service expects hazardous marine conditions off Palm Beach and Broward counties on Friday, extending into Miami-Dade County waters on Saturday. These conditions include sustained winds of 20 to 33 knots and seas equal to or greater than 7 feet. These are hazardous conditions for small vehicles.
Winds from the offshore depression will combine with residual waves from Hurricane Lee to affect beach and ocean conditions.
The National Weather Service in Miami expects a high risk of rip currents in Palm Beach County through Wednesday evening, and a moderate risk in Broward County most of the week through Friday. Saturday will see high rip current risks from Palm Beach County south to Key Biscayne in Miami-Dade County.
The non-tropical low should move north toward Georgia and the Carolinas and “could gain some subtropical characteristics this weekend if it stays offshore,” according to the latest warnings. It has a 30% chance of developing in the next seven days.
“Regardless of subtropical development, this low could bring gusty winds, heavy rain and high surf conditions to parts of the coastal Carolinas to coastal mid-Atlantic states this weekend,” according to the latest warnings. “Gusty northerly winds are expected off the southeastern coast of the United States from Friday into Saturday,” the National Hurricane Center said.
