Expect a good chance of showers and storms by this afternoon, thanks in part to a tropical wave.
South Florida's Monday forecast calls for a mix of sun and clouds with highs in the mid 80s, lows in the low 70s and a 60 percent chance of rain.
The potential for heavy rains and street flooding should continue into Wednesday, the National Weather Service said.
Central Florida's forecast: Partly sunny with highs in the mid 90s, lows in the upper 70s and a 60 percent chance of showers and storms.
Other Bertha: From weather expert Jim Lushine:
Bertha will follow a parabolic path as it moves away from the Florida and remains only over the open waters of the Atlantic; a fish storm.
The path of this Bertha is similar to the last storm named Bertha, which emerged in July 2008. The 2008 Bertha brushed Bermuda as a tropical storm, but otherwise stayed clear of land.
Notably, it lasted 18 days and became the Atlantic's longest-lasting July tropical cyclone on record.
2008 Bertha was a major hurricane for a time and because of its slow motion, size, and intensity. It sent a series of high energy ocean waves crashing into the U.S. east coast even though it was more than 1,000 miles away.
This caused intense rip currents to form, which led to the rescue of 1,500 people in Ocean City, Md., and caused the deaths of three people along the Jersey Shore.
A similar situation occurred in 1990, when the Bertha of that year formed off the U.S. East Coast and created waves that caused hundreds of rip current rescues and two fatalities.
This year's Bertha will not be as strong or large as those other two but still will increase the risk of rip currents along much of the U.S. East Coast the remainder of the week.
