We will stay mostly dry for the first half of the weekend. Expect a lot of heat, humidity and sunshine on Saturday with isolated afternoon/evening storms over the inland areas.
Moisture from a tropical wave will be steered into South Florida starting Saturday night Sunday. This will lead to scattered showers and storms through Sunday evening. The primary threat will be street flooding concerns from anytime downpours. Strong storms also cannot be ruled out as well.
We will have a break in the abundant shower activity by Monday. Starting Tuesday night, an influx of deep tropical moisture is expected to move into South Florida, yet again. This will be associated with showers and storms from a disturbance over the Atlantic being eyed by the National Hurricane Center.
As of Saturday morning, an area of low pressure producing disorganized showers has a medium chance for development over the next 5 days. Strong winds in the upper levels of the atmosphere are making tropical development a challenge.
Regardless of tropical development, the showers and storms associated with it will bring us high storm chances starting Tuesday and Wednesday.
Additionally, the threat of a stormy setup will stick around for most of the week as lingering moisture and a front to the north trap deep tropical moisture over South Florida.
ALSO IN THE TROPICS
Tropical Storm Harvey continues to move west over the Caribbean Sea. No coastal watches or warnings are in place. Heavy rain will be the main impact this weekend, especially over the ABC Islands. Forecast cone suggest Harvey could be near hurricane strength by the beginning of next week. Those who live or are visiting the adjacent land areas of eastern Central America and northern South America should monitor the progress of Harvey.
There is also a tropical wave over the Eastern Atlantic with low chances of development over the next 5 days in the Central Atlantic.
