A tropical wave will make its way across South Florida Thursday, putting most of the region under a flood watch due to thunderstorms and heavy rain. But the wave will also cool the region slightly, a break for residents used to an endless string of heat advisories and “feels-like” temperatures reaching 110 degrees.
The National Weather Service has issued a flood watch for coastal and metro Broward and Palm Beach counties, and all of Miami-Dade, until 8 p.m. Thursday.
The wave “will keep deep tropical moisture over the region,” forecasters wrote in their Thursday morning advisory, which “will allow for potentially heavy rainfall, especially in the morning hours,” leading them to issue a flood watch.
Forecasters are predicting up to 2 to 3 inches throughout the day.
The good news is that temperatures will cool off slightly Thursday and Friday due to the cloud cover and storms, reaching only the mid to high 80s, with “feels-like” temperatures in the upper 90s and lower 100s, not enough for a heat advisory, the weather service said.
The respite will continue Friday with more rounds of showers and thunderstorms, keeping temperatures “near normal,” forecasters wrote. Highs will be in the upper 80s and low 90s.
“Heat indices will be slightly warmer than the break we have today,” forecasters wrote, “but confidence is low at the moment whether we will be back in heat advisory conditions.”
