South Florida is set for a challenging Sunday as dangerous heat combines with strong thunderstorms. Residents in Miami-Dade and Broward counties should be cautious, especially in the afternoon, when heavy rain could make driving along I-95 and U.S. 1 difficult.
Heat and Storms Arriving Together
According to the National Weather Service, storms are most likely after 2 p.m. on Sunday. Some places could see more than half an inch of rain, leading to localized flooding.
Before the storms arrive, heat index values could soar to 103°F, raising risks of heat exhaustion. With both high humidity and storm potential, people are advised to stay hydrated and avoid long hours outdoors.
Travel and Outdoor Hazards
Drivers should avoid low-lying roads during heavy rain as ponding water can make travel unsafe. Afternoon winds could gust up to 20 mph during storms, further affecting driving conditions. Beaches from Miami Beach to Key Biscayne also carry a higher rip current risk through Sunday night, making swimming unsafe.
Advisory for Residents
Residents are advised to:
Charge phones and devices in case of power outages.
Secure outdoor furniture and loose items ahead of storms.
Stay indoors during the heaviest rainfall to avoid flooding risks.
Localized power outages may occur with stronger storms, and more advisories could be issued if rainfall increases.
Outlook for the Week Ahead
While Monday will bring scattered storms, drier conditions are expected in the morning with renewed storm chances later in the day. Tuesday may start sunnier but could still see evening thunderstorms. Heat remains consistent all week, with highs near 90°F each day.
