Miami, Fla. – South Florida residents face stormy Labor Day plans as thunderstorms push into Miami by Monday afternoon, bringing heavy rain and lightning. Drivers on I-95 and U.S. 1 should prepare for sudden downpours, reduced visibility, and possible flooded lanes.
According to the National Weather Service in Miami, showers and thunderstorms will increase after 2 p.m. Monday, with rainfall amounts between a quarter and half an inch. Stronger cells could produce localized flooding, especially in low-lying neighborhoods and busy intersections. Evening storms are expected to linger past 8 p.m., complicating holiday travel.
Temperatures remain near 90 degrees, but humidity and heat indices could climb as high as 102 before storms arrive. The combination of heat and high moisture will make outdoor activities uncomfortable and potentially dangerous without proper precautions. Residents are urged to limit time outdoors during peak heat and stay alert to lightning threats at beaches and parks.
The unsettled pattern will not break quickly. Thunderstorms are likely each afternoon and evening through midweek, with the strongest chances Tuesday and Wednesday. Commuters should expect delays on major roadways during evening rush hours as scattered storms reduce travel safety.
By late week, slightly drier air may filter into South Florida, though daily storm chances will not fully disappear. Cooler air is unlikely to arrive until next weekend, keeping conditions hot and humid into September.
