Miami, Fla. – South Florida enters Sunday under a dual threat of dangerous heat and strong thunderstorms, raising safety concerns for residents and travelers. Afternoon storms could unleash heavy rainfall on Miami-Dade and Broward counties, making driving along I-95 and U.S. 1 hazardous by evening.
