Miami, Fla. – South Florida commuters could face stormy roads and flash-flooding risks Tuesday through Thursday as thunderstorms settle across the region. Morning traffic along I-95 and U.S. 1 may slow as heavy rain reduces visibility and pools on major routes.
According to the National Weather Service in Miami, scattered thunderstorms will build each afternoon through Thursday, September 25, bringing frequent lightning, gusty winds, and brief downpours. Heat index values could climb near 101 before storms develop, creating added risks for outdoor workers and afternoon events.
Miami-Dade, Broward, and Palm Beach counties should expect strong cells mainly after 2 p.m. each day, with rainfall totals ranging from a quarter-inch to localized higher amounts. Drivers should avoid flooded intersections, reduce speed during heavy rain, and allow extra time on evening commutes.
By Thursday night, storms may ease slightly, though lingering showers could still disrupt evening travel. Winds will shift north, offering a brief break before another round of unsettled conditions enters the weekend. Despite repeated showers, temperatures remain steady with highs near 88 to 89 and lows around 79.
The start of fall in South Florida feels more like a summer holdover, with humidity and daily storms locked in place. No significant cooling is expected until early October. Residents should monitor updates for any flash flood advisories or extended alerts.
