Miami, Fla. – Thunderstorms could intensify across South Florida on Patriot Day, September 11, raising concerns for both travel and remembrance events. Heavy rain, lightning, and gusty winds may hit Miami during the afternoon and evening, with flash flooding possible on I-95 and local streets. Residents attending National Day of Remembrance ceremonies should prepare for sudden weather disruptions and consider carrying rain gear.
According to the National Weather Service in Miami, storms are most likely after 2 p.m. Thursday, with an 80% chance of rain by evening. Temperatures will reach near 89, though heat index values could push conditions into the low 100s before storms arrive. Southeast winds may shift north overnight, keeping humidity levels high.
Localized flooding remains the biggest threat. Poor drainage areas near downtown Miami and coastal neighborhoods could quickly accumulate standing water. Drivers should avoid underpasses and low-lying routes during heavy rainfall. Flight delays are possible at Miami International Airport if lightning persists.
Friday brings another round of storms, with showers developing by midday and lingering through the evening. Winds will shift northeast at 7 to 10 mph, bringing slightly cooler air by Saturday. Still, scattered afternoon storms remain in play for the weekend, limiting outdoor activities.
Stay weather-aware and plan ahead. Thunderstorm threats will continue into early next week, keeping Miami under an unsettled late-summer pattern.
