Miami, Fla. – Afternoon storms will bring lightning, heavy rain, and possible flooding to South Florida starting Thursday, while Miami faces a dangerous combination of heat and humidity through the weekend. Heat index values could reach as high as 106 degrees, making outdoor activity hazardous.
According to the National Weather Service in Miami, showers and thunderstorms are expected each afternoon through at least Sunday. The strongest activity will likely develop Friday afternoon into Friday night, when forecasters say storms are “likely” across Miami-Dade and Broward counties. Rainfall may cause temporary flooding on city streets, and lightning could lead to delays at Miami International Airport.
Highs will stay near 91 degrees daily, but humidity will push feels-like temperatures into the triple digits. Winds will shift from west to south, drawing in more moisture and fueling storm chances. Residents are urged to limit outdoor work during peak afternoon heat, drink water frequently, and stay indoors when thunder is heard.
Storm chances will decrease slightly by early next week, though isolated afternoon showers remain possible. Weather advisories may be extended if storm coverage increases.
