Miami, Fla. – Dangerous heat will grip South Florida Friday before scattered to numerous thunderstorms develop during the afternoon and early evening, creating a dual threat of heat-related illness and strong storms across the region.
According to the National Weather Service in Miami, heat index values could climb to around 110 degrees across portions of the east coast metro Friday afternoon. A Major HeatRisk (Level 3 of 4) is forecast for Miami, Fort Lauderdale, West Palm Beach, Naples and Boca Raton, meaning the heat could affect anyone without adequate cooling or hydration.
As temperatures peak, showers and thunderstorms are expected to rapidly develop, especially across the interior and southeastern portions of South Florida. The highest rain chances arrive between 3 p.m. and 9 p.m., with communities including Miami, Fort Lauderdale, Homestead, Boca Raton, West Palm Beach and nearby areas facing the greatest potential for heavy downpours. Gusty winds, frequent lightning and localized flooding will be the primary hazards, with isolated small hail also possible.
Friday’s storms could create hazardous driving conditions during the evening commute as visibility drops in heavy rain and water collects on low-lying roads. Motorists should never drive through flooded streets and should expect brief travel delays where storms become strongest.
Residents are urged to drink plenty of water, wear lightweight clothing, limit strenuous outdoor activities during the hottest part of the afternoon and move indoors immediately when thunder is heard. The heat will ease somewhat over the weekend, but scattered afternoon thunderstorms are expected to remain part of the daily weather pattern across South Florida.
