Miami, FL – Residents across South Florida are waking up to a heat advisory with feels-like temperatures soaring as high as 110 degrees through 7 p.m. Wednesday, as unrelenting humidity and dangerous afternoon sun grip the region. Health officials urge people to limit outdoor activity, check on neighbors, and stay hydrated, as heat illnesses become a growing risk by midday.
According to the National Weather Service in Miami, the advisory covers Miami-Dade, Broward, Palm Beach, and Collier counties from 11 a.m. until 7 p.m. Wednesday. Cities like Miami, West Palm Beach, Fort Lauderdale, and Naples will face some of the summer’s most oppressive heat, with light breezes providing little relief. East winds around 10 to 15 mph may bring scattered clouds and only a slight chance for a stray thunderstorm Wednesday afternoon, but the main hazard remains the heat.
Expect storms to increase late Wednesday night and Thursday, with daily rain chances rising to 80% by Thursday and Friday. Afternoon downpours could bring brief cooling, but humidity remains high and overnight lows stay warm in the lower 80s. Power usage may spike as residents rely on air conditioning—officials recommend drinking plenty of water, seeking shade, and avoiding strenuous activity outside.
The heat risk persists through Wednesday evening, but attention quickly turns to a stormier pattern for the rest of the week. Stay tuned for additional advisories if heat or storms intensify.
