Miami starts Saturday with clear skies and temperatures around 82 degrees, but the calm morning will give way to a hot, breezy and storm-prone afternoon. The high is expected to reach about 89 degrees, with the heat index climbing as high as 105.
Afternoon Storms Could Bring Heavy Downpours
Showers and thunderstorms have a 40% chance Saturday, with activity most likely building from late morning through the afternoon and early evening. South winds will be around 14 mph, with gusts reaching 22 mph, according to the National Weather Service Miami.
Most of the day will not be a washout, but any storm could bring a quick burst of heavy rain, lightning and sudden wind shifts. Localized flooding is possible where downpours repeatedly hit streets with poor drainage, especially farther north toward Palm Beach County and Lake Okeechobee.
Coastal Flooding Remains Possible Through Sunday
Minor coastal flooding remains possible across coastal South Florida through Sunday morning. It could put water on low-lying roads and property during high tide, so drivers should not attempt to cross flooded roadways.
Beach plans also come with a few extra conditions. Breezy onshore winds are expected to support a moderate rip-current risk along Atlantic beaches in Miami-Dade and Broward counties, while the risk is higher farther north toward Palm Beach County; swimmers should stay near lifeguards and leave the water when thunder is nearby.
Sunday Turns Drier Before A Sunny Midweek
Sunday should be mostly sunny with a high near 89 and a lower rain chance, though humidity will remain noticeable. Columbus Day on Monday will be sunny and slightly cooler, with a high near 88 and only a small chance of an afternoon shower or thunderstorm.
Tuesday and Wednesday look sunnier and drier, with highs around 87 and a gradual drop in humidity. Thunderstorms are possible Thursday, while Friday trends drier with only a 15% shower chance. The latest update extends the coastal flooding concern beyond the window outlined in Hoodline's Friday forecast.
