Miami woke Wednesday to partly cloudy skies, muggy air and a stiff northeast breeze, with temperatures around 75°F at Miami International Airport shortly before sunrise. The bigger concern is along the coast: a Coastal Flood Warning remains in effect through 8 p.m., with low-lying roads and waterfront property at risk during high tide. The forecast otherwise trends mostly sunny and warm, but the water will be no place for casual plans.

Flooding Remains The Main Hazard

The National Weather Service Miami office says significant coastal flooding is expected across coastal Miami-Dade and Broward counties Wednesday, and some roads may close. A Coastal Flood Advisory takes over at 8 p.m. Wednesday and remains in effect through 8 p.m. Thursday, so moderate flooding may continue around later high tides even after the warning expires. Drivers should never go around barricades or drive through water of unknown depth, especially at night.

The latest update extends the coastal concern beyond the timing outlined in Tuesday's Hoodline coverage. Conditions should improve overall as winds ease, but the coast will remain vulnerable through Thursday.

Showers Fade As Sun Takes Over

Wednesday's high should reach about 85°F. There is a 30% chance of showers and thunderstorms, mainly before noon, followed by a smaller chance from roughly 1 to 5 p.m.; rainfall totals should stay below a tenth of an inch in most spots. Northeasterly winds around 12 mph will ease toward evening.

Warm Halloween Weekend, Wetter Sunday

Thursday and Friday look mostly sunny and near 85°F, though each day carries a slight chance of a shower or thunderstorm. Saturday's Halloween forecast stays warm around 85°F but brings a 50% rain chance and east winds gusting up to 21 mph. Sunday looks more unsettled, with a 60% chance of showers and thunderstorms and a high near 84°F.

Beachgoers And Boaters Should Wait It Out

A high risk of rip currents continues along Miami-Dade and Broward beaches through Wednesday evening. Marine conditions should remain rough into tonight, with small-craft-advisory conditions lingering for boaters; swimmers should stay near lifeguards, and anyone caught in a rip current should float and move parallel to shore rather than fight the current.
