Scattered showers and thunderstorms developed Wednesday, with the National Weather Service forecasting a 50% chance of showers and thunderstorms in Miami tonight, mainly between 1 and 2 a.m. The latest Miami forecast keeps a chance of storms overnight.
Wednesday’s daytime forecast called for a 60% chance of rain, with showers and thunderstorms most likely in the afternoon and evening. For tonight, the National Weather Service now forecasts a 50% chance of showers and thunderstorms, mainly between 1 and 2 a.m. The updated Miami forecast also calls for a low around 79 and says heavier rainfall is possible in thunderstorms.
South Florida’s flood risk comes from two sources this week: heavy rain and unusually high tides. The National Weather Service says a stalled front is helping keep deep moisture over the region, with repeated downpours raising the chance of localized flooding, especially in the east-coast metro. The City of Miami’s King Tide calendar lists Oct. 7–13 as a high-tide window; the city warns that these tides can flood low-lying streets even when it is not raining.
The forecast has shifted from Wednesday’s afternoon and evening storms to a 50% chance of showers and thunderstorms overnight, mainly between 1 and 2 a.m. The National Weather Service’s latest Miami forecast puts the low near 79.
Thursday Keeps The Wet Pattern Going
Thursday will remain hot, with a high near 88 and heat index values as high as 100. Showers and thunderstorms are possible before 2 p.m., with showers more likely around 2 to 3 p.m.; the chance of precipitation is 60%. The National Weather Service forecast also allows for heavier rainfall in thunderstorms.
Friday’s forecast now calls for a 40% chance of afternoon showers and thunderstorms, a high near 88 and heat index values as high as 100. Southeast winds of 11 to 14 mph could gust to 18 mph. Friday night, the rain chance rises to 70%, with southeast winds increasing after midnight. The latest Miami forecast includes those updated rain and wind details.
Wind And Coastal Flooding Risks Build Into Saturday
Rain chances increase Friday night and remain high Saturday: the National Weather Service forecasts a 70% chance of showers and thunderstorms Friday night and an 80% chance Saturday. Saturday is expected to be windy, with southeast winds of 18 to 22 mph and gusts up to 25 mph. The latest Miami forecast puts Saturday’s high near 88.
Minor coastal flooding may occur around high-tide cycles through the weekend as another round of King Tides arrives. Beachgoers should watch for changing conditions, and drivers should avoid flooded streets rather than testing whether a familiar roadway is secretly a swimming pool.
The coastal flooding alert is more specific than a general weekend outlook: the National Weather Service expects isolated minor flooding on low-lying roads and property along coastal Miami-Dade from Wednesday afternoon through Thursday morning, with high-tide cycles Wednesday evening and early Thursday. The agency advises drivers not to enter flooded roadways. The statement also covers coastal Broward and Palm Beach counties.
Late-Weekend Outlook
A drier pattern may develop late in the weekend and early the following week.
No watches, warnings or advisories are listed in the current forecast. Anyone planning outdoor activities Wednesday through Saturday should keep an indoor backup available, especially during the afternoon and evening when lightning and heavy downpours are most likely.
