Miami International Airport was mostly cloudy at 77 degrees Friday morning, but the break is expected to be brief. Temperatures near 77 degrees and muggy air will give way to showers and thunderstorms, with a high around 87 and a 60% rain chance. Rain chances are expected to increase over the weekend.
Showers and storms could develop along the coast during the morning before becoming more numerous in the afternoon and early evening. Northeast winds will run around 14 mph, with gusts near 20 mph, while stronger storms could bring brief heavy rain, gusty winds and sudden changes to local travel conditions.
Afternoon Storms Could Flood Streets
According to the National Weather Service, some storms could produce rainfall rates of 1 to 3 inches per hour, with localized totals of 2 to 5 inches possible across South Florida. That combination could cause ponding and street flooding in urban and poorly drained areas, even if sunshine returns between downpours.
The current official outlook keeps rain chances elevated through at least the middle of next week. For comparison, readers can review Hoodline's earlier forecast; the National Weather Service forecast linked above is the basis for the timing and rain chances in this report.
What local flood planning emphasizes
The Miami-Dade County report cited here does not identify specific neighborhoods or transportation corridors, but it says localized tertiary drainage systems are the first local “line of defense” during rain events. The county also says those systems require active management to help reduce localized flooding, according to Miami-Dade County. For residents and travelers, that planning context underscores why intense downpours can produce uneven impacts across the county: local drainage conditions can determine where water ponds or streets flood, even when rain is intermittent.
Weekend Rain Chances Stay High
Saturday will bring another high near 87 degrees, with a 60% chance of showers and thunderstorms and more storms likely late in the day. Saturday night stays unsettled, with a low around 77 and a 70% rain chance.
Sunday is the wettest day in the near-term forecast, with a 90% chance of showers and thunderstorms and a high near 87. Monday keeps the same 90% rain chance, although both days could still see partly sunny breaks between storms.
Stormy Pattern Lingers Into Next Week
Tuesday through Thursday will remain warm, with highs near 88 degrees and rain chances around 80%. Overnight lows should stay in the upper 70s, while moisture continues to fuel daily showers and thunderstorms.
For drivers, the main concern is flooding in urban, low-lying and poorly drained areas during the heaviest downpours. Beachgoers should also note that a high rip current risk is posted for the Palm Beaches through 8 a.m. Friday, while conditions are expected to improve at area beaches over the weekend.
