Miami Overnight Weather: Flood Watch Starts at 10 A.M. Sunday, With Thunderstorms Monday and Tuesday
It is 76 degrees and overcast in Miami overnight, with drizzle Sunday under a Flood Watch, an 78 percent thunderstorm chance Monday and more storms on Election Day.
Miami sits at 76.4 degrees under overcast skies in the overnight hours, feeling like 80.7, on the station's live Open-Meteo feed - the quiet edge of a wet three-day stretch. Sunday brings drizzle and a high of 82.9 with a 58 percent precipitation chance, and the National Weather Service in Miami has a Flood Watch in effect for all of Miami-Dade, Broward and Palm Beach counties from 10 a.m. Sunday through 3 p.m. Monday.
The watch is the headline. An upper-level low moving atop Florida will add moisture and support for showers and storms, the weather service says, and strong low-level easterly flow can set up bands of repeated heavy rain - the setup for urban and street flooding in spots that catch the same band twice. The same overnight issuances extended the beach alerts: a Rip Current Statement and a Coastal Flood Advisory for coastal Miami-Dade now run through Monday at 7 p.m., with minor to moderate coastal flooding expected - lots, parks and roads can flood around high tides, with only isolated road closures expected.
The pattern does not break after the watch. Monday carries a 78 percent chance of thunderstorms with a high of 79.6, and Election Day, Tuesday, stays stormy at a 74 percent chance and a high of 81.8 - worth knowing for anyone planning a Tuesday trip to an assigned precinct. Wednesday's shower chance falls to 29 percent, and the feed dries out toward the end of the week, with Saturday back to overcast and an 8 percent rain chance.
The practical overnight advice is the standing South Florida set: never drive through water of unknown depth, expect ponding on low streets during the heaviest bands Sunday and Monday, and treat the beaches as a look-but-do-not-swim proposition while the rip current statement runs. The Flood Watch means conditions are favorable and a warning could follow if heavy rain sets up over one area - the desk will update the file if the watch is upgraded.
