Miami started Sunday clear and muggy, with temperatures around 81 degrees and another hot afternoon ahead. The high should reach 88 degrees, while the heat index could climb to 101, and east winds around 10 to 14 mph will keep the coast breezy.
Beachgoers should take extra care: dangerous rip currents remain a concern along the Atlantic beaches in coastal Miami-Dade, Broward and Palm Beach counties through Sunday evening. The National Weather Service in Miami advises swimmers to stay near a lifeguard, avoid fighting the current and move parallel to shore if pulled away from the beach.
Sunday’s Dry Outlook Shifts to Afternoon Storms
Miami has only a slight chance of a shower Sunday, with mostly sunny skies through the afternoon. Monday’s high should again reach 88 degrees; the chance of showers and thunderstorms rises to 30% to 40% after 2 p.m.
Rain chances increase Tuesday through Thursday. Showers and thunderstorms are likely after 2 p.m. Tuesday, with a 60% chance of rain, followed by an 80% chance Wednesday and 70% Thursday.
Warmth Persists as Rain Chances Rise
The wetter forecast is not expected to bring much temperature relief: afternoon highs should remain in the upper 80s, with heat index values generally in the upper 90s or low 100s. Overnight lows are forecast near 79 degrees Tuesday and Wednesday.
Rain chances also remain high Friday and Saturday. For additional local coverage of South Beach conditions, see Hoodline’s Saturday report.
Heavy Rain and Lightning Could Disrupt Plans
Storms later this week may bring frequent lightning, brief heavy downpours and localized flooding, especially where rain falls quickly over paved neighborhoods. Outdoor plans should have an indoor backup, and anyone who hears thunder should leave the beach or pool and wait for conditions to improve.
How the County Accounts for Runoff
According to Miami-Dade County Transportation and Public Works, the county’s Stormwater Utility bases fees partly on impervious surfaces, such as rooftops and parking lots, because they generate runoff the utility must handle. The county information cited here does not specify which physical drainage systems are used.
