Miami, FL – Monday afternoon could bring the most active weather of the week to Miami as thunderstorms develop after 3 p.m., combining with tropical humidity to push heat index values to around 103°F. The National Weather Service warns of a 50 percent chance of storms, with the strongest cells capable of producing heavy rain and frequent lightning.
According to the National Weather Service in Miami, storms may be most intense during the late afternoon commute, especially along coastal and inland areas of Miami-Dade County. Southeast winds near 10 mph will add to the steamy conditions, making hydration and limiting outdoor exertion important.
Sunday also carries a storm risk, but Monday’s timing and heat make it the higher-impact day. Brief downpours could lead to ponding on roadways, and outdoor events may need to pause until storms pass. Travelers should allow extra time in the late afternoon and keep an eye on radar updates.
While storm chances continue into Tuesday, coverage should taper midweek, offering sunnier stretches and more manageable conditions. Additional advisories may be issued if storms intensify or become more widespread.
