Miami is starting Tuesday with early-morning temperatures near 78 degrees, but the quiet morning is expected to give way to a stormier day. Showers and thunderstorms are likely to develop by the morning, with heavy downpours possible through the afternoon and a high near 87 degrees.

Storms Could Arrive During The Morning

According to the National Weather Service in Miami, showers and thunderstorms are likely after approximately 11 a.m. to noon EDT, with rain chances around 70% Tuesday. South winds of about 6 to 12 mph will add moisture as storms move through.

Most areas could pick up roughly a half-inch to an inch of rain, but slow-moving or repeatedly developing storms may produce much higher totals in a short time. The main concern is localized flooding on urban streets and in poor-drainage areas, especially where several downpours track over the same neighborhood.

Wet Pattern Holds Through The Weekend

Tuesday night stays unsettled, with a low near 77 and a 50% chance of additional showers and thunderstorms. Wednesday looks even wetter, with a 90% rain chance and a high near 87, followed by more storm chances Thursday and Friday as highs remain in the upper 80s.

The latest forecast adds a sharper flooding concern to the broader wet pattern outlined in Monday's Hoodline outlook. Storm chances remain elevated into the weekend, with rain chances around 50% Monday.

Plan Around The Downpours

Morning commuters and anyone with outdoor plans should keep rain gear nearby and allow extra time for sudden visibility drops or water-covered streets. Lightning can accompany the stronger storms, so move indoors when thunder is audible and avoid driving through flooded roadways.
