A historic flash flood event occurred in Fort Lauderdale, Florida, and the surrounding areas on April 12, 2023.

The flooding rainfall in eastern Broward County, Florida, spanning from the midday hours of April 12 to roughly midnight on April 13, was supported by the combination of a weather front that was moving slowly through South Florida, and an intensifying area of low pressure in the Gulf of Mexico.

[9] The Weather Prediction Center (WPC) wrote in its Excessive Rainfall Discussion, that was issued on April 10, that, "...it anticipated that atmospheric conditions supportive of flash flooding in the Florida peninsula would persist into April 12, highlighting a "Marginal Risk" of flash flooding for urban areas along the coast of southeastern Florida...".

[13]The moist conditions persisted into the afternoon and evening, enabling the highly efficient production of rainfall in the storms as the warm front progressed north of Key Largo and into the Miami area.

[14] During the evening hours, stationary thunderstorms caused torrential rainfall over Fort Lauderdale, fueled by the locally moist atmosphere and a persistent inflow drawing moisture from the Atlantic towards the Florida coast.

[16] The cluster of storms began to weaken by around 11:00 p.m. EDT after dropping 10–20 in (250–510 mm) of rain in the Fort Lauderdale area.

The combination of wind shear, interaction between the warm front and the coast, and enhanced convection and vorticity resulting from the aggregation of thunderstorms may have produced conducive conditions for the development of tornadoes.

[35] Prior to the storm landing in Florida, many services such as American Red Cross opened shelters in area such as Holiday Park for those affected by the floods.

Additionally, the Florida Division of Emergency Management (FEDM) and Broward Sheriff's Office Fire Rescue Department deployed staff to the affected areas.

[38] Following the storm, Port Everglades, which handles 40% of Florida's gasoline distribution across 12 counties, announced that the flooding had disrupted operations.

By April 14, two days after the storm had passed, many gas stations in South Florida had run out of pre-storm supplies, and long lines had started to form at the few that remained open.

Customers reported wait times over 30 minutes and lines as long as 70 cars at stations nearly a week after the storm.
