From June 11 through June 14, 2024, heavy rainfall lead to flooding across South Florida caused by a trough of low pressure over the eastern Gulf of Mexico.

Meteorological history

On June 11, the National Hurricane Center (NHC) began monitoring a trough of low pressure over the Eastern Gulf of Mexico that was expected to produce heavy rainfall over the state of Florida.[3] Later that day, it was designated as Invest 90L, allowing for greater monitoring of the system.[4] [5] The invest then moved over Florida.[6] On June 13, the low pressure moved off the Eastern Florida coast.[7] By June 15, the system had merged with a frontal boundary.[8]

Preparations

Prior to the rainfall, Western Florida was experiencing a drought.[9]

Several counties had states-of-emergencies declared for them by Governor Ron DeSantis[10] along with Fort Lauderdale, Hollywood, and Miami-Dade County by their own leaders. The National Weather Service declared a flash flood emergency.[11] Fort Lauderdale and Miami Beach opened sites to distribute sandbags.[12] Over 100 pumps were set up on June 10.[13]

The northwest of The Bahamas was placed under flood watch from June 12 to June 14.[14]

On June 12, various places in Sarasota County, just south of Tampa Bay, recorded 24 hour rainfall totals of .[20] Rainfall of this magnitude can be expected to hit this area once every 500 to 1000 years.[21] Farther south, Fort Myers recorded of rain, the most recorded there in a 24 hour span.[22]

The South Florida Water Management District set up five temporary pumps in Miami Beach and along the Miami River.[23]

Interstate 95 southbound in Broward County had to be rerouted to avoid a flooded section of the route. Hundreds of flights were cancelled and delayed across South Florida. Flights were delayed on average seven hours according to the FAA. Half of the flights at Fort Lauderdale–Hollywood International Airport were delayed or cancelled. The Florida East Coast Railway, which is used by Brightline, in between Aventura and Miami was flooded.
