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. The rainfall broke several records across the region. Due to a possibility that the system could develop into a tropical cyclone, the National Hurricane Center designated it Invest 90L.

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.[11] The National Weather Service declared a flash flood emergency.[12] Fort Lauderdale and Miami Beach opened sites to distribute sandbags.[13] Over 100 pumps were set up on June 10.[14]

The northwest of The Bahamas was placed under flood watch from June 12 to June 14.[15]

Impacts

Multiple cities recorded over 15 in (380 mm) of rain from the system.[11][16] Fort Lauderdale received the average monthly amount of rain for June in 24 hours on June 12,[17] the wettest day in the city recorded in June.[18] Throughout the whole event, Fort Lauderdale received over 20 in (510 mm) of rain.[14] From June 12 to June 15, Big Cypress National Preserve received just under 28 in (710 mm) of rain.[19] Northeast Miami-Dade County received over 22 in (560 mm).[14] On June 12, various places in Sarasota County, just south of Tampa Bay, recorded 24 hour rainfall totals of 6–10 in (150–250 mm).[20] Rainfall of this magnitude can be expected to hit this area once every 500 to 1000 years.[21] Farther south, Fort Myers recorded 5.44 in (138 mm) 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.[11][21] Hundreds of flights were cancelled and delayed across South Florida. Flights were delayed on average seven hours according to the FAA.[12] Half of the flights at Fort Lauderdale–Hollywood International Airport were delayed or cancelled.[9] The Florida East Coast Railway, which is used by Brightline, in between Aventura and Miami was flooded.[12]

An EF1 tornado touched down at Hobe Sound in Martin County on June 12. Numerous trees along its path were toppled.[24]
