Florida's Fort Lauderdale experienced the rainiest day in its history Wednesday (local time) - a 1-in-1000-year rainfall event - sparking a flash flood emergency in Broward County that has prompted emergency rescues, forced drivers to abandon cars, shuttered schools and shut down the airport through 5am Friday. And more rain is on the way.
The region recorded widespread rainfall totals of more than a foot, while Fort Lauderdale tallied 25.91 inches (658mm) in a 24-hour period, according to preliminary reports from the National Weather Service office in Miami.
Two weak tornadoes also hit Broward County Wednesday, one just west of Hollywood and another south of the Fort Lauderdale airport, according to the Miami National Weather Service. Both were short-lived and rated EF-0, the weakest category.
While the rain Thursday won't reach nearly the amounts that fell on Wednesday, it will be problematic and create additional flooding, the National Weather Service said. Gusty winds, small hail and even isolated tornadoes are possible.
A flood warning for Broward County is in effect until 7:30pm, the National Weather Service said, and a severe thunderstorm warning is in effect for parts of Broward and Miami-Dade counties. The storms may bring winds of up to 60mph (97km/h) and potentially small hail.
Thunderstorms are beginning to develop across southeastern Florida and will once again bring a risk of flash flooding to the region.
"Isolated instances of flash flooding are likely this afternoon with locally heavy rainfall capable of 1-3 inch per hour rates," according to the Weather Prediction Center.
"This may lead to additional localised rainfall totals of 3-5+ inches, which could possibly aggravate ongoing flooding conditions across the highly sensitive Fort Lauderdale region."
While conditions are similar to Wednesday, favouring heavy rainfall, the prediction centre stated that there are significant differences from yesterday that should limit the prolonged occurrence of very heavy rainfall rates.
Between 14 and 20 inches of rain have drenched the greater Fort Lauderdale metro area since Wednesday afternoon, according to a Thursday morning update from the National Weather Service office in Miami. The deluge is the "most severe flooding that I've ever seen," one mayor said.
"This amount of rain in a 24-hour period is incredibly rare for South Florida," said meteorologist Ana Torres-Vazquez from the weather service's Miami forecast office.
Rainfall of 20 to 25 inches is similar to what the area can receive with a high-end hurricane over more than a day, Torres-Vazquez explained. She described the rainfall as a "1-in-1000 year event, or greater," meaning it's an event so intense, the chance of it happening in any given year is just 0.1 percent.
During the peak of Wednesday's deluge, a month's worth of rain fell in just one hour. Fort Lauderdale's average rainfall for April is 3 inches and it's been nearly 25 years since the city totaled 20 inches of rain in an entire month.
Extreme rainfall is a signature consequence of a warming climate, and it is happening more frequently. The deluge in South Florida is just the latest instance after 1-in-1000 year rains struck over the past year in areas including Dallas, St. Louis, eastern Kentucky and Yellowstone.
"Even though the heavy rain has concluded, numerous roads remain closed," the weather service said, adding that flooding is expected to persist.
Earlier, Fort Lauderdale was "experiencing severe flooding in multiple areas of the city," Fort Lauderdale Fire Rescue said on social media, warning to stay off the roads as vehicles may become stuck or submerged.
A flash flood emergency - the highest level of flood warning - that was in effect for portions of South Florida, including Fort Lauderdale, expired early Thursday.
City crews in Hollywood, Florida, "are doing everything they can" to deploy pumps wherever possible and keep drains clear, Mayor Josh Levy told CNN.
"We've recorded over 12 inches of rain since midnight, and that's on top of consecutive days of seemingly nonstop rain," Levy said. "The ground was already saturated so there is extensive flooding all over our city and throughout South Florida. Many roadways are impassable. Lots of vehicles got stuck and left abandoned in the middle of our roadways.
"I've lived here my whole life. This is the most severe flooding that I've ever seen," he said.
Several state agencies and emergency resources are assisting with the flood situation, according to a news release from Gov. Ron DeSantis.
More rain and storms expected
South Florida could get inundated with more even rain as showers and strong storms are in the forecast Thursday.
"After a historic day of rainfall across portions of South Florida that many of us will not soon forget, another potential wet day is ahead for today," the weather service in Miami said.
There is a slight risk, Level 2 of 5, for severe storms Thursday in parts of Florida, including Fort Lauderdale, Miami and Jacksonville, according to the Storm Prediction Center.
In Fort Lauderdale, airboats and high-clearance buggies have been secured from the county sheriff's office and the Florida Wildlife Commission as officials activated their emergency operations centre and will issue a proclamation of a local state of emergency, they said in a statement early Thursday.
Emergency crews worked continuously overnight responding to rescue calls across South Florida, Fort Lauderdale city officials said.
"City Hall remains closed. The ground floor is flooded, and staff is working to restore power to the building," said a Thursday morning update.
City officials are asking neighbours to be patient as "flooding conditions remain impactful in the southern areas of the City this morning," officials said.
"We expect the flooding to subside through the next hours and have seen improvements in certain areas of downtown."
Fort Lauderdale Fire Rescue crews received over 900 calls for service during overnight flooding, according to Fort Lauderdale Mayor Dean Trantalis.
The Broward Sheriff's Office assisted the agency in 300 rescue calls received during the historic flooding event, according to the mayor.
"There is not one area of this city that has not been impacted," Trantalis said.
Officials had asked residents to avoid driving or travelling in Fort Lauderdale amid the storms.
"Public Works staff are clearing drains and operating pumps to mitigate the water as quickly as possible. Efforts have been made to relieve traffic congestion through prioritised signalling to assist individuals leaving the City. We are requesting drivers to stay off the roads and avoid the City of Fort Lauderdale until the water has subsided," the city of Fort Lauderdale said in a news release on Wednesday evening.
"Because of the extreme amount of water, most areas will need to drain naturally," Trantalis said. "Crews are out in neighbourhoods clearing storm drains to aid water receding from neighbourhoods. Vacuum trucks are being deployed strategically throughout the city."
The Florida Highway Patrol has closed several exits on Interstate 95 in Fort Lauderdale, the city's fire department said.
In Coral Gables in Miami-Dade County, officials are working on two water main breaks, according to the Coral Gables Police Department.
Some roads in the city are shut down due to the flooding, while others have limited travel, police said, noting residents should give themselves extra time to commute to work.
The Broward Sheriff's Office said in a statement Wednesday it is "being inundated with non-emergency 911 calls regarding the inclement weather" and asks residents to use 911 only for "true emergencies," also telling residents to avoid driving and to call a tow truck company if a vehicle is stranded and not in an emergency.
Some local services are shuttering Thursday. The Fort Lauderdale-Hollywood International Airport is closed due to ongoing flooding in the vicinity and will reopen at noon, according to an update from the airport. The airport's departure level reopened to allow people to exit the area, the airport said early Thursday morning.
The Brightline train service has been temporarily suspended between Miami and Fort Lauderdale, the service said on social media.
Additionally, Broward County Public Schools announced the district will be closed Thursday.
"No city could have planned for this," Trantalis said.
Trantalis says he has spoken to the White House and Senator Marco Rubio about the situation.
The mayor said Gov. "DeSantis has not yet called but I'm sure he is very interested in what's going on here."
Trapped by floodwaters
Mandi-Lynn Guertin flew into Fort Lauderdale with her friends for a three-day country music festival that starts Friday.
The group flew in from Connecticut and had never experienced weather like this, Guertin told CNN.
The car they rented got stuck in about 3 feet of water, died and water quickly filled the inside, so they had to leave it on the side of the road.
"We currently can't leave our Airbnb because the flood waters are too high and no Ubers will come out to get us," Guertin said.
Guertin and her friends work in emergency services back home but Wednesday night, the quick nature of the flooding really scared them, she said.
"Southern hospitality and helping your 'neighbours' is truly a thing down here and I could not be more thankful today," she wrote on Facebook. "So many strangers did so much for us tonight."
For now, the group plans to wait it out at their Airbnb, without much of a choice and hope that enough water recedes so they can attend the music festival tomorrow, which has not been cancelled yet.
Rock The Ocean's Tortuga Music Festival, the oceanside festival, will "move forward" as planned, despite flood conditions in the city, according to event organisers.
Dawn Grayson lives 20 minutes from Fort Lauderdale - Hollywood International Airport and also got stuck on her way home Wednesday when torrential rain flooded the airport and surrounding roads.
Grayson was stuck in her car for several hours while she waited for flood waters to subside, she told CNN.
"The parking garages were flooding, and vehicles got stuck," Grayson said. "We were stuck in our vehicle for 5 hours on the terminal road."
