Floodwaters swamped much of South Florida Saturday after nearly a foot of rain drenched the region.

Major flooding was reported in Miami, Palm Beach and Fort Lauderdale, among other cities as the waters began to rise shortly after midnight, according to NBC-2 Miami.

Images of cars driving through a foot or more of water, defying warnings from emergency services, and waist-high water filled social media.

While there were no reported deaths in Florida, at least two people in Cuba died during flooding on the island, about 90 miles south of Key West at the Sunshine State’s southern tip.

More than 400 flights were delayed or canceled because of the storm Friday and Saturday at Miami International, Palm Beach International and Fort Lauderdale-Hollywood International Airport, according to flight tracking site FlightAware.

Several videos of Phil Demers paddling a kayak through the flood waters in Downtown Miami also circulated online.

“We had the time of our life last night,” said Demers, an activist from Niagara Falls, Canada, who is in Miami to host a protest Sunday at the Miami Aquarium.

Demers said the impromptu paddle happened after he and his companions had dinner, and attempted to walk across the street to their hotel, but confronted a heavy flow of water.

“We were just so saturated, to the bone,” he said. They were joking about how they needed a boat to cross the water and the realization that their friend had a kayak atop his truck.

They took the boat down and started making their way through the knee-deep water.

“I got up some pretty respectable speed,” said Demers, who classified himself as a “veteran” paddler. “It was my most fun time ever in a kayak.”

While he was having fun, the heavy rains and strong winds toppled trees throughout the region, leaving thousands without power early Saturday. By late evening, about 3,500 homes and businesses in the state were still in the dark, according to PowerOutageUS, which tracks outages throughout the country.

Flash flood warnings were lifted for parts of Palm Beach, Broward and Miami-Dade counties Saturday afternoon as the storm moved across the Florida Peninsula and out to sea.

The deluge came from the remnants of Hurricane Agatha, which hit the Pacific coast of Mexico Monday, then passed over the Yucatan Peninsula, leaving 11 dead and dozens missing before heading north through the Gulf of Mexico.

The storm strengthened as it headed out to sea toward the Bahamas Saturday afternoon, with sustained winds of about 45mph, strong enough to become a tropical storm. The National Hurricane Center said it was expected to get that designation Saturday night.

If that happens, Tropical Storm Alex would be a rare system that was the first named storm in both the Atlantic and Pacific.
