Beaches in Florida were largely empty ahead of Memorial Day as a slowly intensifying storm carrying brisk winds and heavy rain approached the U.S. Gulf Coast on Sunday.

The storm disrupted plans from Pensacola in the Panhandle to Miami Beach on Florida’s southeastern edge. Lifeguards posted red flags along the white sands of Pensacola Beach, where swimming and wading are banned due to high surf and dangerous conditions.

Subtropical Storm Alberto – the first named storm of the 2018 hurricane season – prompted Florida, Alabama and Mississippi to launch emergency preparations Saturday. Rough conditions were expected to roil the seas off the eastern and northern Gulf Coast region through Tuesday.

“These swells are likely to cause life-threatening surf and rip current conditions,” the National Hurricane Center in Miami said in a statement.

In Miami, organizers called off the sea portion of the Miami Beach Air & Sea Show Sunday because of heavy rain and rough waters. And in the Tampa Bay area on the central Gulf Coast, cities offered sandbags for homeowners worried about floods.

Gusty showers were to begin lashing parts of Florida on Sunday, and authorities were warning of the possibility of flash flooding.

The hurricane centre said Sunday that a tropical storm warning was in effect from Bonita Beach, Florida, to the Mississippi-Alabama border.

In Gulf Shores, Alabama, webcams showed beaches beginning to fill up as the storm’s track shifted slightly east away from the region, but red flags on the beach warned beachgoers to stay out of the rough water. Grant Brown, the city’s public information officer, said they had already finished a number of preparations such as clearing culverts to prepare for big rains but Sunday had turned into a “really nice day.”

With conditions expected to worsen overnight officials are encouraging people planning to check-out Monday to give themselves extra time.

Isolated tornadoes were possible across the region on Sunday and Monday.

Under overcast skies and occasional drizzle, several Gulfport, Mississippi, residents lined up to fill 10- and 20-pound (5- and 9-kilogram) bags with sand they will use to block any encroaching floodwater expected as a result of Alberto.

Tommy Whitlock said sandbagging has become a usual event in his life since he lives next to a creek.

“I’m doing this because every time we have a hard rain, it floods at my house,” Whitlock said. “We get water from other neighbourhoods, and water can get up to a foot deep in some places.”

Alberto – the first named storm of the 2018 hurricane season that officially starts June 1 – is expected to strengthen until it reaches the northern Gulf Coast, likely on Monday night.

The NWS said waves as high as 18 feet (5.5 metres) could pound the popular Gulf beaches in Baldwin County, Alabama, and northwestern Florida on Monday. A high surf warning was in effect through 7 p.m. Tuesday local time.

At 11 a.m. EDT Sunday, the National Hurricane Center in Miami said Alberto was about 130 miles (210 kilometres) west-southwest of Tampa, Florida, and moving north at 14 mph (22 kph). The storm had top sustained winds of 50 mph (80 kph).

A subtropical storm like Alberto has a less defined and cooler centre than a tropical storm, and its strongest winds are found farther from its centre. Subtropical storms can develop into tropical storms, which in turn can strengthen into hurricanes.

A tropical storm warning expired for Cuba’s western Pinar del Rio province, where heavy rains could trigger flash floods and mudslides, the National Hurricane Center said.

Tracey Gasper and her 6-year-old son, Chase, travelled to Biloxi Beach from Donaldsonville, Louisiana, for a day of fun in the sun with a group of friends from Baton Rouge, Louisiana. The weather had scared off the usual crowds expected for the holiday weekend.

“It was a 50-50 chance of whether to come down and we decided to chance it,” Gasper said.
