Authorities in Florida warn of shark dangers on the Gulf Coast

SEACREST, Florida –

This weekend, authorities will be patrolling the ocean with boats and warning swimmers about sharks off Florida’s Gulf Coast, where three people were injured in two shark attacks on Friday.

Due to the attacks off the beaches of the Florida Panhandle, authorities temporarily closed several beaches to swimmers on Friday. The beaches reopened on Saturday with flags warning of the great danger.

In Walton County, the sheriff’s office, fire department and state conservation agency worked together to patrol the water with boats and the shore with vehicles, the South Walton Fire District said in an update Saturday. Both of Friday’s attacks occurred in Walton County.

“Please swim carefully today, respect the Gulf, drink plenty of fluids and take care of your loved ones,” the fire department said on social media.

On Saturday, red and purple flags were used to warn swimmers of the dangers.

“Purple flags indicate the presence of dangerous marine life and single red flags indicate a high danger level,” the Bay County Sheriff’s Office said in a social media post Saturday.

At this time of year, small fish are found in schools near the shore, which may have contributed to the attacks, the Bay County Sheriff’s Office said.

The first attack occurred Friday afternoon when a woman was bitten by a shark near WaterSound Beach, the Walton County Sheriff’s Office said. She suffered severe injuries to her abdomen and arm, and part of her arm had to be amputated, South Walton Fire Chief Ryan Crawford said at a news conference. She was flown to a trauma center.

Less than two hours later, firefighters responded to another beach about 4 miles east of the first attack “after receiving multiple reports of a teenager injured by a shark,” the sheriff’s office said.

Two teenagers were in waist-deep water with a group of friends when they were attacked, the South Walton Fire District said.

“When lifeguards and deputies arrived on scene, they found one of the women had significant injuries to her thigh and hand,” firefighters said in an update. She was flown to a trauma center. The other teen had what officials described as minor injuries to a foot.

“It is highly unusual for two of these incidents to occur on the same day,” Crawford said.

The timing of the attacks – mid-afternoon – was also unusual, said Walton County Sheriff Michael Adkinson, noting that sheriff’s officials often warn people to be on the lookout for sharks early in the morning and at dusk, which are typical feeding times.

Also on Friday, a woman was seriously injured in a suspected shark attack in the waters off the island of Oahu, Hawaii officials said.

According to experts, shark attacks are rare.

According to the University of Florida’s International Shark Attack File, there were 69 unprovoked bites worldwide last year, 10 of which were fatal. That’s more than the recent average of six deaths per year.
