FORT LAUDERDALE, Fla. (CBS12) — Lifeguards in Florida had a busy weekend, rescuing more than 70 people from the ocean.

According to our news partners CBS Miami, many beachgoers were caught in dangerous rip currents, prompting authorities to issue warnings.

Visitors to Fort Lauderdale Beach felt the impact of these strong currents.

Zilah Rozadi, a beachgoer, described the experience: “It pushes you toward the middle of the ocean. You start over here and then in 30 seconds you’re on the other side. So it’s kind of dangerous.”

During the weekend, red flags were raised along the beach indicating hazardous conditions.

CBS Miami reported that on Saturday alone, lifeguards reported about 14 rescues. In each situation, swimmers found themselves in risky areas where seaweed on the ocean floor made the water dark and difficult to see.

Lifeguards explained that these areas have deep channels that allow water to flow back out to sea, creating powerful currents.

Unfortunately, the dangers were underscored by two drownings: a man in his 50s in Pompano Beach and a father who drowned while trying to save his children in Juno Beach.

Carrie Becharas, visiting from Michigan, noticed the yellow flags on lifeguard towers and took the time to speak with lifeguards about safety. “I had a lot of conversations with a lot of lifeguards,” Becharas said. “They explained where it was safe to go in and where it wasn’t safe.”

Lieutenant Mitchell Mccready of Fort Lauderdale Ocean Rescue emphasized the importance of safety: “We can’t stress it enough, don’t swim in an unguarded area. The ocean is not a playground for everybody, especially if you’re not watching currents or if you’re not acclimated to beach life.”
