Diana Nyad's latest attempt to swim from Cuba to Key West ended early Tuesday when the 62-year-old endurance swimmer was pulled from the water.

Another storm slowed Nyad early in the morning as she entered the fourth day of her attempt to swim across the Straits of Florida.

According to the Nyad's blog, the swimmer and her team found themselves in the midst of the storm around 1:45 a.m. Tuesday. The blog post says everyone is safe but they were having to wait out the storm.

Nyad had been expected to arrive somewhere in the Florida Keys early Tuesday, but her team said she "lost six hours progress" in overnight storms Sunday.

Nyad was about 55 miles off the coast of Key West early Tuesday.

Nyad, who turns 63 on Wednesday, was making her third attempt since last summer to become the first person to swim from Cuba to Florida without a shark cage. She also made a failed try with a cage in 1978.

"She's doing well," a spokeswoman for the swimmer, Alex Crotin, said Monday afternoon.

After Sunday night's storm, Monday offered far more ideal conditions, with blue skies and level seas and the Gulf Stream offering beneficial currents.

Nyad's team said the swimmer's spirits were lifted Monday afternoon by a surprise visit from a boatload of friends and family. And Monday evening, she found herself swimming among dolphins, a far happier scenario than the sharks that were feared.

"The skies are clear, the sun high in the sky," crew member Brandon Beach wrote on Nyad's blog, calling it "a pretty gorgeous day out here in the middle of the ocean."

Still, the swimmer's crew was improvising ways to prevent hypothermia and to fend off further swelling of her lips and tongue. Though she's swimming in 85-degree waters, because that is lower than the body's core temperature, it will reduce her body temperature over time. Her team said she had been shivering.
