Swimmer Diana Nyad stayed on track Monday after a night of storms and jellyfish stings that set her back six hours when "all hell broke loose," her crew reported online.
Nyad, who turns 63 on Wednesday, is making her fourth attempt to swim the 103 miles of ocean between Havana, Cuba, and Key West without a shark cage.
Surrounded by a team of handlers in a boat, Nyad was in the middle of the Florida Straits by 3 p.m. Monday at the start of her 48th hour.
"Seas are pretty calm...single digit winds out of the south east," blogged Capt. Brandon Beach on Nyad's website. "Skies are clear."
The team estimated it will take at least 60 hours for Nyad to complete the swim, making her arrival in Key West likely sometime today.
Having trained for three years, Nyad first tried this marathon swim in 1978. She made two thwarted attempts last year and this time is wearing a full-body suit to help ward off jellyfish.
