A new shark sighting has prompted lifeguards to close the waters off Stinson Beach, about 20 miles northwest of San Francisco, rather than allow swimmers and surfers back into the waves as planned after a recent shark attack, officials said Wednesday.
A diver saw a shark about 100 yards offshore about 7 p.m. Tuesday, said Xavier Agnew, a lifeguard with the National Park Service. Though the beach and park remain open, swimming and surfing remain off-limits until Sunday.
