IMPERIAL BEACH, Calif. (KGTV)--A shark advisory is in effect Thursday after a juvenile great white shark was spotted at Silver Strand State Beach.
Two adult surfers spotted the 8-foot-long shark about 40-feet away from them at 8:15 a.m. near Tower 4 slowly traveling northbound.
Richard Dennison with California State Parks said the species "is predatory toward humans and may be a threat," so the advisory is in effect within a one-mile radius for the next 24 hours from the time of the incident.
One woman tells 10News she thinks she saw the shark and tried convincing her kids not to go in the water.
"It looked like the tail was sticking out and it would disappear and we were all like, 'no way!' and we saw it three times," said Ana Montoya.
Other lifeguard agencies were notified including Coronado, Imperial Beach, Navy base north of Silver Strand and the city of San Diego.
