SAN DIEGO (CNS) - A series of storms over the Northern Pacific will generate increasingly large west-northwest swells along San Diego beaches this week, prompting meteorologists to issue a beach warning starting late Monday night.

The National Weather Service scheduled a beach hazards statement for local beaches from late Monday night to Saturday evening, saying 4- to 7-foot surf with sets to 9 feet is expected Tuesday afternoon, followed by 10-foot sets Wednesday through Thursday.

The largest surf will likely occur on Friday and Saturday when sets of 12 to 14 feet are possible, according to the Weather Service.

"The swells (will) start to very slowly lower late Saturday into Sunday," the agency said.

A beach hazards statement is issued whenever high surf capable of producing hazardous swimming and surf zone conditions is expected.

"The high surf and strong rip currents will result in dangerous swimming conditions," the NWS said. "Waves may over-top jetties and sea walls at times."
