An ocean swell will continue to produce big waves and strong rip currents along the California coastline, forecasters warned Monday.
Waves will reach four to seven feet with occasional sets to nine feet along west- and northwest-facing beaches between San Luis Obispo County to San Diego County, according to the National Weather Service.
The largest waves probably will be near Ventura Harbor in Ventura County, as well as Manhattan Beach to Cabrillo Beach in L.A. County.
Weather forecasters say the swell also will produce sneaker waves in some of the coastal areas. The waves are capable of washing people into the sea from rocks, jetties and beaches, especially when the tide is high.
Forecasters are also warning swimmers and surfers of strong rip currents. A beach hazards notice for the coastline in Santa Barbara and San Luis Obispo counties remained in effect until 6 p.m.
The long swell was a welcome sign for organizers of the Mavericks Invitational surf contest at Half Moon Bay last week, where predictions of 40-foot waves appeared to have come true.
