LOS ANGELES (AP) — Authorities are warning of dangerous rip currents at beaches along the coastline of Southern and Central California.

The National Weather Service said Monday that the unusually strong currents and high surf swell make ocean activities potentially hazardous from San Luis Obispo County to Orange County.

Surf is expected to create waves of two to four feet and breakers topping five feet.

The areas posing the highest risk are stretches from Point Mugu just south of Oxnard to Point Dume in Malibu, and from Long Beach south to Seal Beach.
