The remnants of Hurricane Rosa were expected to drop rain in the San Diego region Monday, a National Weather Service forecaster said. The storm already brought higher-than-normal surf levels to the coasts Saturday night. The waves were expected to peak Sunday night through Monday evening, before decreasing into Tuesday, according to the National Weather Service. Waves of three to five feet with sets to seven feet were predicted for San Diego County beaches, the NWS said. The swell direction was expected to give south-facing beaches the highest surf, such as Coronado and the Orange County coast.
