According to the National Weather Service, heavy rainfall is possible. The chance of storms will be much lower on Monday and will be limited to the highlands and Antelope Valley. Further inland, a flood watch was also in effect until at least 11 p.m. Saturday for much of Riverside County and parts of San Diego County. A beach hazard statement was also issued until Wednesday afternoon for the Malibu coast and other Los Angeles County beaches, where dangerous rip currents and breaking waves were expected due to the 3- to 6-foot high swell. Swimmers and surfers were advised to stay out of the water due to hazardous swimming conditions or stay near occupied lifeguard towers. Rock jetties can be deadly in such conditions as well. Despite the chance of rain, weekend temperatures remained warm, staying in the 70s to mid-80s from the beaches to downtown Los Angeles, topping 90 degrees in many valleys and nearing 100 degrees in the Valley of Antelope. More typical midsummer weather is expected for the rest of the week, with overnight to morning cloud cover in coastal areas and temperatures within a few degrees of normal, forecasters said.
