WHITTIER – A cold Pacific storm dropped buckets of rain and triggered lightning flashes across the Whittier area Friday as forecasters predicted a mostly damp weekend. There were no reports of serious damage or injuries from the storm, which also triggered a storm advisory for flood-prone areas and a snow advisory for the mountains of Los Angeles and Ventura counties. However, Los Angeles County Fire Department officials responded to a distress call at about 3:20 p.m. when a man on a raft fell into a river channel behind the golf course at the Whittier Narrows Recreation Area. The rafter managed to pull himself out, supervising dispatcher Ed Pickett said. “By the time we got there, was already out. He wanted us to rescue his boat,” he said, adding that firefighters fished out the raft. The storm dropped slightly less than a half-inch of rain in La Habra and slightly more than a half-inch in the Whittier Hills, the National Weather Service said. Between 6 and 10 inches of snow fell at 5,000 feet and above in the local mountains, the weather service said. The rain should begin tapering off by this morning, leaving partly cloudy skies this afternoon, with temperatures in the mid-60s. Overnight lows tonight will dip into the mid-50s, the weather service said. Clouds could begin building again by Sunday, however, when there is a 30 percent chance for more rain, forecasters said. Due to the rainfall, the Los Angeles County Department of Public Health advised beachgoers to stay out of the ocean, especially near discharging storm drains, creeks and rivers for at least 72 hours. Runoff areas may contain high levels of bacteria and should be avoided. Elevated bacteria levels in ocean water may cause some individuals to become ill. A Flash Flood Watch expired at 9 p.m. Friday for areas previously denuded by fire on Catalina Island, the mountains of Los Angeles County and the San Gabriel Valley. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
