Another powerful storm from Alaska battered Southern California on Monday, dropping heavy snow that shut Interstate 5 near Gorman for more than a day and snarling traffic with rain that boosted the season's rainfall total in Los Angeles to almost four times normal.
By nightfall, the storm had dumped as much as 5 inches of rain on Southern California, and forecasters said that figure could double by tonight.
Waterspouts were sighted off the Palos Verdes Peninsula on Monday evening as the heart of the storm approached the coast, but there were no reports of damage. Hail frosted the ground in the Silver Lake district.
Flash-flood watches and winter storm warnings were issued throughout the Southland, as forecasters said the cold and rainy weather should linger through today, slackening only briefly before another storm front moves into California late this week.
"We're getting hit by a deep weather system off the coast that just doesn't want to go away," said Dan Keeton, a National Weather Service meteorologist. "It keeps pumping in cold air from the north and moist air from the south. When you mix those two, you get floods."
The storm total by 4 p.m. in downtown Los Angeles was 1.57 inches. It raised the total for the season, which runs from July 1 through June 30, to 15.47 inches. That's almost four times the normal season's total for the date of 3.96 inches. It's also more than L.A.'s average for a year, 14.7 inches.
But Keeton said it still wasn't enough to end the West's drought, which began seven years ago. "It provides some relief, but a drought is a multiyear problem," Keeton said. "One year of good rain doesn't mean a full recovery."
Other storm totals by 4 p.m. Monday included 5.39 inches at Refugio Pass in Santa Barbara County, 3.75 inches in Malibu, 2.24 in Ojai, 1.31 in Burbank, .95 in San Diego, .87 in Newport Beach and .66 in Riverside.
Monday's heavy snow delighted the operators of mountain ski resorts, but it caused the California Highway Patrol to close a 40-mile stretch of I-5 in the Tehachapi Mountains about 2:30 a.m. Monday. Officials expected to assess this morning whether to reopen the interstate.
The state's major north-south artery remained impassable throughout the day as California Department of Transportation crews struggled to clear up to 3 feet of snow from the road. Plows had removed most of the snow by nightfall, but ice on the pavement kept the highway closed.
