Wind and Freeze Warnings in the San Fernando Valley Later Today LOS ANGELES (CNS) - A cold storm out of Canada will drop snow in the Antelope Valley and at low elevations in the San Gabriel Mountains today as wind and ice create horrendous travel conditions on some roads and a cold spell expected to last through New Years Day grips the region. The snow level is expected to start out at 4,000 feet today, followed by widespread snow showers in the afternoon, according to a National Weather Service statement. Winds are expected to gain in strength this afternoon. This evening, the snow level will drop rapidly to 2,000 feet by midnight, with between one and two inches of snow expected across the foothills north of Pearblossom Highway (state Route 138) and the Antelope Valley (14) Freeway, the statement said. The same amount of snow is expected on Interstate 5 through The Grapevine. The heaviest accumulation -- between two and four inches -- will be over the north-facing slopes of the eastern San Gabriels, with the snowfall tapering off Wednesday morning, setting the stage for a cold but dry New Years Day on Thursday. A dusting of snow is expected on the Antelope Valley floor, along with some isolated showers, forecasters said. A winter weather advisory -- replacing the more serious winter storm watch that had been promised Monday -- was expected to take effect tonight in the Antelope Valley, but forecasters said the bulk of the storms moisture will likely remain east of the area. A winter weather advisory is still scheduled to take effect at 3 p.m. and continue until 4 a.m. Wednesday for Los Angeles County mountains, excluding the Santa Monica range. Also expected today are strong winds -- 15-25 miles per hour with gusts of up to 45 mph in the Antelope Valley and of between 25 and 40 mph with 60-mph gusts in the San Gabriels, forecasters said. ``The combination of snow and wind will lead to very hazardous conditions for anyone venturing outside and onto mountain roads, warned the NWS statement. ``Roads will be icy, and road closures are a strong possibility, including at the 14, the 138 and Interstate 5 through The Grapevine. ``Be prepared for snow-covered roads and limited visibility, and use caution while driving, it said. Wind chill readings will fall to single digits in the mountains overnight, forecasters said. Little precipitation is expected outside the Antelope Valley and the San Gabriels, forecasters said. A tenth of an inch of rain could fall in valley areas outside the Antelope Valley, they said.
