The leading edge of a cold storm arrived today in the Inland Empire, but it was just a taste of stronger rains likely in the afternoon and evening, according to a National Weather Service forecaster.
Heavier precipitation was expected later today, with total rainfall from the storm expected to range from 1 to 1-1/2 inches in the valleys, up to 2 inches in the foothills and 2 to 4 inches in the lower-elevation mountain areas, the forecaster said.
A winter-storm warning advised that heavy snow and strong winds were likely in the mountains above 4,000 feet where 6 to 12 inches of snow are expected.
More than 2 feet of snow was said possible on the highest peaks, with minor accumulations possible below the 3,000 foot level, the forecaster said.
He warned that residents and travelers in the higher elevations should be prepared for hazardous winter-weather conditions and possible road closures.
Travel may be impacted on Interstate 15 through the Cajon Pass late this afternoon through tonight and at times on Sunday into Monday, according to the National Weather Service.
By Sunday morning, the snow level could be down to 2,000 feet, the forecaster said
A wind advisory was in effect until 10 p.m. today, with southwest to west winds at 20 to 30 mph, with gusts of up to 65 mph possible. Gusty winds could make driving difficult, especially for motorists with high-profile vehicles.
Showers and possible thunderstorms were predicted for Sunday, with the chance of precipitation listed at 70 percent. The rain chance diminishes to 40 percent Sunday night and 30 percent on Monday, with conditions expected to begin drying out by Tuesday, with warmer, milder weather forecast.
