A strong winter storm will bring feet of snow to locations around northern California from Tuesday afternoon until Wednesday evening. The most concerning location is near Mt Shasta City as the wind direction will favor heavy precipitation in that location and parts of northern California. We’re also forecasting strong winds in the Shasta Valley, so exposed areas will likely see wind gusts up to 50 mph mix with the heavy snow fall. Because of the strong winds and heavy snow, travel could be difficult to impossible near Mt Shasta City Tuesday evening. Remember to slow down and prepare for increased travel time during periods of heavy snow. You can call 511 for Oregon road conditions and for California road conditions call 800-427-ROAD (7623)

A cold front will bring snow down to some of the valley floors west of the Cascades Sunday through Monday morning. Look for snow levels mostly 1500-2500 feet, but falling lower late Sunday night into Monday morning in showers. 2 to 3 inches of snow is expected over the lower I-5 passes. The snow totals over the Cascades won’t be that much higher and will average around 4 inches. The Siskiyous are likely to see 3 to 8 inches Sunday into Sunday night. Be prepared for wintry travel above 1500 feet, carry chains in case you need them and/or they are required, expect increased travel time, and slow down.
