National Weather Service Sacramento is forecasting heavy mountain snow in the northern Sierra region. Motorists conducting essential travel are being alerted to a series of storms which will bring impactful winter weather across Northern California this weekend. Essential mountain travel is expected to become difficult by afternoon and evening on Friday, December 25, and continue through early Saturday morning. A brief break is possible late Saturday night through Sunday morning before another weather system is expected late Sunday into Monday. If traveling in the mountains, carry chains, extra warm clothing and food, and be prepared for significant travel delays.
Travel conditions are expected to be difficult with the potential for heavy snow. Total snow accumulations of 12 to 18 inches are possible above 5,000 to 6,000 feet with localized amounts of up to 3 feet over peaks. There is a potential for lighter accumulations of snow, between 3 to 6 inches at 3,000 to 4,000 feet of elevation.
If essential travel is planned at higher elevations, it is critical to prepare for a significant amount of snow, sleet or ice accumulations.
