The storm will impact the Sierra Nevada region, including Donner Pass, with high winds, rain, and snow. Valley areas will experience wind gusts over 40 mph, which could lead to localized turbulence and travel disruptions. Snow levels dropping to the foothills late Sunday into Monday may affect higher-elevation communities, though snowfall amounts are expected to be moderate. Travelers should prepare for changing road conditions, especially in mountain passes, and potential delays due to snow accumulation.
