Residents are urged to stay indoors until conditions improve. If you must go outside, dress in multiple layers of clothing to maintain body heat and cover exposed skin to reduce the risk of frostbite or hypothermia.
Travel should be delayed if possible. Motorists who must travel should use extreme caution as roads, bridges, and overpasses will likely become slick and hazardous. Visibility may drop below 1/4 mile due to falling and blowing snow, which will significantly impact the Monday morning and evening commutes. Additionally, strong winds and the weight of snow may down tree branches and power lines, causing sporadic power outages. For the latest road conditions, residents can call 5-1-1.
