Precautionary/preparedness actions...

A Blizzard Warning means severe winter weather conditions are expected or occurring. Falling and blowing snow with strong winds and poor visibilities are likely. This will lead to whiteout conditions... making travel extremely dangerous. Do not travel. If you must travel... have a winter survival kit with you. If you get stranded... stay with your vehicle.
