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. Excerpted from ready.gov.
Before winter approaches, add the following supplies to your emergency kit:
Rock salt or more environmentally safe products to melt ice on walkways
Sand to improve traction
Snow shovels and other snow removal equipment
Sufficient heating fuel
You may become isolated in your home and regular fuel sources may be cut off
Store a good supply of dry, seasoned wood for your fireplace or wood-burning stove
