How to Prepare for a Snowstorm – A Winter Storm Checklist

A winter storm, like any other major weather event, can keep you trapped for days without power. How do you prepare for a snowstorm? Know what to do before, during, and after a blizzard with these preparedness tips.

Know Your Winter Storm Warning Levels

Get acquainted with these winter storm watch terms and definitions from the National Weather Service. Becoming familiar with these terms will help you act quickly and prep accordingly just before a snowy weather event.

  • Winter Storm Watch
    There is a potential for hazardous winter weather within 36 to 48 hours. Keep tracking weather news, review your storm plan, and get preparations in place.
  • Winter Weather Advisory
    Current winter conditions are expected to cause significant inconveniences but are not severe enough to issue a warning.
  • Winter Storm Warning
    Hazardous and potentially life-threatening winter weather is currently happening or will happen within 24 hours. The National Weather Service will issue a warning when a combination of snow, ice, and wind damage conditions are met.

Prepare Before a Snowstorm

Try to prepare your home for winter before the first snowfall. The key to keeping your family safe and comfortable during a blizzard is to have a storm plan in place well before you have to use it.

  • If you live in a very snowy place, it may be a good idea to invest in a generator. In the event of a winter power outage, a reliable generator and a good fuel supply can make a huge difference.
  • Create a winter home emergency kit. You can use the supply list by the American Red Cross as a guide.
  • Inspect and/or clean your chimney before winter.

What to Do Just Before a Snowstorm

When the National Weather Service issues a Winter Storm Watch, it’s wise to start taking precautions for a bigger storm, just in case.

  • Stock up on fuel for the generator.
  • Charge your phones, electronics, rechargeable batteries, and power banks.
  • Make sure flashlights are easily accessible.

What to Do During a Snowstorm

During a winter storm warning, the temperature can drop to below 25 Fahrenheit and snow can reach 5 inches or more within 12 hours. In a worst-case scenario, ice and wind can damage electricity lines.

  • Unplug computers and other non-essential electrical equipment to avoid a power surge.
  • Keep the freezer and refrigerator door closed to keep food from spoiling.
  • For extended periods of no electricity, move perishables to garage to stay frozen.
  • Use flashlights to avoid a risk of a fire.
  • When cooking, be mindful of fumes and carbon monoxide poisoning.
  • Have family members dress in layers, and use blankets and towels for extra warmth.
  • Listen for weather updates on the weather radio..

What to Do After a Snowstorm

You’ve weathered the winter storm: now it’s time to clean up and get back to the day-to-day normal.

  • Handle your generator safely to avoid electrocution, carbon monoxide poisoning, or fire.
  • Continue to listen to the local news or the weather radio for updates and closures.
  • Use sand, ice melt, or kitty litter to add traction to slippery surfaces.
