What is a Blizzard?


In many areas of the world, winters mean heavy snowfall and very cold weather. Heavy snow can block roads, close schools, and cause tree limbs or power lines to fall down. The cold temperatures can be dangerous if you are not dressed correctly.

How Blizzards Effect Communities...

Blizzards produce lots of snow and sometimes ice. They can cause dangerous driving conditions and may even lead to closed schools and roadways.

Important Terms:

Freezing rain: Rain that freezes when it hits the ground, creating a coating of ice on roads and walkways.

Sleet: Rain that turns to ice pellets before reaching the ground. Sleet also causes roads to freeze and become slippery.

Winter Weather Advisory: Cold, ice and snow are expected.

Winter Storm Watch: Severe weather such as heavy snow or ice is possible in the next day or two.

Winter Storm Warning: Severe winter conditions have begun or will begin very soon.

Blizzard Warning: Heavy snow and strong winds will produce a blinding snow, near zero visibility, deep drifts and life-threatening wind chill.

Frost/Freeze Warning: Below freezing temperatures are expected.

What Can You Do ...

Winter Weather Makes Driving More Difficult

Roads can be slippery when ice and snow are on the ground, and falling snow or heavy rain can make it hard to see when driving. Here are some things you can do to be prepared:
  • Make sure you have the correct supplies in your family car. You should have in your trunk blankets, warm clothing, booster cables and tools, bottled water, some snacks, a first aid kit, flashlight and batteries, a shovel and ice scrapers. It's also a good idea to have a colorful scarf or piece of bright cloth to tie to your radio antennae to signal that you need help.

If you are caught in a storm or blizzard and your car becomes stuck, it is important to stay in the car and wait for someone to come rescue you. Only leave the car and walk for help if you can see a definite safe place within a reasonable distance.

When you are waiting in your car, turn on the engine for brief periods to provide heat, but always leave a window open slightly to avoid carbon monoxide poisoning. Also, make sure the exhaust pipe is clear of snow.
