Weather safety tips: Tornado guide

Tornadoes are the most violent atmospheric phenomenon on the planet. Winds of 200 to 300 miles per hour can occur with the most violent tornadoes. Notification of impending tornadic activity is issued in the form of a tornado watch or warning.

These destructive forces of nature are found most frequently in the United States east of the Rocky Mountains during the spring and summer months. In an average year, 800 tornadoes are reported nationwide. A tornado is defined as a violently rotating column of air extending from a thunderstorm to the ground.

Tornado damage paths can be in excess of one mile wide and 50 miles long.

May 12, 2000 marks one of the worst storms ever in Northeast Wisconsin. An F0 tornado touched down in St. Nazianz hitting a mobile home park. The storm also dropped quarter sized hail; other parts witnessed even larger hail the sized of a tennis ball.

What to do to prepare for a tornado:

• Develop a plan for you and your family for home, work, school and when outdoors.
• Have frequent drills.
• Know the county in which you live, and keep a highway map nearby to follow storm movement from weather bulletins.
• Have a NOAA Weather Radio with a warning alarm tone and battery back-up to receive warnings.
• Listen to radio and television or log onto the internet for information.
• If planning a trip outdoors, listen to the latest forecasts and take necessary action if threatening weather is possible.

Environmental Cues - What to watch for:

• Dark, often greenish sky
• Wall cloud
• Large hail
• Loud roar; similar to a freight train

If a tornado approaches:

• In a home or building, move to a pre-designated shelter, such as a basement.
• If an underground shelter is not available, move to an interior room or hallway on the lowest floor and get under a sturdy piece of furniture.
• Bring a battery-operated radio with you to your shelter
• Stay away from windows, doors and outside walls.
• Get out of automobiles.
• Mobile homes, even if tied down, offer little protection from tornadoes and should be abandoned.
• Do not open windows (this does not protect
• buildings from tornado damage).
• Find an interior room on the lowest floor, if there is no basement.
• Cover yourself in blankets, towels or anything that will protect you from flying debris.
• If you are in a car or mobile home, get out immediately. Most deaths during tornadoes occur in cars and mobile homes.
• If no suitable structure is nearby, lie flat, face down, in the nearest ditch or depression and use your hands to cover your head to protect against flying debris
