Public Information Statement
Statement as of 8:00 am CDT on April 23, 2014

...This week is tornado and severe weather awareness week in Wisconsin...

Severe thunderstorms contain multiple dangers that can threaten your safety and personal property in any part of the country and at any time of the year. Although these storms can be fairly small... averaging around 10 to 15 miles in diameter...and have an average lifetime of 20 to 30 minutes...they can cause a tremendous amount of damage in a short amount of time.

Severe thunderstorms are defined as having one or more of the following:

* wind gusts near 60 miles per hour or greater

* hail at least one inch in diameter (the size of a quarter)

* a tornado

All thunderstorms...whether severe or not...contain dangerous lightning.

Severe thunderstorms occur much more frequently than tornadoes. If the National Weather Service issues a Severe Thunderstorm Warning... you need to take action to protect yourself. Move to a sturdy building and do not stand near windows. Always remember that thunderstorms can produce tornadoes with little or no advance warning.

Always monitor current and forecast weather conditions...and keep up to date on the latest severe weather watches and warnings...by listening to NOAA Weather Radio...the voice of noaa's National Weather Service.
