Intense thunderstorm lines can produce brief tornadoes and widespread
significant wind damage. Although a tornado is not immediately
likely, it is best to move to an interior room on the lowest floor of
a building. These storms may cause serious injury and significant
property damage.

In addition to large hail and damaging winds... frequent cloud to
ground lightning is occurring with this storm. Move indoors
immediately. Remember... if you can hear thunder... you are close
enough to be struck by lightning.
