Intense thunderstorm lines can produce brief tornadoes and widespread

a building. This storm may cause serious injury and significant
property damage.
Large hail, damaging winds, and continuous cloud to ground lightning
are occurring with this storm. Move indoors immediately. Lightning is
one of nature's leading killers. Remember, if you can hear thunder,
you are close enough to be struck by lightning.
