What the agency told people to do
Seek shelter inside a well-built structure and stay away from windows. These storms are capable of producing large hail. Continuous cloud to ground lightning is occurring with these storms. Lightning is one of nature's leading killers. Remember, if you can hear thunder, you are close enough to be struck by lightning. Torrential rainfall is also occurring with these storms and may lead to flash flooding. Do not drive your vehicle through flooded roadways.
