Take Shelter Immediately

This is the time of year that tornadoes crop up in this part of the world fairly regularly.  There are multiple warning systems in place, including TV, radio, and even personal messages to the cell phone.  Some communities use sirens, others use announcement by emergency vehicles, including police and fire department vehicles. 

Whatever the method, if the warning words are pronounced "Take Shelter Immediately" then that is exactly what you should do. Do not waste any time.
