A Tornado Warning is an alert issued by meteorological authorities when a tornado has been sighted or indicated by radar. This warning means that a tornado is imminent or already occurring in the area, and people should take immediate action to protect themselves. During a Tornado Warning, individuals are advised to seek shelter in a sturdy building, preferably in a basement or an interior room away from windows. It is crucial to stay informed through local news or weather apps, as conditions can change rapidly. Always have an emergency plan in place to ensure safety during severe weather events.
