A Severe Thunderstorm Warning is issued by the National Weather Service when a thunderstorm is producing severe weather conditions. This includes strong winds of 58 miles per hour or higher, large hail, or tornadoes. The warning indicates that these dangerous conditions are either occurring or imminent in a specific area. When a Severe Thunderstorm Warning is in effect, it is important to take precautions. Seek shelter indoors, away from windows, and stay tuned to local weather updates. Being prepared can help ensure safety during severe weather events associated with thunderstorms, such as flash flooding and power outages.
