Thunderstorms are rain showers accompanied by thunder and lightning. They typically last about 30 minutes but can persist longer depending on weather conditions. Commonly formed during the spring and summer months, thunderstorms are often initiated by convection. They can lead to severe consequences such as flash floods, tornadoes, and wildfires, making them more dangerous than hurricanes in terms of casualties. For more information about thunderstorms, visit NOAA's National Severe Storms Laboratory at www.nssl.noaa.gov.
