Introduction: Lancaster County, Nebraska, experiences tornadoes as it lies within “Tornado Alley.” This is an area prone to these types of natural disasters due to its flat terrain, which allows warm, moist air from the Gulf of Mexico to mix with cool, dry air from Canada. This interaction creates atmospheric instability, leading to the formation of tornadoes. On average, Lancaster County experiences 1 to 3 tornadoes per year.
This Emergency Operations Plan provides a comprehensive guideline and a plan of action for Nebraska emergency officials in the case of a tornado to decrease the risk of adverse impacts to Lancaster County.
