Above-ground tornado shelters are a safe option for those without basements or in areas prone to severe weather. However, underground shelters may face risks such as flooding or blocked exits, especially in flood-prone areas. Homeowners should carefully consider their location and the potential hazards when choosing a shelter type. The cost of installation may also be a factor for some families, with prices ranging significantly based on size and design. Despite these considerations, approved safe rooms have a strong track record of preventing fatalities during tornadoes.
