❓ Frequently Asked Questions
What is the difference between a tornado watch and a tornado warning?
A tornado watch means conditions are favorable for tornadoes to develop—monitor weather updates and be prepared to act. A tornado warning means a tornado has been sighted or detected by radar—take shelter immediately in your designated safe room. Watches cover large areas for several hours; warnings are more specific and urgent.
What should you do during a tornado?
Go to your designated safe room immediately—an interior room on the lowest floor, away from windows. Get under a sturdy piece of furniture or cover yourself with a mattress. Protect your head and neck. If in a mobile home, evacuate to a sturdy building or storm shelter before the storm arrives. Never try to outrun a tornado in a vehicle.
How much does a storm shelter cost?
Residential storm shelters typically cost $3,000 to $10,000 depending on size, type (above-ground vs. in-ground), and installation. Above-ground safe rooms may run $3,000–$6,000; in-ground shelters $5,000–$10,000. Some states offer rebates or tax incentives. FEMA provides guidance on shelter construction standards.
What is Tornado Alley?
Tornado Alley refers to the region from Texas through Oklahoma, Kansas, Nebraska, and into South Dakota where tornadoes are most frequent. Peak tornado season runs April through June, though tornadoes can occur year-round. The region experiences the highest concentration of severe thunderstorms and tornado activity in the United States.
What do the EF Scale ratings mean?
The Enhanced Fujita (EF) Scale rates tornado intensity by wind speed and damage: EF0 (65–85 mph, light damage), EF1 (86–110 mph, moderate), EF2 (111–135 mph, significant), EF3 (136–165 mph, severe), EF4 (166–200 mph, devastating), EF5 (200+ mph, incredible damage). Most tornadoes are EF0 or EF1; EF4 and EF5 are rare but cause catastrophic destruction.
Is it safe to shelter in a mobile home during a tornado?
No. Mobile homes offer little protection during tornadoes and can be overturned or destroyed even in weaker storms. Always evacuate to a sturdy building or designated storm shelter before severe weather arrives. Have a plan and know your route. Do not stay in a mobile home during a tornado warning.
