According to Federal Emergency Management Agency (FEMA), you should have a tornado safety plan:

• Shelter Area: Designate an area in your home where you want to take shelter. Everybody in the family should know about that area. Keep the shelter area uncluttered.

• Tornado Practice Drills: Conduct tornado practice drills so  everybody in the family know to go to the selected shelter area as a response to the tornado threat.

• Watch & Warning: Discuss with family members the difference between a “tornado watch” & a “tornado warning”.

• Communication Plan: Make an out-of-state relative or a friend as your “emergency family contact”. By only calling a single person after a tornado it helps local phone systems from crashing. Make sure that everybody in the family knows the name, address, and contact number of that person. This may be especially helpful if any of the members is separated from the family during the tornado. It is real possibility because adults may be at home/office and children may be in school.
