When you hear the sirens Tuesday, don’t worry: It’s only a drill.

As part of Severe Weather Awareness Week, Kansas will hold a tornado safety drill Tuesday at 1:30 p.m. and everyone is encouraged to take part. Participation is easy: When you hear the sirens, seek shelter.

All but seven counties in Kansas will hear the sirens Tuesday, according to the National Weather Service in Topeka. Johnson, Miami, Leavenworth, Wyandotte, Atchison, Denison and Linn counties will hold safety drills on Thursday along with Missouri.

March marks the beginning of testing season as well: Warning sirens in Douglas County are tested at noon on the first and third Monday of the month from March through July.

The idea is that practice makes perfect, but preparedness helps too: State emergency planners recommend getting together an emergency kit, have an emergency plan in place and make sure your family knows about it. For more tips, check out www.ksready.gov.
