Ottawa sits in a part of Kansas where severe weather planning is not optional. Tornadoes, large hail, lightning, flash flooding, and winter storms all belong in a basic household preparedness plan.
The most useful starting steps are simple: have more than one way to receive alerts, know your shelter area, keep a three-day emergency kit, and make sure everyone in the house knows what to do when a warning is issued. Flooded roads and lightning also deserve the same level of caution as tornadoes.
