DES MOINES, Iowa — Iowans are encouraged to practice their severe-weather plans on Wednesday.

Outdoor warning sirens will sound at 10:00 a.m. as part of the statewide Tornado Drill. It’s a way to test the system and give people a chance to prepare better for severe weather.

The sirens are designed to alert people who are outdoors when severe weather strikes, not those who are indoors. If you are outside and hear the sirens, seek shelter immediately.

Polk County Emergency Management says that during severe weather season, you should stay informed, have a plan, and a kit with emergency supplies. They also say you should have multiple ways of receiving weather watches and warnings, like apps, TV, and a weather radio.
