DES MOINES, Iowa (AP) – Three school districts in Iowa are set to receive federal funding for safe rooms in the event of a tornado.

The Federal Emergency Management Agency says it has approved nearly $3.3 million in funding for projects in Creston, Lenox and West Des Moines over the past three months.

The safe rooms will be designed to withstand winds of 250 miles per hour. They typically shelter an entire building’s population and are often used as gyms, cafeterias and libraries on a daily basis.
