(KMOV) – Soon after a tornado left University City, residents were questioning why they had not heard a siren until after the storm.
According to Mike Smiley, Director of Emergency Management, the sirens went off one minute after the National Weather Service issued a tornado warning. It is the county’s policy to not sound the alarms for severe thunderstorms or tornado watches, but only for tornado warnings.
Thursday’s tornado formed quickly and hit University City for the first time. Preliminary reports state that the twister formed in just two minutes and show an EF1 damage.
Emergency officials stress that the sirens are designed to alert people outside and are not intended to be heard inside the home.
