SIU Alerts are messages about an emergency. The message may alert you to an emergency situation, ask you to take action, or both. Any information about flash floods, severe thunderstorms, winter storms, tornadoes, etc. will also be sent as an SIU Alert.
Please note that no communication distribution method is infallible. For that reason, SIU uses redundant systems of emergency communication, including telephone, Internet, e-mail, radio, loudspeakers, person to person, and text messaging, to distribute news and instructions during an emergency.
Before an emergency arrives, please make yourself aware of all of the distribution methods.
