Outdoor Warning System

More Pages

The City maintains an Outdoor Warning System, a network of sirens located throughout the city that are used to alert the public of emergency situations. Sirens are tested the first Tuesday of each month at 10 a.m.

In the event of a citywide emergency, Emergency Services may use the city’s Outdoor Warning System, Community Access (cable) Channel 993, local radio and TV stations, NIXLE, or Madison County’s “reverse calling system”. Additionally, newspapers, handbills or emergency responders announcing information over vehicle based loud speakers may be used. It is important for citizens to listen to and follow directions provided over the Outdoor Warning System during severe weather and other emergency situations as this is one of the first sources of emergency information.

DO NOT call 911 unless you have an emergency to report. The dispatchers do not have time to answer your questions and your call may overload the system.
The National Oceanic and Atmospheric Administration (NOAA) broadcasts normal and emergency weather conditions on a weather alert radio system. These broadcasts may be monitored by purchasing a “Weather Radio”. In the past, Granite City ESDA has provided many such radios to local schools, nursing homes and mobile home occupants. These are no longer available through the city but may be purchased at many local retailers. We suggest every homeowner; renter and business owner maintain a weather radio to provide storm watches and warnings necessary for their own protection and that of their family.
