Mason City Outdoor Warning System

New Outdoor Warning Sirens installed in 2007The City of Mason City has a state-of-the-art outdoor warning system which was replaced with all new equipment in 2007.  This warning system was designed to warn citizens of Mason City who are outdoors of an impending weather or other emergency so that they can get indoors to safety and to tune to radio or television for more information about the emergency.  The warning system was not designed or was it intended to be heard indoors throughout the City. 


Sirens are tested the first Monday of every month around 10:00 a.m. unless the National Weather Service has issued a weather advisory.  If such a weather advisory has been issued, then the sirens are tested the following Monday. 


If citizens notice a siren not working, they are encouraged to contact the Mason City Fire Department (641.421.3640) to report the problem.
