Strengthening Emergency Communication for our Community

The City of Manitowoc has refined its Outdoor Warning Siren Policy to align with both established safety standards and best practices and existing policy in place for the rest of Manitowoc County.  These updates ensure consistent activation protocols, standardized testing schedules, and clear public messaging.  By streamlining how and when sirens are used, we aim to reduce uncertainty, improve public awareness, and support timely, informed action during emergencies.

If a siren activates and no severe weather seems imminent, tune to local radio stations for more information on possible non-weather related emergencies.

Sirens are tested regularly to ensure they are operating properly on the first Wednesday of the month at noon.
