Crystal Lake Siren Locations
The sirens are strategically located to provide the optimal coverage area for all City residents. In an effort to plan for tornado events, the City has sixteen outdoor warning sirens placed strategically throughout the City to warn the public. If you hear the sound of a warning siren, seek shelter immediately. The sirens will not be activated to indicate an "All Clear". The local news media provides any "All Clear" information.
Outdoor warning sirens are tested on the first Tuesday of each month at 10:00 AM for a one minute duration.
Watch vs. Warning
A Severe Thunderstorm Watch means severe weather is possible. A Tornado Watch means that conditions are present that could produce a tornado.
A Severe Thunderstorm Warning means that severe weather is in the immediate area. A Tornado Warning means that a tornado has been sighted, and that you should prepare to seek shelter.
