Severe Weather Siren
The Village of Spring Grove maintains and operates a community-wide outdoor severe weather warning system. This system is designed to warn residents of an approaching tornado or extremely dangerous weather. The system can be activated by the Spring Grove Police Department and designated fire district officials from police and fire vehicles. It can also be activated by McHenry County E.S.D.A. from their base.
In the event of threatening weather, officers carefully observe approaching storms and monitor local emergency services and civilian radio frequencies to determine the threat of danger. If it is determined that the outdoor warning system should be activated the sirens are activated and will continue a steady blast for 3 minutes.
The first Tuesday of every month the Village will test the Outdoor Weather Warning System.
The system will be activated at approximately 10:30 a.m. and will sound a solid blast siren for three minutes. Any questions about the system should be referred to the Police Department.

WATCHES VS. WARNINGS
WHAT'S THE DIFFERENCE?
A watch means that conditions are right for a severe weather event to occur. A warning means that the event is currently taking place nearby. In Spring Grove, the emergency warning sirens are activated in the event of a tornado warning. Spring Grove residents should also keep in mind that the Village DOES NOT give an "all clear" signal.
UPON HEARING A WARNING SIREN, YOU SHOULD:
- Go at once to the basement or interior part of the building on the lowest level.
- Stay away from windows.
- Go to the center of the room.
- Get under a piece of sturdy furniture such as a workbench or heavy table, and hold onto it.
- Use arms to protect head and neck.
- Use pillows, mattresses or cushions to protect your head and neck.
