ESDA/Warning Sirens
Gridley has established an Emergency Service Disaster Agency (ESDA) to warn its residents and the residents of Meadows, Illinois of disasters, whether man-made or natural causes.
When a tornado is spotted by the Gridley ESDA, and the Gridley area is in the path, a siren will sound for one steady blast. This will be done each time a tornado is spotted. The steady blast means “take cover immediately, a tornado is approaching.”
It is advised to have a battery-powered radio on hand to listen to the details when the electricity is off.
The tornado siren is tested on the first Tuesday of each month at 10 am unless severe weather is in the area.
Gridley’s ESDA director is: Kathy Ellis
