Watches, Warnings, and What To Do

In the event of a Weather Emergency, Winnebago County emergency sirens will activate. At this point, it will be determined if the Event, or portions of the Event, should be postponed or cancelled and the grounds should be Evacuated – this will be a joint decision made by EAA Senior Leadership, the Winnebago County Sheriff’s Department, and Winnebago County Emergency Management.

There are typically NO buildings or shelters available, for Guests, Vendors, Performers, Volunteers, and EAA Employees, should a Weather Emergency occur.

Guests, Vendors, Performers, Volunteers, and EAA Employees have the option to shelter in place in their campsite (if they are camping), a low-lying area or, if feasible, in their vehicle.

If the Guests, Vendors, Performers, Volunteers, and EAA Employees choose to shelter in a low-lying area, they should find a low spot away from trees, fences, and poles, but make sure the spot is not prone to flash flooding. The Guests, Vendors, Performers, Volunteers, and EAA Employees should cover their head with their hands and lie face down on the ground.

If the Guests, Vendors, Performers, Volunteers, and EAA Employees choose to take shelter in their vehicle, it is recommended that they crouch below the window line and turn the engine on. This will allow the vehicle's airbags to be deployed.
