The Lightning Detection System is now operational on Fields 1-5 and Willow Field. There are signs posted that explain exactly how it works. Please read them.
As a summary the siren and strobe light is on the light pole on Field 1 and can be heard and seen from all the Rec Fields (#1-5). The siren and strobe light on Willow field is on a light pole there. As the signs indicate when the siren sounds you must immediately leave the field and take shelter in a protected area which in most instances will be a car. Under no circumstances should you stand under a tree, near a fence or near a pole. When the siren sounds the strobe light will flash indicating there is lighting in in the area. When the siren sounds again, after 30 minutes at least, and the strobe light goes off you can go back to the field.
While this system is a helpful aid it should not replace your judgment with regard to being more cautious. When in doubt cancel the game or practice and send everyone home.
