McKinney has installed lightning strike detectors for seven fields, including Grady Littlejohn Softball and Baseball Complex. Each detector has its own weather station and a public address system. A siren will sound if there is lightning in the area. On this page, if the rectangle is green, the fields at this park are clear. If the rectangle is red, lightning is in the area. The message will also be shown in words. This widget will refresh every five minutes.
