Press Release: “[Prince William County Public Schools] is activating a new severe weather alert system in all our middle and high schools to keep our students and staff safe during after-school activities. This is part of our commitment to providing safe and welcoming facilities to our students, families, staff, and community.”
“This new system, Perry Weather, can detect wind chill, lightning, and pinpoint dangerous heat and WetBulb Globe Temperature (WBGT) conditions in the air. If lightning is detected within 10 miles of a middle or high school, a siren will sound a 15 second initial warning, and a strobe light will begin flashing on the system.”
