Overview
McKinney's Outdoor Warning Siren (OWS) system is designed to notify residents and visitors who are outdoors of potential hazards, weather and other emergencies. The system is maintained by the McKinney Office of Emergency Management and comprises 28 sirens strategically located throughout the city to sound alerts.
When the city activates the Outdoor Warning Sirens, move indoors, seek more information and monitor TV, radio or other media for necessary actions.
