Outdoor Warning System Activation for Severe Weather Alerts
Technical BulletinLast updated Tuesday, October 2, 2012The problem to be addressed by this Applied Research Project (ARP) was that the City of Burleson has adopted an Outdoor Warning System (OWS) activation policy for severe weather events that has lead to frequent activation of the OWS system. Frequent activation may negatively impact public perception of the reliability and accuracy of the OWS system. The purpose of this Applied Research Project (ARP) was to identify the impact the OWS policy has on Citizens in the City of Burleson. Descriptive research methodology was used to complete this task.Four research questions were developed to drive the research: (a) What effect does frequent OWS siren activation for severe weather have upon citizens; (b) What is the threat perception of citizens once the sirens stop sounding; (c) When should the OWS be activated for severe thunderstorms; and (d) What influence could different OWS warning tones/messages have upon residents? Two procedures were used for this research: a citizen/workforce survey and personal interviews with emergency management staff, policy makers and stakeholders. The results of the research revealed several policy suggestions that should be included and/or changed in the current OWS policy.It was recommended that the City of Burleson revise the current OWS activation guidelines for severe weather by: (a) narrowing the "alert zone" to the city limits only, (b) consider selected activation by area instead of activating the entire system, (c) attempt to limit false alarms by having a standard deemed acceptable by policy makers, and (d) begin a public education campaign to educate the public on the use of the OWS system.
