FLAGSTAFF — Full-volume testing of the Museum Fire/ Spruce Wash flood area siren alerting system is scheduled for Thursday, June 5 at 10 a.m. The testing will confirm the proper functioning of the sirens ahead of monsoon season. Testing may be postponed in the event of rain or smoke in the area.
During the testing, residents in the area will hear an alarm sound, followed by a voice message repeated three times in English, Spanish and Navajo, concluding with a wind down siren sound signifying the end of that message.
