The City of West Fargo warning sirens will be tested Monday, Nov. 20. Beginning at 9 a.m., each of the 10 sirens in West Fargo will be set off independently and sound for approximately 10 seconds. This allows technicians to check the batteries, siren functions, speakers, siren rotation and cabinet condition. Generally, the testing will start with sirens north of Interstate 94 and move south. The testing is estimated to be completed by 5 p.m. that day, barring any weather or technological delays.
