Forsyth County EMA to Use Warning Tone During Monthly Siren Tests March 3, 2019 EMA, Photo Beginning in March, Forsyth County will replace the severe weather siren “test tone” with a “warning tone” for all monthly siren tests. Previously, the county’s monthly siren tests, held at noon on the first Wednesday of every month (weather permitting), would feature a test tone while the warning tone was reserved to be used exclusively in the event of an actual tornado warning. “The decision to begin conducting the siren tests with the warning tone instead of the test tone was made to help avoid confusion and to help residents recognize what the alarm signifies should there be an actually tornado warning in the county,” said EMA Director Chris Grimes. The next siren test is scheduled for noon on Wednesday, March 6 (weather permitting). Forsyth County has 17 outdoor severe weather sirens located throughout the county to notify residents that severe weather is in the area. Severe weather sirens are only designed to be heard by individuals outside during severe weather. Residents should have other means of receiving severe weather notification when located inside a structure.
