Be aware, residents! Tornado siren testing will take place in Norcross tomorrow, August 12, and Wednesday, August 13. The forecast shows rain most of Tuesday and cloudy skies Wednesday, so it’s important to stress that sirens are sounding only for testing purposes—there is no active severe weather or tornado threat. Sirens will be activated at various locations across the city at different times on both days. We appreciate your patience and understanding during this testing period.
