The City of Weatherford has 10 Outdoor Warning Sirens (see locations and map below). The first Wednesday of each month at 1 p.m., weather permitting. These tests will occur thereafter on the first Wednesday of each month in conjunction with the other DFW cities who test theirs during this time. The Outdoor Warning Sirens are designed to give people time to seek shelter. The monthly tests typically last for 3 minutes and all sirens are tested at the same time.
