Sirens are sounding over my area, but I did not receive an alert. Why not?

SW+ Alerts technology will only alert you when your registered location is in the path of the storm, as defined by the National Weather Service. In many locations, sirens are sounded county-wide when a Tornado Warning is in effect for any part of that county, even if your community is not impacted by the warning. SW+ Alerts uses your location’s latitude/longitude location and the NWS storm-based warning polygon to warn only the affected area, thereby reducing the false alarm rate, while still keeping you safe from the storm! This warning technique has received the approval of the NWS.
