On Thursday, April 2, 2026, at the request of Texas Division of Emergency Management (TDEM), a statewide test of emergency alerting systems will occur between 10:00 AM and 12:30 PM. As part of this drill, local jurisdictions across Texas may test systems used to notify the public during emergencies. Depending on the jurisdiction you are in at the time of test, you may receive a test alert on your mobile phone and/or hear outdoor warning sirens. The City of Lancaster will activate our emergency notifications system and sound our outdoor warning sirens during this time.
Please note: Because jurisdictions across the region may participate in this test, you may receive more than one test alert on your phone during the testing window.
This will only be a test. No emergency action is required.
Testing helps ensure emergency alert systems function properly and allows agencies to evaluate how alerts are delivered during real emergencies.
