At the request of Texas Division of Emergency Management (TDEM), there will be a statewide test of emergency alerting systems on Thursday, April 2, 2026.
As part of this drill, you may hear regional outdoor warning sirens and receive a test alert on your mobile phone and/or other small device between 10 a.m. and 12:30 p.m. The City of Arlington’s Office of Emergency Management will conduct the regularly scheduled test of the Outdoor Warning Sirens on Wednesday, April 1 at 1 p.m.
This will only be a test. No emergency action is required.
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.
Testing helps ensure emergency alert systems function properly and allows agencies to evaluate how alerts are delivered during real emergencies.
