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 A.M. and 12:30 P.M. As part of this drill, local jurisdictions across Texas may test systems used to notify the public during emergencies. Depending on the systems used by your local jurisdiction and/or the jurisdiction you are in at the time of the test, residents may receive a test alert on their mobile phone and/or hear outdoor warning sirens during this time. It is only a test - - again, between the times of 10:00 A.M. and 12:30 P.M. on April 2.
