Statewide Emergency Alert System Test Scheduled for Thursday, April 2

TDEM has requested a statewide emergency alert system test for Thursday, April 2, 2026. The exercise will run during a set testing window. Residents may hear outdoor warning sirens or receive test alerts on mobile phones and other small devices.

Testing window and alerts

The statewide test is scheduled between 10 a.m. and 12:30 p.m. Central time. Multiple jurisdictions may participate. You could receive more than one test alert on a single device.

Arlington siren test

The City of Arlington’s Office of Emergency Management will run its regular outdoor warning siren test on Wednesday, April 1 at 1 p.m. This event is separate from the statewide drill. No emergency response is required for either test.

What residents should expect

Expect regional outdoor warning sirens and mobile notifications during the testing window. Notices may appear on phones and other small devices. Agencies advise remaining calm when seeing or hearing test alerts.

Multiple alerts and overlap

Because many jurisdictions will take part, you may receive duplicate alerts. Each alert is a test. It helps authorities confirm message reach across systems.

Why the test matters

Testing verifies that emergency alert systems function correctly. It also lets agencies evaluate how alerts reach the public during real incidents. Regular drills improve coordination between local and state partners.
