Wireless Emergency Alerts (WEA)

Emergencies don’t care where you are – they can happen when you’re at work, school, at home, or on vacation. The Wireless Emergency Alerts (WEA) system was developed to help inform the public in a specific area of emergency situations that require them to take action quickly to avoid injury.
The City of Houston has access to WEA for very serious, life-threatening emergencies. Additionally, you may also receive notifications from Federal State Agencies, and neighboring local agencies.

The National Weather Service issues WEA messages for the following situations:

  • Tsunami Warning
  • Tornado Warning
  • Extreme Wind warning
  • Flash Flood Warning
  • Hurricane Warning
  • Typhoon Warning
  • Blizzard Warning
  • Ice Storm Warning
  • Dust Storm Warning
  • Child Abduction Emergencies (AMBER Alerts)*

* AMBER Alerts are issued by NWS on behalf of the Texas Department of Public Safety (DPS) or the Houston Regional AMBER Alert Program

The City of Houston may issue a WEA warning for:

  • Terrorist Activity
  • Citywide Weather Emergencies
  • Evacuation Orders
  • Shelter-in-Place Emergencies
  • Other emergencies which require action to protect life

Your phone is likely already opted-in to receive WEA messages. If you’ve opted out, please make sure you opt-back in. These messages could save your life.
