In 2019, the City of Katy implemented a Mass Notification System known as KTALERT. This system uses a "reverse dialing" telephone method to notify members of the public with critical emergency information in situations where property or human life is in danger and inform subscribers of events affecting them. 

In addition, the mass notification system provides enhanced notification capabilities to a subscriber's home, cell or business phone, as well as email, text messages, hearing impaired receiving devices and more at no cost. In other words, subscribers select where messages are sent and how they are received.

Notifications can be sent for air quality issues, crime alerts, power outages, road closures, mosquito control, water outages and weather-related issues such as ice and flooding.

If the City of Katy activated the system for an area that contains a location that has been registered to a particular cellphone or land line number, the system will attempt to send the emergency message to that phone. Notification messages are initiated by the local public safety agency as one of several methods of relaying vital information to citizens.


Visit the KTALERT and enter your contact information into the Notification System. If you are unable to register online, you can fill out the Manual Sign-Up Form and email it to oem@cityofkaty.com or mail it in. You can also call (281) 574-8633 for help. Callers will be prompted for their personal contact information.
