Phases of Emergency Management


Mitigation refers to actions taken before an event occurs to prevent or lessen the impact the event has to life and property. Examples of mitigation include; building codes, zoning ordinances, grant funding, and training.


Preparedness refers to activities, actions, procurements, planning, training and inter-jurisdictional cooperation designed to increase response readiness to identified hazards the community faces.


Response is the mobilization of resources to meet the needs of the community in response to the nature of the disaster. Mobilization includes local, county, state, and federal resources as necessary. Response is usually associated with the period of time immediately after the event and necessary to ensure life safety issues are handled. Examples include Fire and EMS services, search and rescue, debris removal, public works activities, and law enforcement.


Refers to long-term mobilization of support operations that work toward returning the community to its pre-event condition. This period is usually when social services and volunteer organizations tasked with relief effort gear up. The greater the magnitude of the disaster the greater the recovery effort

Outdoor / Severe Weather Warning Sirens

About the System

The City of Anna Outdoor Early Warning System consists of 4 outdoor warning sirens located throughout the City that are designed to inform residents who are outside of a possible emergency. The sirens may be activated individually or in small groups for a localized emergency or they all may be activated simultaneously for a city wide emergency. The sirens are part of an emergency system designed to provide immediate and valuable information to citizens. The system is not designed to alert those who are within a home or other structure.

What to do

If you hear the sirens while you are outside, please go inside and seek shelter immediately and refer to a television or radio for further instructions. Please do not call 9-1-1 for severe weather information. Call 9-1-1 only to report life-threatening situations.

Responding to Severe Weather

Learning to prepare for and respond to severe weather is a reality for those living in North Texas. When severe weather happens, it is imperative that an action plan is in place and every resident has a clear understanding of the Outdoor Early Warning System.

In addition to the warning sirens, we offer an emergency alert service through a system called Hyper-Reach.  You can access the Hyper-Reach signup page by following this link:
