The City of Keller maintains and operates 11 outdoor warning sirens, three of which have voice alerting. The first Wednesday of every month at 1 p.m. (weather permitting), the Keller Fire Department and Emergency Management Officer test these sirens.

An Outdoor Warning System consists of multiple sirens designed to alert and notify citizens of emergencies in “OUTDOOR AREAS.” These emergencies may include, but are not limited to, natural emergencies, transportation accidents involving hazardous material, emergencies at fixed facilities, acts of terrorism and other catastrophic events about which the community needs to be informed immediately. Citizens that are indoors should not mistakenly wait to hear a siren as their only source of warning information; turn on a television, radio or NOAA Weather radio for more specific community-related information.

Listed below are activation guidelines set forth by the North Central Texas Council of Governments and the Federal Emergency Management Agency.

Minimum Activation Guidelines:

1. The National Weather Service issues a Tornado Warning or Severe Thunderstorm Warning with the phrase “Destructive winds in excess of 70 mph (or higher) are likely with this storm” in your immediate area.

2. Trained storm spotters have reported a tornado within the city or in a neighboring city that has the potential to affect your community.

3. Hail has been reported in the size of 1.25-inches in diameter or greater. (1-inch hail may be more appropriate for areas or events where large numbers of people are outdoors.)

4. Any other emergency as directed by the community’s elected officials.
