Lockhart Community News
Outdoor Warning Siren test scheduled for 1 p.m. today (December 7)

The 5-siren outdoor warning system emits a steady, loud noise to alert Lockhart residents who are outdoors of approaching or existing hazardous conditions which require immediate protective actions in order to save lives. These systems are often mistakenly referred to as "tornado sirens," but that term fails to acknowledge all applications for activating sirens. We refer to these sirens as Outdoor Warning Sirens to reinforce the multiple conditions for which the sirens are activated.


If you are outside when you hear the Outdoor Warning Sirens, you are urged to move indoors and seek shelter on the lowest floor and an interior room with no windows and seek additional information from local TV or radio stations.   


The Outdoor Warning Siren activates in the following scenarios :

  • The National Weather Service (NWS) issues a Tornado Warning.
  •  The National Weather Service (NWS) issues a Severe Thunderstorm Warning and indicates the potential for destructive winds of 70 mph or greater.
  • Observed hail of 1.5 inches in diameter (ping pong ball size) or greater.
  •  Any observed weather condition, which is judged to be hazardous to people and early warning would potentially save lives. For example, the sirens may be activated in response to hail that is less than 1.5 inches if there are a large number of people concentrated outdoors at an event.
  • Chemical emergencies.



The sirens are tested on the first Monday of each month at 1 p.m. Sirens will not be tested during a severe weather event or if a special event is being held. Canceled tests will not be rescheduled.




The siren system is not intended to notify residents who are already indoors. We encourage you to sign up for the Warn Central Texas Notification System. This is a Regional Notification System developed for Central Texas and administered by the Capital Area Council of Governments (CAPCOG). The warning system will notify citizens of Lockhart by phone call, text or email for emergencies such as; Tornados, severe weather, flooding, and local emergency information.


You may register to receive the free emergency alerts or community information via text, e-mail, or phone at warncentraltexas.org
