San Marcos emergency management officials will test emergency sirens throughout the city Tuesday afternoon, Nov. 3 and throughout the day on Wednesday, Nov. 4. City crews are repairing sirens damaged in last Friday’s storms and will be activating the sirens to test the repairs.

The city will not test the warning system if severe weather is in the forecast for the day.

  • The warning system will be activated when:
  • The National Weather Service issues a San Marcos area tornado warning or severe thunderstorm warning with destructive winds at or above 70 mph
  • Trained storm spotters have reported a tornado with the potential to affect the City of San Marcos
  • Hail of 1.25 inches (about the size of a half-dollar) in diameter is imminent
  • Deemed necessary by City of San Marcos officials (i.e. in the event of any emergency when officials need citizens to move indoors for their safety)

During an emergency

In the event of a tornado warning residents, will hear a 3-to 5-minute steady signal of the sirens. When you hear the sirens during bad weather, go indoors and seek shelter in the most interior room in your home or office. You should avoid the outside walls and windows. An interior bathroom, closet, or other room is generally the safest location.

If you have access to a radio or television, turn it on to a local channel to listen for essential emergency information. All local channels will interrupt programming to issue tornado warnings and advise you where the tornado is located. Please do not call local fire or police agencies to ask why the sirens are sounding unless immediate assistance is needed.
