As storm season arrives, you may occasionally hear the City of Lampasas warning sirens alerting you to severe weather, but what do the sirens mean? City of Lampasas, sirens go off for tornadoes, thunderstorms accompanied by winds of 70 mph or higher, or hail that is golf ball sized or larger. All alerts will be sounded by the Lampasas Fire Department or the Lampasas Police Department when they receive word that severe weather is approaching. No matter the kind of weather, sirens will sound with the same tone. Sirens may be sounded multiple times for the same severe weather threats. There is no all-clear signal from sirens. If you hear a siren, the best reaction is to go indoors to the most center part of the structure away from windows (ex. Bathroom or closet) and tune in to local media for information. You may not be able to hear a siren if you are indoors. The sirens are designed to alert people who are outside that something dangerous is approaching. The City of Lampasas will issue a notice when weather sirens are to be tested. In the event that there is a severe weather watch or warning issued in the area on a scheduled testing day, testing will be postponed until a later time and date. If you have any questions please call the Lampasas Fire Department 512-556-3446.
