The following is a clarification on the use of weather alert sirens for the city of Olney: 
• Emergency Management Coordinator Ronnie Cowart said when inclement weather is in the area, the city's siren system will ONLY be used when residents are advised to take cover. They will not be sounded for any type of fire. 
• There is no longer a prolonged weather siren used to signal a possible tornado. An intermittent siren will sound to warn residents to take cover. 
• There is NO all-clear siren blown. Rely on TV weather alerts, weather radios, cable television break-in alerts and police scanners to know when it is safe to come out of shelter. Do not rely solely on traditional radio, Cowart said, as stations today frequently use pre-recorded content. 
• Sign up for weather alerts online at registry.i-info.com/rc/ntrc to receive up-to-date weather watches and warnings by text or email as they are issued.
