If the tornado siren down the block suddenly begins to wail in the next few days, it probably won’t be necessary to rush to the basement that very instant. It’s unlikely to be cause for alarm.
Naperville will conduct routine maintenance on its 25 outdoor warning sirens the week of Oct. 7-11, activating each one separately to see how it’s working. The process will take place between 8 a.m. and 5 p.m. each day.
“Residents should not be alarmed if they hear the sirens going off during periods of calm weather,” advises a news release sent by the city that explains the need to ensure the system is functioning correctly, should a weather emergency happen.
“This year’s scope of work includes maintenance to ensure that each siren’s radio, which both receives commands and reports the siren’s status to public safety personnel continuously, is working properly,” said Dan Nelson, emergency management coordinator, in the release.
The warning sirens are activated to notify people who are outside that it’s time to take cover when a tornado has been spotted in the area. Residents also are advised to monitor local media, weather radio sponsored by the National Oceanic and Atmospheric Administration or the National Weather Service website, www.weather.gov, which is operating in a modified capacity during the federal government shutdown.
