APPLETON, WI (WTAQ) - Storm warning sirens are operating again in Outagamie County.
Emergency management director Julie Loeffelholz says regular tests of all 47 sirens will resume at noon tomorrow.
New radio systems have been installed in all the sirens -- which did not alert people in time to get out of the way of heavy storms and tornadoes in early August.
Loeffelholz recently said a tower that controls the sirens lost power before she could order the sirens be activated.
She urges people not to rely only on the outdoor warnings for storm warnings.
Up-to-the-second information is also available on National Weather Service radios, smartphone apps, and local broadcasts.
