Officials in the Virginia area are discussing what should be done about malfunctioning tornado sirens.
During tornado alerts Monday evening, some of Virginia's warning sirens didn't go off.
While funnel clouds were reported, no tornadoes touched down.
Virginia Mayor Steve Peterson says it's a wake-up call for the city.
Some of Virginia's sirens are more than 40 years old.
Peterson says Virginia will likely have to replace the sirens, because it doesn't make much sense to repair such old equipment.
In nearby Eveleth, the sirens did sound.
But sirens in Gilbert were silent because of a mix-up, and Mountain Iron doesn't have an alarm system.
