Dakota County has changed its policy on when outdoor warning sirens are activated.

In the past, the sirens were sounded during tornado warnings and any severe thunderstorm warnings. Sirens were activated 96 times from 2010- to 2014, the Sheriff's Office said.

Under the new policy, effective immediately, sirens will be activated during tornado warnings, as usual, but only when sustained wind speeds reach 70 or more miles per hour during severe thunderstorm warnings.

Local police and fire departments also can have the sirens activated if they believe it is in the best interest of public safety, such as a funnel cloud sighting when no warnings have been issued.

The change was made after a recommendation from the National Weather Service, based on more accurate weather forecasting and technology, as well as wind damage information. If the policy had been in use over the past five years, the use of sirens would have been reduced by 75 percent, the Sheriff's Office said.
