The National Weather Service has confirmed that tornadoes struck near the southern Minnesota communities of Granada and Morristown.

Survey crews from the weather service fanned out across southern Minnesota on Friday to assess the damage from severe storms that struck Thursday evening, packing powerful winds and heavy rain. The hardest-hit area included Rice County, around 40 miles south of Minneapolis. But there were no immediate reports of injuries.

The Weather Service says radar data and spotter reports indicated a few additional tornadoes likely occurred with the storms, but it has not yet assigned ratings to any of the tornadoes.
