The season’s first heavy thunderstorms were taking aim at the Northland area late Monday morning with the National Weather Service in Duluth issuing severe thunderstorm warnings.
The Weather Service said the line of strong thunderstorms could include large hail, high wind and heavy downpours.
The thunderstorms stretched along a line from near Bemidji to near Grantsburg, Wisconsin at 10:30 a.m. and were expected to move into Carlton and Douglas Counties by 11 a.m.
Areas to the south of the Twin Ports — including Hayward, Hinckley and Aitkin — are under a severe thunderstorm watch until 1 p.m.
