Thunderstorms that settled over northeastern Minnesota dumped rain at the rate of two inches an hour in some places. Several Iron Range towns were under water by evening and the flooding spread eastward overnight. The Duluth News Tribune maintained a live blog.
The storms arrived on the Range after pelting areas such as Detroit Lakes with hail.
Lake Country Power reported more than 1,000 customers has lost electricity by early evening. That’s a familiar problem across Minnesota. In areas south of the Twin Cities more than 100,000 lost power during the storm of Monday night and Tuesday morning. Xcel Energy called in extra crews from Iowa and Wisconsin to help get the lights back on.
Wind damage was not confined to trees and power lines. In Hastings the wind pulled off part of the roof of a senior housing complex, triggering the sprinkler system which then caused water damage.
In south central Minnesota the greatest damage seemed to be from hail, but farmers are still sizing up the effect on crops.
