Overview

Low pressure located over northern Minnesota the afternoon of July 7th led to the development of scattered showers and isolated thunderstorms over northeastern Minnesota and northwestern Wisconsin. Most of this activity was very shallow in nature and were not producing hail larger than peas or much in terms of wind gusts. One shower produced a waterspout over Lake Vermilion shortly before 2:30 PM CDT. Waterspouts and funnel clouds were possible across the region due to favorable atmospheric conditions in the vicinity of the low pressure center over the region. This survey was conducted utilizing photos and videos of the waterspout that were posted to social media and through interviews with witnesses. No injuries or fatalities were reported and the waterspout likely remained over open waters of Lake Vermilion.

This information is preliminary in nature and may be revised as we continue to review additional reports, images, and videos. NWS Duluth sincerely appreciates the photos and videos shared with us from the public of this event.
