...NWS Damage Survey for 07/07/2024 Lake Vermilion Waterspout

Low pressure located over northern Minnesota the afternoon of the
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.

The waterspout developed to the northwest of Echo Point and west
of Ely Island on eastern Lake Vermilion. Based on radar and video
of the waterspout, it moved slowly to the north-northeast before
dissipating near Spider Island. It may have passed near or over
Spider Island. It also passed through the vicinity of Taylor and
Stonich islands. As of this time, no damage reports have been
received from these islands which do have structures on them, so
the waterspout may have remained over the water. Based on photos
and videos, the waterspout was about 30 yards wide and was on the
water for about 2 miles. No fatalities or injuries have been
reported.
