...NWS Damage Survey for 06/12/2024 Tornado Event...

.Update #2...

Updated to adjust the end point of the path of the Wolford to
Rabbit Lake to Cedar Lake to Prescott Lake Tornado, add a new
tornado from Hammal Lake to Hanging Kettle Lake to Ripple Lake,
add a new tornado northeast of Isabella within the Superior
National Forest, and clarify the tornado narratives.

.Overview...

Numerous severe thunderstorms moved across north-central and
northeast Minnesota on the evening of Wednesday, June 12, 2024,
producing large hail to the size of baseballs, isolated
thunderstorm wind damage, and several tornadoes. Two distinct
supercellular storms produced five tornadoes (rated EF-0 and EF-2)
across portions of Crow Wing, Aitkin, and Carlton counties
between roughly 6:15 PM and 7:30 PM. The supercell that tracked
through Crow Wing and Aitkin County produced four separate
tornadoes, first on/near Upper Whitefish Lake across to Clamshell
Lake, or west of Crosslake, where a wide, sharp path of damage was
found. This tornado dissipated, with a second tornado forming
south of Wolford, west of Rabbit Lake (north of Crosby). This
second tornado appeared to have a mainly continuous path of damage
from near Wolford to Rabbit Lake to Cedar Lake to Prescott Lake.
There may have been a break in this tornado as it traveled across
the Crow Wing State Forest, but a combination of storm chaser and
spotter video as well as ground surveys seemed to indicate a
mainly consistent path of damage. A third tornado near the
northern portion of Hammal Lake and continued east-southeast
through Hanging Kettle Lake and Ripple Lake, where it destroyed a
three-season cabin and boat house, toppled an 85 foot tall antenna
tower, and uprooted and snapped numerous trees. This supercell
then later produced a weak, wispy tornado with no known damage
near Glen, MN, with the particular length of this tornado unknown
due to Limited access in this area. While this supercell was
ongoing, a Separate supercell briefly produced a weak tornado in
northwest Carlton County where mainly minor tree damage (large
branches, a few trees snapped) was observed north of Wright, MN.
No injuries or fatalities were reported, and NWS Duluth had a
Tornado Warning in effect for these storms for the duration of
time they produced tornadoes.

Another supercell thunderstorm tracked across northeast St. Louis,
northern Lake, and extreme southern Cook counties. NWS Duluth has
not received reports of damage from that storm as of this
afternoon and a survey team did not find damage along the North
Shore on Thursday. We continue to look for information about this
storm and any potential hail or wind damage it may have produced.

This information is preliminary in nature and will likely be
revised as we continue to review additional reports, images, and
videos. NWS Duluth sincerely appreciates the coordination with our
state and local partners including Emergency Management and
Sheriff Departments at Carlton, Aitkin, and Crow Wing Counties as
well as the Minnesota State Patrol. We also sincerely appreciate
the images and video shared with us by our local media partners.

The listing below is ordered by storm and then by time of the
tornadoes.

southeast Norman County, west of Wabun. The storm tracked

Survey Summary:
A tornado redeveloped near Wolford, from the same storm that
produced the first tornado near Crosslake. Initial damage located
along County Road 30, south of County Highway 11/Mississippi
River, mostly trees snapped and uprooted. Tornado continued east-
southeast across Rabbit Lake just north of Cuyuna and then towards
Highway 210. Damage along the western shore of Rabbit Lake
affected private residences with a RV flipped over, roof covering
material partially removed, and numerous trees snapped which lead
to secondary home damage, including several collapsed out-
buildings and garages. The tornado crossed Highway 210 near mile
marker 145, as evidenced by both tree damage and storm chaser
footage. It then took a southeastward path across portions of
western Cedar Lake, producing extensive tree damage and pockets of
residential property damage to roofs and garages, including a fish
house that was picked up and thrown nearly 100 yards. This is the
area of low-end EF-2 damage. The tornado path then continued southeast,
crossing 456th Place, 320th Street, and, finally, 310th Street before
lifting. This last section of the tornado path after Cedar Lake shows
damage to numerous trees via satellite imagery before the visible
damage path ends just to the southwest of the intersection of 310th
Street and Pioneer Avenue. No fatalities or injuries were reported.

Cromwell. Minor tree damage was noted on West Road near the start
of the tornado path, with a broad area of large branches down and
a few trees snapped towards the top. The tornado then traveled
across a mainly marsh/bog landscape, crossing Center Road where
power lines were damaged and widespread tree damage was noted
along a 50 yard stretch of road. The tornado track continued on a
southeast to east-southeast path, with the last signs of damage
near to just south of Highway 210 near Woodbury Lake where a few
clusters of tree damage were noted. No injuries or fatalities were
reported, and property damage was very limited, with only a
handful of homes/buildings impacted.

This storm was the earliest supercell of the severe storm event,
initially developing in Koochiching into far northern Saint Louis
County where it split. The right split headed for Ely, MN and
continued on a southeast path towards Tofte. The supercell was
rotating throughout its lifetime, with a report of a funnel cloud
when the storm was east of Ely. The storm briefly weakened for a
time, then strengthened and produced strong mid-level rotation
northeast of Isabella.

Survey Summary:
Tornado damage initially appeared on the northeast shore of Tanner
Lake (east of Dumbbell Lake), crossing Wanless Road (Forest Road
172) on a southeastward track. Satellite imagery depicts sporadic
tree damage along the path, with a particularly impressive swath
of trees that were uprooted or snapped east of East General Grade
Road (Forest Road 362) measuring approximately 150 yards in width
and a quarter mile in length. Damage continues to be evident for
another mile or so before no additional discernible damage is
evident. No fatalities or injuries were reported. Tornado rating
was determined based on satellite imagery, and NWS Duluth is
coordinating to learn more about any air or ground surveyed damage
from our partners at the Superior National Forest which may result
in a future revision in the tornado rating.
