Tornadoes

Tornado - Voyageurs National Park Locator Lake to Marion Bay (Rainy Lake) St Louis County, MN Date 7/17/2019 Time (Local) 7:49pm - 8:06pm CDT EF Rating EF-1 Est. Peak Winds 100 mph Path Length 3.5 miles Max Width 600 yards Injuries/Deaths None Summary: A damage survey of a tornado within Voyageurs National Park has been completed and confirmed a tornado from approximately Locator Lake, approximately 7.3 miles north of Kabetogama, to Marion Bay on Rainy Lake, approximately 9.5 miles west-northwest of Kabetogama. The tornado likely extended farther northeast across Rainy Lake and possibly into Canada, so the length of this tornado should be considered an estimate. The end point location is estimated from video of the tornado moving over Rainy Lake. This survey was completed using photos and videos from Voyageurs National Park, the public, and business owners in the region. Very special thanks to Voyageurs National Park for sharing aerial images of the damage path which was critical to assessing the path, width, and severity of this tornado.

Tornado - Gheen Hill, MN St. Louis County, MN Date 7/17/2019 Time (Local) 8:01 PM - 8:16 PM CDT EF Rating EF-1 Est. Peak Winds 90-95 mph Path Length 5.75 mi Max Width 420 yards Injuries/Deaths None Summary: The supercell which produced the Gheen Hill tornado began north of Togo in far southeast Koochiching County. It traveled toward the east-northeast and gradually organized. Sporadic straight-line wind damage was observed a few miles northwest of Gheen and west of US Highway 53. The tornado developed 1 mile west of US-53 and tracked toward the east-northeast. We received several photographs from a spotter who observed the tornado north of Gheen Hill before it crossed US-53. The tornado crossed Rice Lake and strengthened to low-end EF-1 intensity shortly after. The tornado continued east-northeastward across the easternmost portion of Johnson Road. It weakened and dissipated just to the east of an ATV trail northwest of Gheen. Aside from the few spotter photos of this tornado, high-resolution satellite imagery was critical to assessing the location, path, width, and peak intensity of this tornado. We are very grateful to the spotter who provided the only known photos of this tornado. Additional help in identifying this tornado's path was provided by a private sector meteorologist from Grand Rapids, MN. This supercell thunderstorm would go on to produce the Carlson Lake tornado.

Tornado - Carlson Lake, MN St. Louis County, MN Date 7/17/2019 Time (Local) 8:23 PM - 8:37 PM CDT EF Rating EF-1 Est. Peak Winds 100-105 mph Path Length 5.8 mi Max Width 500 yards Injuries/Deaths None Summary: The supercell which produced the Gheen Hill tornado continued to move toward the east-northeast and a second mesocyclone developed a short time after the Gheen Hill tornado dissipated. The Carlson Lake tornado developed approximately 500 yards west of the Elbow River and six-tenths of a mile north of the western end of Ban Lake. The tornado tracked toward the northeast producing sporadic EF-0 damage to trees. The tornado turned due east approximately one mile west of Carlson Lake and intensified. The tornado produceda swath of EF-1 damage, which was a maximum of 300 yards wide and passed over Carlson Lake. Tree damage corresponding to high-end EF-1 wind speeds was noted over much of this area. The tornado turned toward the northeast after crossing Carlson Lake and crossed over Elbow Lake Forest Road before gradually weakening. The tornado dissipated shortly after crossing Shuster Road. We are very grateful for the help identifying this tornado's path provided by a private sector meteorologist in Grand Rapids, MN. High-resolution satellite imagery was critical to assessing the location, path, width, and peak intensity of this tornado. Track Map   Downloadable KMZ File
