Tornado in ITASCA, MINNESOTA
From 19-JUN-16 17:50:00 to 19-JUN-16 17:59:00 (CST-6)
Location: SWAN RIVER
Tornado F-scale: EF1
Reported by: NWS Storm Survey

The tornado developed in a wooded area and bog in far northern Aitkin County, about 1.25 miles north-northeast of the intersection of Highways 65 and 200. The tornado tracked northeast and continued into Itasca County. The tornado moved through far southeast Itasca County, crossing US Highway 2 and dissipating near a grove of trees approximately 1 mile west of the St. Louis County line. The tornado destroyed several pole barns, lofted a roof from a house, and destroyed the house. Analysis of the construction methods at this location, and surrounding damage, yielded a rating of EF-0. However, EF-1 tree damage was noted immediately west and north of Sabo 2 and continued eastward. The tornado reached its maximum intensity approximately 2.2 miles southwest of Wawina where high-end EF-1 damage was noted to a stand of trees. Oblique angle aerial photography from the western end of the track revealed a path through the bog adjacent to US-2, which was not directly observable from the air nor from the ground. The tornado moved through two small stands of trees breaking branches and snapping a few narrow trunks before dissipating. Several videos and photographs of this tornado have been reported.

Tornado F-scale: EF1
Reported by: NWS Storm Survey

The tornado developed east of the Burlington Northern Santa Fe railroad near the St. Louis River and tracked east-northeast for approximately 3.1 miles while producing sporadic pockets of low-end EF1 damage to softwood trees. The tornado struck a house which resulted in partial uplift of the roof and lofting of roofing materials. The tornado also flattened a decorative windmill and bent a flagpole. The roofing material was distributed downwind to a range of 380 yards. The tornado also snapped and uprooted several trees in this vicinity. The damage at this location was also rated EF-1. The sporadic damage track continued for another mile to the east-northeast. There was a distinct weakening of the tornado with several pockets of broken branches and limbs noted approximately 3 miles southwest of Zim. The tornado then turned southeast and the damage track tightened once again with a wide swath of EF-0 tree damage and pockets of low-end EF-1 damage. The sporadic EF-1 damage continued as the tornado crossed MN-7 and dissipated southwest of Stone Lake.
