Tornado - REMER/HILL CITY, MN Cass/Aitkin, MN Date August 29, 2013 Time (Local) 6:28 PM to 6:55PM CDT EF Rating EF-1 Est. Peak Winds 90-100 MPH Path Length 12.8 Max Width Approx. 300 yards Injuries/Deaths 0 Summary: Sporadic tree damage, including some broken birch and evergreen trees, was observed along the entire path of the parent storm, beginning near the northern end of Leech Lake northwest of Federal Dam. The damage appeared to concentrate and become convergent northwest of the intersection of County Road 4 NE and County Road 52 NE to the northwest of Remer, indicating the start of broad and weak tornado track at approximately 6:28 PM. The tornado then produced sporadic but concentrated and convergent damage from that location to the northwestern end of the Remer Municipal Airport, to Minnesota Highway 6 on the southeast corner of Mud Lake, to the northern end of Birch Lake. From there the track became more narrow and the damage more intense and nearly continuous crossing East Boundary Road NE to the northwest of Sailor Lake. From there the tornado continued east-southeast eventually turning more southeasterly south of Holy Water Lake and eventually crossing Minnesota Highway 200 west of the Little Hill River about 5 miles west of Hill City. The tornado dissipated shortly after crossing Highway 200 at approximately 6:55 PM. The parent supercell thunderstorm continued to produce sporadic and divergent wind damage southeast of the end of the tornado track for another 7 miles to near Haypoint. Additional information and notes about damage in northeastern Cass and Northwestern Aitkin County: -This is the first recorded tornado in Cass or Aitkin Counties since the June 17, 2010, outbreak. -A house north of Remer was damaged when several trees fell onto it. Otherwise, property damage was limited to small structures and trees. -Sporadic wind damage was observed west-northwest of the tornado track in Cass County. This damage featured a slightly divergent windflow pattern, which suggest non-tornadic "straight line" winds of 50 to 65 MPH were the culprit. Start location: 1.7 miles NNW Remer (LAT 47.079, LON -93.928) End location: 5.0 miles WSW Hill City (LAT 47.982, LON -93.702) Track Map (Figure 3) Track Map Including Wind and Hail Damage (Figure 2) Overall Survey Area (Figure 1)
