What the reports say
Written by National Weather Service staff at the time of the event · public domain
Main axis of damage is a less than a mile wide path running from 1.3 miles NNW of Rome (near the intersection of White Oak Rd and 208th Street) to 3.2 miles E of Winfield on 120th Street. Between 4 miles Northwest of Mount Pleasant to 2 miles NNE of Mount Pleasant, the damage path widened to 4 miles. Numerous trees and powerlines were downed with severe damage to an ANR pipeline pumping station located northwest of Mount Pleasant. Three homes suffered significant damage…including one which was blown off its foundation while another lost its roof. Numerous outbuildings and sheds were destroyed with grain wagons overturned. The Winfield cemetary (located southeast of town) had its entire 240 foot perimeter fence knocked down with several gravestones damaged. KDVN 88D velocity data suggests severe winds in Jefferson and Louisa Counties from this bow echo, but survey results indicate no damage indicative of severe winds.
The bow echo affected mainly the northern half of the county and crossed the Mississippi into Illinois. The emergency manager reported sporatic damage across the county with mainly trees and power poles down. Based on radar data, the following times have been established (all in CST); Trenton 1102-1112, Swedesburg 1110-1120, Mount Pleasant 1115-1125, Mount Union 1123-1133, Winfield 1127-1136, New London 1128-1136.
