This tornado touched down at 6:15pm, tearing through and destroying a lumberyard and several greenhouses. Trees were also snapped and uprooted along what was described as ‘an obvious path of damage’.
This was one of two tornadoes to touch down in Eastern Ontario on August 4; the other was an F1 at Carp. A third tornado also touched down just east of there at Aylmer, an F3 that damaged and destroyed hundreds of homes through the town.
Figure 1 shows the surface observations at 2:00 pm EDT, which depicts a low pressure on the shores of Georgian Bay with an associated cold front entering eastern Ontario and southern Quebec. This cold front became the focus for intense thunderstorms, which led to several damaging tornadoes across both provinces.
According to Environment and Climate Change Canada (2018), an F1 tornado touched down at 6:15 pm EDT near Alexandria, ON. The track and width of the tornado was not documented by ECCC. The tornado caused no fatalities, injuries or property damage.
