No damage was caused by this tornado. Witnesses photographed a funnel cloud extending to the ground but with its base obscured by trees. Figure 1 depicts the surface observations at 2:00 pm EDT, which shows an occluding low pressure system in central Ontario. This low pressure caused enough convergence and vertical motion to initiate thunderstorms around the Sudbury area, which ultimately led to this weak tornado.
According to Environment and Climate Change Canada (2018), an F0 tornado touched down at 4:00 pm near Estaire, ON. The path and width of the tornado was not documented by ECCC. The tornado caused no fatalities, injuries or property damage.
