Figure 1 depicts the surface observations at 4:00 pm CDT, which shows an occluding low pressure system over central Manitoba with a sharp cold front extending south across southern Manitoba and a warm front extending east across northern Ontario. The cold front became the focus for thunderstorms in the afternoon hours of June 23rd, which ultimately led to this tornado.
According to Environment and Climate Change Canada (2018), an F0 tornado touched down at 5:15 pm CDT near Lac du Bonnet, MB. The path of the tornado was not documented by ECCC, but its maximum width was 30 metres. The tornado caused no fatalities, injuries or documented property damage.
