Figure 1 shows the surface observations at 7:00 am CDT, which shows a low pressure system in northern Manitoba with its associated occluded front extending south. A cold front is observed extending south across southern Manitoba and into the High Plains of the United States and a warm front across northwestern Ontario. The low began its occlusion stage across Manitoba during the day of July 16th. As it did so, the cold front began moving east-northeast and triggered thunderstorms across southeastern Manitoba, which ultimately led to this tornado.
This tornado was part of a tornado outbreak that occurred across southeastern Manitoba on this day:
- Emerson, MB F0 Tornado
- Melita, MB F0 Tornado
- St. Alphonse, MB F0 Tornado
- Near Portage La Prairie, MB F0 Tornado
- Graysville, MB F0 Tornado
According to Environment and Climate Change Canada (2018), an F0 tornado touched down at 7:30 pm CDT near Hadashville, MB. The track and width of this tornado was not documented by ECCC. The tornado caused no injuries, fatalities or property damage.
