Storm threat grows in southern Manitoba, NW Ont., after confirmed tornado Sunday
Southern Manitoba is in line for another round of storms Monday, with an increased chance of tornadoes
A volatile storm system is once again threatening southern Manitoba today, with forecasters warning that the risk of tornadoes is greater than during Sunday's round of severe weather.
The concern comes after a confirmed tornado in the region the day before and the same system is continuing to move in warm, unstable air. A strengthening jet stream is also expected to provide additional energy to developing thunderstorms throughout the afternoon.
Communities along and south of Highway 1 remain in the highest risk zone, though Winnipeg may see severe storms later in the day as conditions improve for rapid storm development.

Peak risk expected late afternoon into evening
The most active period is projected between 4 p.m. and 9 p.m. CT, when storms may intensify and rotate.
Large hail, damaging winds and heavy rainfall are all a possibility, but the main concern is tornado development, particularly in extreme southern Manitoba near the Ontario border.
While forecasters are confident that multiple thunderstorms will form, they warn that exact storm tracks and timing are unknown, determining which communities will suffer the most damage.
Storm threat continues into northwestern Ontario

The system is expected to move east into northwestern Ontario Monday night, bringing more severe weather into the evening hours.
Storms may continue to rotate between 6 p.m. and 10 p.m. CT, particularly south of Highway 11, with some risk extending as far as Highway 17 along Lake Superior's western edge.
Following a confirmed tornado on Sunday, forecasters believe Monday's setup could be even more favourable for severe and potentially tornado-like storms, depending on how the system evolves.
