A tornado warning has been issued in northwestern Ontario as a severe thunderstorm capable of producing a tornado has been detected on radar, according to Environment and Climate Change Canada (ECCC). In addition to potentially producing a tornado and intense winds, large hail and locally intense rainfall are possible. See below for the details.

4:40 PM CDT: Environment Canada meteorologists are tracking a severe thunderstorm that is possibly producing a tornado. Damaging winds, large hail and locally intense rainfall are also possible.

4:32 PM CDT: Environment Canada meteorologists are tracking a severe thunderstorm that is possibly producing a tornado. Damaging winds, large hail and locally intense rainfall are also possible.

A severe thunderstorm capable of producing a tornado is located six kilometres west of Cobble Lake, moving northeast at 30 km/h.

Hazard: Tornado and 90 km/h wind gusts.

Locations impacted include: Blue Lake Provincial Park, Big Canon Lake, Canyon Lake, Segise Lake, Cobble Lake, Forest Lake, McIntosh, Whitney Lake, Edward Lake and Indian Lake.

This is a dangerous and potentially life-threatening situation.

Take cover immediately, if threatening weather approaches. If you hear a roaring sound or see a funnel cloud, swirling debris near the ground, flying debris, or any threatening weather approaching, take shelter immediately.

The tail end of Monday's storms in Manitoba has developed another line of severe storms in northwestern Ontario on Tuesday. Lake of the Woods and Dryden will be at the southern end of the risk, thanks to storms remaining well north of Thunder Bay and the majority of Highway 17.

Aside from the tornado warning and severe storms, there is a rainfall warning in place for Ear Falls - Perrault Falls - Western Lac Seul. Totals of 50-80 mm are expected with the slow-moving storms in the Kenora and Red Lake region.

The same area will see storm potential again on Wednesday and Thursday as the developing Prairie system nears.
