Tornado warnings in northwestern Ontario as severe storms roll in

Tornado warnings have been issued for the Atikokan-Upsala-Quetico and Fort Frances-Rainy Lake areas in northwestern Ontario. Take cover now if you find yourself in the affected areas.

Tornado watches are in effect for the above area and other areas of Northwestern Ontario as there is a threat of severe thunderstorms capable of producing tornadoes, torrential rains and hail – from a penny the size of a ping pong ball – in the area until Monday evening. Conditions are favorable for the development of severe thunderstorms, which can produce tornadoes and damaging wind gusts up to 130 km/h. There is also a risk of severe thunderstorms in southern Manitoba on Monday.

CURRENT TORNADO WARNINGS

9:03 p.m. EDT – Environment Canada meteorologists are monitoring a severe thunderstorm that may produce a tornado. Damaging winds, large hail and locally intense precipitation are also possible.

A severe thunderstorm capable of producing a tornado is located 40 kilometers southwest of Sand Point Lake, moving northeast at 85 km/h.

Hazards: Tornado, wind gusts to 100 km/h and hail the size of a nickel.

Source: Rotation indicated by the radar.

Affected locations include Sand Point Lake and Lac la Croix.

This is a dangerous and potentially fatal situation. Take cover immediately if threatening weather approaches. If you hear a rumble or see a funnel cloud, swirling debris near the ground, flying debris, or other threatening weather approaching, seek shelter immediately.

  • Atikokan-Shebandowan-Quetico Park

  • Upsala-Raith

  • Fort Frances-Emo-Rainy River

  • Seine River Village-Mine Center

4:32 p.m. (EDT) – A line of dangerous thunderstorms is expected to move into northwestern Ontario early this evening, persist through the evening and weaken overnight. The main threats are wind gusts of up to 130 km/h and tornadoes.

Any tornadoes that form will move quickly and will likely be shrouded in rain, making them difficult to see.

This is a dangerous and potentially fatal situation.

A tornado watch does not mean that a tornado has been spotted, however, it is issued when atmospheric conditions are favorable for the development of thunderstorms capable of producing tornadoes.

Residents are urged to closely monitor the forecast and prepare to seek shelter immediately in the event of inclement weather.

MONDAY TO TUESDAY: RETURN OF THE THREAT OF SEVERE WEATHER, POSSIBLE TURNING THUNDERSTORMS

The unstable pattern that brought rains and thunderstorms continues, with another stronger system bringing widespread rains and thunderstorms Monday afternoon through Tuesday morning.

“Thunderstorms will become more widespread in southeastern Manitoba and northwestern Ontario as a gust is expected to move in later Monday evening,” said Matt Grinter, Meteorologist at The Weather Network. “These storms will continue into the early hours of the night and this is the time when there is a risk of one or two tornadoes.”

Other possible hazards with any storm that reaches severe criteria include large hail, strong wind gusts, and heavy rain. For southern Manitoba, the threat of more downpours is a major concern for areas trying to recover from recent flooding.

FLOOD WARNINGS ON LAND AMID HEAVY RAIN TOWERS

Special weather reports cover the area, warning of heavy rainfall expected through Tuesday. General rainfall amounts of 30-50mm are expected, although the precise amounts depend on the development of thunderstorms on both sides of the international border. Heavy showers with locally higher precipitation totals are possible.

“Heavy downpours can cause flash flooding and pooling of water on roads,” Environment and Climate Change Canada (ECCC) says in the special weather statement. “Be aware of possible washouts near rivers, streams and culverts.”

This will lead to greater delays in spring planting, which is already a few weeks late. May 31 is a critical deadline for many farmers to decide whether they will try to move forward with the season or take advantage of crop insurance.

A surface flood warning has been issued for the southeast corner of Manitoba, as announced in a provincial flood bulletin on Sunday.

According to the bulletin, water levels in lakes and streams are already high and soils are saturated with water, so rain expected to hit the province through Tuesday could lead to overland flooding.

In western Manitoba, wind warnings are in effect, with gusts of up to 90 km/h forecast through Tuesday morning. Winds will decrease Tuesday afternoon as the low continues to move east across northwestern Ontario.

“Damage to buildings, such as roof shingles and windows, may occur,” ECCC says in the warning. “Loose objects can be blown around and cause injury or damage. High winds can lead to power outages and fallen tree branches.”

Winds can also raise water levels along the shoreline, adding a temporary increase in water levels in Lake Winnipeg, Lake Manitoba, Lake Winnipegosis and Lake Dauphin.

LOOK AHEAD: COOLER WEATHER AND INSTABILITY ON THE ROAD

Much cooler weather will spread across the region in the first half of this week, with temperatures 5-10 degrees lower than seasonal.

While the eastern Prairies are expected to receive large amounts of rain in the coming days, it will be a different story for the western sections.

A disappointing forecast for southern Alberta farmers over the next week as widespread rains will remain south of the border. With just scattered showers, most will miss the much-needed driving rain.

Model data shows a rather favorable pattern for beneficial rains for the second week of June, but we’ve seen a lot of false hope turn into dry forecasts, so it’s just something we’ll continue to watch closely for the moment.
