FORECAST DISCUSSION

There is a chance of isolated severe storms during the afternoon on Wednesday along the International border in Extreme Southeastern Manitoba, located to the south of Winnipeg. However, there is some uncertainty regarding the exact location of storm development, and it's possible that they may form south of the border, posing no threat to Manitoba.

If these storms do develop within the region, they could bring the following threats:

  • Damaging Wind Gusts: Expect wind gusts reaching speeds of up to 90 km/h, which can cause tree damage and power outages.

  • Large Hail: There is a potential for hail up to the size of toonies, which can cause damage to vehicles and property.

  • Flash Flooding: Localized heavy rainfall may lead to flash flooding in certain areas.

Additionally, there is a slight chance of funnel clouds, which in rare cases, can touch down and become landspout tornadoes.
