FORECAST DISCUSSION
Keep an eye out for the potential development of pop-up thunderstorms in Extreme Eastern Ontario, specifically around the Ottawa Valley, during the mid to late afternoon hours on Tuesday. While there is a chance that a few of these storms may become marginally severe, it's important to note that the risk is quite uncertain due to the possibility of limited storm development in the area.
Should these storms materialize, they could bring threats such as up to quarter-sized hail, wind gusts reaching 90 km/h, and localized flash flooding. While the risk is not definite, we believe it's significant enough to warrant an isolated severe risk zone, which includes areas like Ottawa, Smiths Falls, and Cornwall.
The tornado risk remains very low, but it's important to remember that tornadoes can never be completely ruled out.
