Canada: Adverse weather forecast in parts of southeastern Ontario and southwestern Quebec through late July 13
Severe thunderstorms forecast across parts of Ontario and Quebec, Canada, July 13. Possible transport, business, and utility disruptions.
Event
Severe weather is forecast over parts of southeastern Ontario and southwestern Quebec July 13. Severe thunderstorms are expected across the region during the afternoon and evening; heavy downpours, strong winds, large hail, and possible tornadoes may accompany storms. Environment Canada has issued a tornado watch for parts of far southeastern Ontario, including Ottawa and Kingston. Severe thunderstorm watches are in place across southwestern Quebec, and a special weather statement for heavy rainfall has been issued for parts of southwestern Ontario. Officials could update and possibly extend the coverage of weather alerts over the coming hours, including possibly issuing tornado warnings. Heavy downpours could trigger flooding in low-lying areas, and strong winds could cause property damage and power outages. Authorities have warned people in the affected area to take cover if threatening weather approaches.
The severe weather will likely contribute to transport disruptions throughout the region. Floodwaters and debris flows may render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters.
Severe weather will likely trigger flight delays and cancellations at airports across the affected region. Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas with heavy rainfall and potential track inundation.
Localized business disruptions will likely occur in flood- or tornado-hit areas; some businesses might not operate at full capacity because of damage to facilities, possible evacuations, and some employees' inability to reach work sites. Strong winds could also cause power outages.
Advice
Monitor local media for updated emergency and weather information. Seek updated information on weather and road conditions before driving or routing shipments through areas where severe weather is forecast. Plan accordingly for potential delivery delays if routing shipments by truck through the affected area. Do not attempt to drive through flooded areas. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
