Canada: Adverse weather forecast across parts of Alberta, Manitoba, and Saskatchewan provinces through Aug. 1 /update 1

Event

Severe weather is forecast for parts of Alberta, Manitoba, and Saskatchewan provinces through at least Aug. 1. Environment Canada has warned that conditions are favorable for the development of thunderstorms across the affected area; severe thunderstorm warnings are in effect across central Alberta, west central Manitoba, and central Saskatchewan, with severe thunderstorm watches across the rest of the affected area. Officials could update and possibly extend the coverage of weather alerts over the coming hours, including possibly issuing tornado warnings.

Heavy downpours, strong winds, large hail, and possible tornadoes may accompany storms. Heavy rainfall 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 could 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 may 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 could 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.
