Canada: Severe weather forecast over parts of east-central British Columbia through Sept. 23
Heavy rain forecast across east-central British Columbia, Canada through Sept. 23. Transport, business, and utility disruptions possible.
Heavy rainfall is forecast across parts of east-central British Columbia through Sept. 23. Heavy downpours, strong winds, lightning, hail, and tornadoes may accompany storms. Environment Canada has issued red rainfall warnings (the highest level on a three-tier scale) for Haida Gwaii and North Coast. Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming hours.
Sustained heavy rainfall could trigger flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed stormwater drainage systems. Sites downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly areas, especially where heavy rain has saturated the soil.
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-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.
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.
