Heavy rains in Canada offer relief from wildfires but could lead to flooding

Heavy rains have brought relief to western Canada, in what crews hope could be a “turning point” in a protracted fight against wildfires, but officials also warned the much-needed downpour could lead to catastrophic flooding – and fresh blazes from lightning strikes.

Officials in Alberta said that cool, wet weather over the weekend – and more forecast for the coming days – promised a respite after the worst start to a fire season on record, in which 512 wildfires have already consumed more than 945,000 hectares – surpassing the previous record 615,00 hectares for the same period in 2019.
