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

Crews hope wet weather could be turning point' after worst start to fire season on record in which area the size of Wales has burned

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.
