Four wildfires burning in western Colorado have consumed more than 250 square miles, threatened hundreds of homes and forced evacuations, fire officials said.

Spain's worst wave of wildfires on record spread to the southern slopes of the Picos de Europa mountains and prompted authorities to close part of the popular Camino de Santiago pilgrimage route.

Spain and Portugal were the worst-affected countries in Europe, which has seen its most destructive wildfire season in nearly 20 years.

The fires have ravaged small, sparsely populated towns in the country's northwest, forcing locals in many cases to act as firefighters. About 2,382 square miles have burned across Spain and Portugal.

By Nacho Doce and Guillermo Martinez GONDULFES, Spain (Reuters) -Wildfires raging in northern and western Spain have burned through nearly the same area in the past 24 hours as in all of last year, although the end of a 16-day heatwave and expected rainfall have fanned hopes that an end may be in sight.

The death toll is now at two in Portugal and four in Spain as the fires burn for a second week, according to AFP. The fires are largely located in the northwest regions of Galicia, Castile and León, and Extremadura. More than 31,000 residents have been evacuated from their homes in Spain due to the fires, according to The Guardian .

Spain's weather agency warned the public on Monday to be "cautious" of the "very high or extreme fire danger."

Canada's second-worst wildfire season on record has already burned 7.8 million hectares and could continue for weeks, federal government officials said Monday.

The study comes as Trump has issued an executive order calling for more logging on federal land to boost timber production and mitigate fire risk. The study instead suggests prescribed burns are the best tactic – a practice that has been historically used by indigenous people before land agencies stopped them in the 1900s.
