Forest Fire Spreads In Residential Area Near Denver

Denver: A massive wildfire has reportedly reached the edge of metro Denver and crept within a quarter-mile of evacuated homes causing fear of engulfing the residential area. However, the authorities on Thursday stated that they were hopeful that hundreds of threatened residences could be saved as they grappled with sweltering temperatures and firefighters suffering heat exhaustion. The fire was among several threatening heavily populated areas of the Colorado foothills, including one in which a person was killed earlier this week.

Almost 100 large fires are burning across the western US The largest — Northern California's Park Fire — has burned more than 400 houses and other structures, officials reported Thursday. New large fires were reported in Idaho, southeast Montana and north Texas.

5 Firefighters Were Injured 

The Quarry Fire southwest of the Denver suburb of Littleton encroached on several large subdivisions. Neighbourhoods with nearly 600 homes were ordered to evacuate after the fire of unknown origin spread quickly overnight Tuesday.

Five firefighters were injured Wednesday, including four who had heat exhaustion, said Mark Techmeyer with the Jefferson County Sheriff’s Office.

The fire was in steep terrain that made it difficult to access but had been held to less than a half-square mile (1.4 square kilometres) with no houses yet destroyed, authorities said. Officials said it remained a major hazard with hot temperatures and low humidity elevating the fire danger again on Thursday.

“This is not easy folks," Techmeyer said at a press briefing near the fire as heavy equipment rumbled by. “It's 98 degrees (36.7 C). It's hot. They're carrying a ton of equipment that they're wearing and they're doing a very physical job.”

The primary goal of fire crews was to keep flames from crossing over a road on its north end where there are densely packed neighbourhoods.

“If we lose control of that fire and it jumps over the north side, that would be our nightmare,” he said.

Miles to the north near the city of Lyons, Colorado, officials reported making progress on the Stone Canyon Fire that has killed one person and destroyed five houses. The cause is under investigation.

California's arson-caused Park Fire northeast of Chico continued to grow, covering about 610 square miles (1,590 square kilometres) as of Thursday morning. That's more than 25 times the size of New York's Manhattan Island.

Losses also increased. The latest updates tallied 437 structures destroyed and 42 damaged, according to Cal Fire. The fire was 18% contained.

Authorities said they faced critical fire weather in the coming days with potential triple-digit temperatures, thunderstorms and erratic winds. Almost 6,000 personnel were helping battle the Park Fire as more fire crews arrived from Utah and Texas.

Scientists say extreme wildfires are becoming more common and more destructive in the U.S. West and other parts of the world as climate change warms the planet and droughts become more severe.
