About three firefighters and two people were injured in fires across Utah.
Authorities said there are at least 388 fires which burnt some 270,000 acres of state land.
The largest fire is at Cottonwood, which has burnt more than 144 square miles, southwest of Utah.
Three big fires began around the 19th of June.
Professor Philip Dennison, chair of the University of Utah’s School of Environment, Society & Sustainability, is a leading expert in remote sensing and wildfire science.
Dennison said “the big thing these fires have in common is that drought and high temperatures have made vegetation very susceptible to burning this summer. When combined with high winds and an ignition, fires can grow very rapidly. Most of the fires we’ve seen so far this year fit a common pattern—human activity causes an ignition in dry grass and under high winds, the fire quickly gets carried by grasses and sagebrush uphill through areas of denser fuels.”
