Heat warning after fatal wildfire
Forecasters are warning of critical fire conditions as crews battle a wildfire that has scorched more than 4.5 square miles in central Oklahoma.
The US National Weather Service has issued a red flag warning for western and central Oklahoma, and forecasters say temperatures could pass 38C with low humidity and gusts up to 45mph.
Guthrie fire chief Eric Harlow said firefighters have contained about 90% of the blaze after winds died down in the city about 35 miles north of Oklahoma City.
He added that the wildfire has destroyed at least 10 homes and left one person dead.
Forecasters say parts of Arizona, Colorado, Kansas, Texas, New Mexico and Utah are also at a high risk of wildfires.
