Two wildfires burning across the Mountain West region have scorched thousands of acres and forced evacuations as weather conditions Tuesday continue to work against firefighters.

The National Weather Service (NWS) issued a fire weather watch for areas along the California and Nevada borders in the Sierra Nevada mountains and red flag warnings from Arizona and Nevada through Utah into Colorado.

"The fire danger remains high, once again today, with hot temperatures and low humidity for parts of the Desert Southwest and the Great Basin," Fox News senior meteorologist Janice Dean said Tuesday.

The blaze, dubbed the Veyo West fire, started around 3 p.m. in Washington County and was human-caused, according to fire officials.

The western portion of Veyo, located about 20 miles north-northwest of St. George, and the community of Brookside were evacuated initially before orders were lifted. Some evacuations still remain in the area.

Bulldozers and hand crews have been out cutting containment lines to keep the fire from spreading.
