CONGRESS, AZ - A wildfire that tripled in size in just hours on Sunday sent thick smoke over parts of northern Arizona much of the afternoon.
ABC15 viewer Matt Oss captured time-lapse footage of the Yarnell Hill Fire burning near the small town of Yarnell around 4 p.m. Sunday.

With a vantage point just off State Route 89 in Congress, Ariz., Oss' footage clearly showed flames creeping over a mountaintop as thick smoke poured into the air.
Officials on Sunday night confirmed 19 Prescott firefighters had been killed in the 6,000-acre blaze, and 250 structures had been lost.
