A pair of fires have forced evacuations in Riverside County, officials confirmed. Cal Fire said that the two blazes, dubbed the Dale Fire and Bradford Fire, are spanning more than 330 acres in the Lake Riverside area in Aguanga. Crews were battling the pair of fires as one, officials said.

Dale Fire initially started 12:37 p.m. July 16 in Riverside County, California. It has burned 1,071.6 acres after being active for 14 hours. A fire crew of 358 has been working on site and they managed to contain 10% of the fire by Thursday morning. The cause is, however, still being investigated.

A brush fire ignited in the foothills of the Palomar Mountains in Riverside County on Wednesday afternoon, quickly growing to 331 acres and prompting evacuation orders in nearby rural communities, authorities said.
