RIVERSIDE, Calif. (AP) — Crews are currently battling a rapidly spreading wildfire in Riverside County, which has forced some residents to evacuate and resulted in the temporary closure of Moreno Valley College.

The Springs Fire ignited around 11 a.m. Friday and has since expanded to cover approximately 6.5 square miles (16.8 square kilometers). The cause of the blaze is still under investigation, and the number of homes affected by evacuation orders has yet to be confirmed.

Firefighting resources have mobilized hundreds of personnel, including helicopters, fire engines, and water tenders, to combat the flames. By Friday night, efforts to contain the fire were underway.

Located east of Moreno Valley, the fire is encroaching upon a sparsely populated but recreational area. Moreno Valley itself is situated about 10 miles southeast of Riverside and has a population nearing 200,000.

Maggie Cline De La Rosa, a public information officer with the California Department of Forestry and Fire Protection, noted the challenges posed by the windy conditions.

As the fire rages, Alex Izaguirre, a spokesperson for Cal Fire Riverside County, mentioned that smoke is becoming a growing concern, prompting calls from residents in neighboring areas who are experiencing the effects.

The main campus of Moreno Valley College temporarily closed due to the poor air quality resulting from the fire, with the administration urging all students, faculty, and staff to evacuate the premises.

California Representative Raul Ruiz urged those under evacuation orders to leave immediately, as officials continue to monitor the situation closely. The National Weather Service has issued a wind advisory for San Bernardino and Riverside County, predicting gusts reaching up to 50 mph.

As the situation develops, authorities will provide further updates, and residents are advised to stay vigilant.
