Highway 1 has been shut down between Molera Road and Struve Road, in addition to several local roads. The North Monterey County Unified School District, which services several cities in the area, also announced a closure in response to the fire.

According to county officials, there are some concerns about toxic hydrofluoride fumes being released into the air by the fire and smoke. County and Vistra Corporation officials are observing changes in air quality and will keep residents updated.

The cause of the fire has yet to be determined, and nearly 40% of the building has been destroyed.

This is a developing story; it will be updated.
