Firefighters have stopped the forward progress of the Laguna Fire that broke out Thursday in Ventura County and prompted the evacuation of California State University Channel Island, officials said.

The blaze broke out just before 9 a.m. on agricultural land close to the university in Camarillo and spread to a nearby ridge. Fire crews quickly attacked the blaze from the ground and air to prevent it from spreading beyond 50 acres, officials said.

Andrew Dowd, a spokesperson for the Ventura County Fire Department, credited "aggressive firefighting" for halting the blaze that erupted amid strong winds and single-digit humidity levels across the region.

"Having all these resources available and ready to respond within minutes of this fire breaking out made a huge difference in our ability to bring this under control," Dowd told ABC Los Angeles station KABC.
