(KGTV) - A massive fire continues to burn in Ventura County Tuesday, destroying 150 structures and forcing tens of thousands of residents to flee from their homes.
The so-called Thomas Fire erupted at about 6 p.m. Monday in the Santa Paula area . Aided by strong and dry Santa Ana winds, the blaze burned 10,000 acres by 11 p.m.
Crews were unable to use air drops on the fire because it was night and the strong wind conditions. Authorities said they would fight the fire by air at first light Tuesday.
Cal Fire San Diego officials confirmed they sent five fire engines and a bulldozer to assist crews in Ventura.
As of 8 a.m. Tuesday, the fire has burned 45,000 acres with zero containment.

Students at Thomas Aquinas College, a private Catholic college in Santa Paula, were evacuated Monday night, the school tweeted. The college, Santa Paula and Ventura Unified School Districts announced their Tuesday closures, CNN reported.
Evacuation information and road closures are being updated on the ReadyVenturaCounty website .
The fire also took down power lines, causing power outages that left tens of thousands of customers in Ventura and Santa Barbara counties without service, according to utility company Southern California Edison.
Ventura County Fire officials said they "expect fire behavior to increase over the entire incident" due to increased wind activity Tuesday.
