More Orange County evacuations

About 3,000 residents in eastern Orange County were ordered to evacuate their homes as the Santiago Fire was traveling north toward Modjeska and Silverado canyons, about 15 miles east of Irvine, said Christy Romero, a spokeswoman for the Orange County Fire Department.

About 870 homes are threatened in the canyon areas including Williams Canyon, Santiago Canyon at Hangman's Tree, and Joplin Boys Ranch -- all of which are under mandatory evacuation.

The fire has burned through 15,800 acres and is 30% contained, with more than 500 firefighters working the blaze, Romero said.  She said two helicopters were dropping water this morning.  No structures have been damaged, she said.

Four firefighters suffered minor injuries Monday, Romero said.
