The city of Glendora raised its alert level to Red around 10 p.m. Thursday, prompting more than 1,000 residents in the area to evacuate.

“We recommend evacuations and the evacuations are mandatory. It doesn’t mean we’re going to go into their residences and force them to leave but we’re going to strongly advise that for their safety they should leave their residence. There is nothing they can do,” said Chief Tim Staab of the Glendora Police Department.

An evacuation center was established at the Crowther Teen Center at 241 W. Dawson Avenue.

Officials also said the Inland Valley Humane Society will be available to offer assistance with small animals. If necessary, horses may be taken to the Pomona Fairgrounds, Gate 1.

Police in nearby Azusa also issued evacuation orders Friday morning for 12 residents on the east side of Ridgeview Drive.
