mandatory evacuations

Mill Creek Canyon on Tuesday.

Fears of post-fire erosion resulted in mandatory evacuation orders just before 2 a.m. today in vulnerable Yorba Linda neighborhoods, as heavy rains continued pounding the Freeway Complex Fire burned areas.

From the city's web site:

MANDATORY EVACUATIONS ORDERED

"Mandatory evacuations are in effect for the Brush Canyon Area, the Box Canyon Area, and the North Fairmont/San Antonio area. During the mandatory evacuation, the Thomas Lasorda, Jr. Field House (4701 Casa Loma Avenue) will be available as a shelter location."

The Weather Service updated flash flood warnings at 12:40 a.m. and 12:52 a.m. today for the Freeway Complex Fire burned area, in effect until at least 3:45 a.m.
