A voluntary evacuation for the burn area was ordered at 8 a.m. Tuesday and affects all homes east of 30311 Silverado Canyon Rd., where the Silverado Fire scorched approximately 1,000 acres in September. There's not enough vegetation on the steep hillsides to hold back water.

Sandbags for canyon residents are available at the Orange County Fire Authority's Station 14, 29402 Silverado Canyon Road, as well as at an Orange County Public Works' Maintenance Yard, 20811 El Toro Road in Lake Forest.

The Red Cross opened a shelter at El Modena High School at 3920 East Spring Street in the city of Orange.

Hay bales and K-rails are in place to prevent mud flows and property damage, and heavy equipment is on scene ready to move debris.

A steady downpour was falling over Silverado Canyon burn area since around 7 a.m. Nearly an inch of rain had fallen by about 7 p.m.

Emergency crews are on standby and many residents say they're braced and ready.

"My wife has already evacuated with pets. So when mandatory comes in, I'm out of here," said area resident Ron Shepston.

Shepston lives at the base of a steep, narrow and sloping road. He and his neighbors have been scurrying to prepare for the worst.
