PORTER RANCH, Calif. (KABC) — Southern Californians are bracing for the return of the Santa Ana winds, which could mean an increased risk of wildfires as well as flying tree limbs and power lines.

And the fact that they arrive so close to Halloween poses further dangers for some homeowners.

Arnie Padilla of Burbank still has an elaborate exhibit honoring Alice in Wonderland in his home. But the wind makes him nervous. Not only could they send his display flying around the neighborhood, but he also knows there's a danger from electrical sparks.

“I have to stay up all night checking,” Padilla said. “Every second I hear the wind in the window blowing just a little whistle, I think, OK, come out and take a look.”

Firefighters say the wind makes even the smallest spark dangerous.

“We're looking at 55 to 85 miles (per hour) in the mountains with just sustained gusts and winds, and in the valleys we're looking at 35 to 55,” said Capt. Sheila Kelliher of Los Angeles County Fire.

Kelliher advises residents to stay away from activities that could be dangerous in such strong winds.

“If you're gardening or cutting the grass, wait until the wind stops,” Kelliher said. “Wait until you have a better chance of not starting a fire.”
