The ridge of high pressure building over the region Thursday will move east during the weekend, according to the National Weather Service.

"Santa Ana winds are expected to peak Friday midday and then persist, while weakening slightly Friday afternoon through Saturday," according to an NWS advisory. "There could be rapid spread of wildfire that would lead to a threat to life and property."

A small brush fire broke out in the hills above Glendora Wednesday. Aerial units helped knock down the 6-acre fire, which prompted street closures and led to a traffic slowdown on the nearby 210 Freeway.

The city of Los Angeles and Pasadena activated red flag parking conditions Thursday. The restrictions limit parking on narrow and winding roads, allowing fire crews to access the area in the event of a brush fire.

The parking restrictions will be in effect until further notice.

The LAFD pre-deployed resources -- including additonal firefighters and equipment -- Thursday night in high-hazard brush areas.

Temperatures will run 5 to 10 degrees above normal with low to moderate humidity levels. Single-digit humidity will extend from higher elevations to the lower elevations during the weekend.

Wind speeds will average 30 to 40 mph at times, with gusts up to 60 mph along ridgelines and canyons.
