Rain in forecast for holiday

Mostly sunny skies should prevail through Saturday, when clouds will start to build to create a chance of rain and thunderstorms overnight.

On Sunday, there will be a 30% chance of rain, according to the National Weather Service, which could spell more trouble for hillsides that reached their saturation point earlier this week when a powerful series of storms soaked the area.

Officials have warned that even under sunny conditions, the hillsides remain vulnerable to movement, and advised property owners to be vigilant.

Los Angeles County public works officials on Thursday announced plans to begin excavating and clearing out the Mullally debris basin above La Cañada Flintridge on Monday, a one-week process that will see increased heavy truck traffic along the route, officials warned.

The process could take longer depending on weather conditions.
