A weak weather system is bringing snow to the mountains and rain to other parts of Southern California.
Rainfall rates are not expected to match those of the Jan. 9 storm that caused flooding and damaging mudflows throughout the region and unleashed devastation in the Santa Barbara County coastal community of Montecito. At least 20 people were killed, and the search continues for three missing people.
Crews plan to work through the weekend to clear mud and debris from Highway 101 through the area.
