Residents in Southern California are bracing for the third and final expected winter storm as Friday's system brought heavy rain and high winds that toppled trees, downed power lines and flooded and closed streets.
A more powerful system is expected to hit the area on Sunday.
Friday's storm was expected to be the coldest but not the wettest of the three.

Mud flowed from a Duarte hillside into a residential neighborhood, forcing its way around and through K-rails into the front yards of several homes.
