Rainstorms in California

California is having a rough couple of weeks.  Over the weekend a huge rainstorm hit Southern California.  They received between 2-6 inches of rain, with almost 10 inches of rain in some areas.  Because the ground was already oversaturated from what has been a very wet winter, there were major flash floods and a few sinkholes.  There is also a higher probability for mudslides after all of the rain, which could cause more damage.  Southern California has received 400% more than the average rainfall this winter.  And the rain is continuing over Northern California where the Oroville Dam is located.  The spillway is still eroding, but the dam has not broken yet.  All of this rain is causing damaging amounts of erosion.
