Despite this week’s rain and snow, California is back to dry conditions again after a very wet 2017.  With about four weeks left in the normal wet season, the Sacramento Valley is at about 65% of average precipitation (less than 1/3 of last year’s precipitation).  The southern Central Valley has less than 50% of average precipitation and southern California is still drier.  Snowpack is much less, at 37% statewide.  Surface reservoirs, which almost all refilled and spilled in record-wet 2017, are now at 98% of average for this time of year, and will fall quickly as there is well-below-normal snowpack to melt.
