Northern California rain and snow levels have soared with record wet weather in May, leaving the Sierra with higher-than-normal snowpack levels and pushing several reservoirs toward full capacity. Downtown Sacramento already has broken record rainfall numbers in May, with more than 3.42 inches of rain this month, according to National Weather Service forecaster Karl Swanberg. The previous record of 3.25 inches was set in 1889. Current statewide snowpack levels are being recorded at 20 inches of “snow water equivalent,” the depth of water that would result if the snowpack melted at once, a figure that is 167 percent above average for this time of year, according to the California Department of Water Resources.
