Late snow is the best snow for snow pack and water into the spring and early summer.
Sierras gonna get another blast.
Snow is snow. The formal water-planning snow pack water-equivalent measurements occur on April 1. Snowfall later than that is a treasure for skiers, but doesn't add much to the water supply - unless it is at the end of a dry winter. This year is unusual because while there has not been much snow, there has been a lot of rainfall in conditions too warm to come down as snow. All the water project reservoirs are near or above historic averages for this date (except Oroville, which has been kept low while repairs to the spillway are completed).
