April showers may be more scarce than normal north of Point Conception in California, according to an outlook produced by the National Oceanic and Atmospheric Administration.

This area where the probability of precipitation is below normal includes virtually all of Northern California and the crucial northern Sierra Nevada, where the state’s largest reservoirs are located.

While snow cover has increased thanks to a series of March storms, the Northern Sierra 8-Station Index stands at 56% of normal for the season. As of March 24, another 29.25 inches would be needed to reach the season normal of 54.52 inches.
