San Francisco is not alone in its rain-free streak. Oakland and Sacramento have yet to have any measurable rainfall in 2015. These are the extremes, but almost all of northern California will finish the month well below the average precipitation for the normally wet month of January.
As most of California grapples with extreme drought conditions, forecasters had anticipated a wetter-than-average month in January. December was especially wet with 11.7 inches of rain. Then January swept through and essentially erased all the progress made late last year.
