First…. back on January 1st, Northwestern snowpack was running anywhere from 25 to 75 percent of average. But following a month of heavy precipitation from the Cascades to the northern Rockies, just about every northwestern basin has now at least average, if not above average snowpack. Yet USDA meteorologist Brad Rippy says for California, and much of the southwest, the beginning of January, the Sierra Nevada key watershed areas were looking pretty good with a snowpack that was near to slightly above average. But during the month of January, we saw less than half of the normal precipitation falling across that region, and that resulted by the end of January, snowpacks that have now dropped to about 70 percent of average.
He adds the storm track will continue through the Pacific Northwest and northern Rockies the next two weeks, while drier conditions persist in California and the Southwest.
