You are now in California and the U.S. category.

On Tuesday, state water officials trudged into the Sierra Nevada for the first snowpack survey of 2017. Snowpack levels are crucial indicators of whether California will have enough water after the winter, as the melting snow flows into the state’s reservoirs. The reading at Phillips Station, near Lake Tahoe, however, is a largely ceremonial exercise, attracting attention in part for its visual interest. (See photos below.) After dipping poles into the snow, surveyors said the snowpack there was at roughly half the historical average.

The multi-day siege of flooding rain and Sierra snow has begun in California, which may eventually prove to be too much of a good thing for residents still thirsting for relief from a five-year drought. Several landslides were reported in parts of northern California Tuesday night and early Wednesday, particularly in Santa Cruz County. Up to 2 feet of water was reported near downtown Yountville, and two right lanes of the 101 freeway in downtown San Francisco were flooded by a couple feet of water.

Yosemite National Park expects so much rain, snow and possible flooding over the next several days and into the weekend park officials say they may close the whole park. Citing visitor and employee safety amid predictions for significant rainfall in Yosemite Valley that put the Merced river well above flood stage, park officials say that people planning trips to the park, beginning tomorrow, Thursday January 5, 2017, should make alternate plans as the park may close. A Yosemite area forecast is in our weather section here.

Droughts are already getting longer and more severe because of human-caused climate change in the American Southwest and around the world. But the drought-climate connection goes both ways: California’s prolonged dry spell has also made climate change a little bit worse.

The several feet of snow expected in the Sierra this week is expected to considerably change the look of California’s drought map. At this time last year, 45 percent of the state was in an exceptional drought, which is the worst possible rating. Officials said only 18 percent of California currently remains dry.
