Not only does the dwindling snowpack put California's water supply at risk, it also portends more floods, wildfires, and mudslides over the coming year. This is precisely what makes climate change so dangerous. Even small changes in weather can have cascading effects, multiplying the risk of ... drought
Melting ice in the Arctic might seem a world away from California's farms and aquifers. But droughts in the state could get worse as the Arctic melts. Summers in the Arctic Ocean are expected to be ice-free within a few decades. When that happens, the precipitation California receives could decrease ...

The latest national weekly drought reading, compiled by U.S. government agencies, shows 41 per cent of California in drought, an improvement from 48 per cent two weeks earlier. A storm forecast for the end of the week is expected to be a warm one, adding little more to the state's snowpack, officials said.
About 40 percent of California was still under some type of drought status despite recent rain; the majority of San Diego County was under a "moderate drought" designation with a small portion of the county's desert area under a "severe drought" designation.

With the region experiencing drought conditions since 2000, even California, which has senior rights, came to the negotiating table. State officials said they were willing to voluntarily reduce Colorado River allocations to keep water levels in Lake Mead – the reservoir that holds water behind Hoover Dam for ... California

An early March storm helped slow California's descent back into its dry spell, but similarly, the most recent, much-hyped intermittent downpour in Los Angeles, Ventura and Santa Barbara counties will probably yield little snowpack, at least relative to what is needed to pull the state out of its drought. California
How much are Californians willing to pay and sacrifice for a more sustainable state? It takes a lot of commitment and persistence – and that's something of a question mark with the latest developments on water conservation and recycling. Local water districts are rebelling against permanent statewide rules ... California
The research revealed two nine-year droughts in California history: one starting in 1452 and another beginning in 1775. The most recent drought was relatively compact, lasting just five years, but appears to have set records for dryness, said Dave Meko, an Arizona professor who led the tree-ring analysis. California
Despite the recent storm that pummeled the Sierra with snow and scattered rain in the valleys and along the coast, California remains unseasonably dry with 47 percent of the state experiencing at least "moderate drought" conditions, according to the federal government's Drought Monitor. The storm hailed ... California
So why isn't there more panic about a potential drought? The state's reservoir levels and drinking water supply are in good shape, largely because last year was exceptionally wet, said Dave Rizzardo, of the California Department of Water Resources. Last week's storm nearly doubled the snowpack — and ... California

Department of ... This year's conditions are a reminder of the state's cycle of drought and recovery. California
With water resources so heavily managed, California is able to weather droughts reasonably well. Severe meteorological dryness can impact landscape and rangeland conditions while water supply conditions may be much better off. This makes it difficult to assess drought impacts. While some reservoirs ... California
Grapevines are drought resistant enough that California's wineries may be able to dial back the irrigation and keep their plants alive, new research says. That's good news as the state heads into what looks to be another dry year. There is a catch, however: while the study suggests vines might survive a ... California
California earthquakes are a geologic inevitability. The state straddles the North American and Pacific tectonic plates and is crisscrossed by the San Andreas and other active fault systems. The magnitude 7.9 earthquake that struck off Alaska's Kodiak Island on Jan. 23, 2018 was just the latest reminder of ... California
The 2017-18 wet season in California has been dry. As a result, Sierra snowpack is low for the time of year, rivaling 2014 and 2015.
