"Snowpack Near Record Lows Spells Trouble for Western Water Supplies"

"Scientists say snow seasons like the U.S. West is experiencing now will become more common as global temperatures rise, and economic costs will go up, as well."

"Months of exceptionally warm weather and an early winter snow drought across big swaths of the West have left the snowpack at record-low levels in parts of the Central and Southern Rockies, raising concerns about water shortages and economic damage.

Drought spread across large parts of the Western United States this month, and storms that moved across the region in early January made up only a small part of the deficit. Runoff from melting snow is now projected to be less than 50 percent of average in key river basins in the central and southern Rockies.

Most of the region's annual water cycle starts as thick layers of mountain snow that accumulate during winter and melt slowly in spring. If the snows don't come, there's no water to fill the reservoirs."
