Across the West, the winter is off to a dry start. Wide swaths of the Rocky Mountains have lower-than-average snow totals for this time of year, but scientists say there鈥檚 still plenty of time to end the 鈥渟now drought鈥� and close the gap.
High-altitude snowpack has big implications for the region鈥檚 water supply. Two-thirds of the Colorado River鈥檚 water starts as snow in Colorado鈥檚 mountains before melting and flowing to about 40 million people across seven states.
Nearly every part of Colorado, Utah and Wyoming has significantly less snow than usual for late December. The from a region-wide network of snow sensors shows snow in many areas with snow totals around 60 or 70% of normal.
鈥淚t鈥檚 really going to be dependent on what we see in January and February,鈥� said Becky Bolinger, Colorado鈥檚 assistant state climatologist. 鈥淲e鈥檙e really going to need an active January and February to make up these deficits and be okay.鈥�
Last year, big snows in the Rockies helped boost the Colorado River鈥檚 major reservoirs. Policymakers said the snowy winter lifted some pressure off of tense negotiations about sharing the river鈥檚 water in the future.
Even a few consecutive wet winters aren鈥檛 enough to seriously fix the supply-demand imbalance that fuels the West鈥檚 water crisis. More than 20 years of dry conditions, fueled by climate change, have shrunk the Colorado River鈥檚 water supply, and policymakers have been unable to agree on significant, long-term cutbacks to water use.
Experts say it would take five or six consecutive above-average winters to close that supply-demand gap, which is unlikely to happen as climate change makes the region warmer and drier.
Dan McEvoy, regional climatologist at the Western Regional Climate Center and Desert Research Institute, said last year鈥檚 wet winter was an 鈥渁nomaly.鈥�
鈥淟ots of data, lots of research, projections, modeling, all point to this continuing trend of warmer winters, less snow and in some cases, less precipitation,鈥� he said.
Last year鈥檚 snowy conditions did deliver one major positive for the Colorado River 鈥� soaking the soil and helping this year鈥檚 snow reach the streams, rivers and reservoirs where people collect water. Dry soil acts like a sponge and soaks up runoff. After a high-snow winter, the soggy soil will help make sure a higher percentage of the next year鈥檚 snowfall reaches waterways.
Despite the low snow, ski resorts may not be feeling much financial pain. Chad Dyer, managing director of ski website OnTheSnow, said a lot of ski traffic around the holidays is coming from tourists who cemented their plans in advance.

鈥淭heir flights are booked, their lodging is booked. As long as the ski resort is open and has got a product, by and large, they're going to visit,鈥� Dyer said.
Dyer also pointed to statistics from a recent Vail Resorts . The mountain ownership company said it expects 73% of its worldwide skier visits come from season passholders. That high volume of pre-purchased lift tickets allows ski resorts to depend less on ticket sales that may ebb and flow with the quality of ski conditions.
The next few weeks are unlikely to bring much immediate relief for Western mountains.
鈥淭he medium鈥� to long鈥搑ange forecasts that go out about two weeks are not super promising,鈥� McEvoy said. 鈥淭here are some signs of some smaller storms that can impact parts of the West. But overall, it's a pretty dry forecast.鈥�
