Nawaf al-Akhras describes the daily round trip to a water filling station as a torment for his family, stating, 'My entire day with my son is spent waiting in line to fill water, with people coming from very far distances.'

The Trump Administration's sweeping changes to the Forest Service, which operates under the Department of Agriculture, represent a gutting of an agency that has been a stable fact of life for over a century.

The storm will begin warm and wind-affected on Friday, with snow levels starting around 7,000 to 8,000 feet, leading to wet conditions at lower elevations initially.

The Colorado River is an interconnected system, sustained by Rocky Mountain snowpack, rainfall and groundwater. It is fragile, and under increasing stress. Two and a half decades into this century, the river that built the modern West has 20% less water flowing through it than it did on average in the last century. As heat and drought intensify, so do the stakes: Failure to recognize the severity of changing conditions, managing the river in parts without considering needs of the whole and inadequate planning for long-term shortages put the future of all the basin at risk.

SWE is the most important metric for all of our water resources. It's the metric that we deal with the most and the one that the entirety of the snow research and operations community is working to get right. So, seeing an increase in SWE like that, even if it's from mid-winter rain, is a great thing because that means we have more water stored in the snowpack moving forward.

Western water law is based on the prior appropriation doctrine, which gives the first entity to make "beneficial use" of water the right to keep on using that amount, even if that means that upstream "junior" users' spigots will get shut off. By the early 1900s, a rapidly growing California was enthusiastically diverting the Colorado River, with huge irrigation districts gobbling up the senior water rights.

To get back to average snowpack, we essentially need to have the most snow that we've ever had for the last 30 years between now and mid-April. It would be extremely difficult for Colorado to get back to a normal/average snowpack. As an example, when looking at the Independence Pass SNOTEL site in central Colorado outside of Aspen, we typically have 13 inches of snow-water-equivalent at the end of February. This year, we only have 6.7 inches of SWE.

"A dry January, which is historically the wettest month of the year in California, has now eroded the gains made at the start of the year and forecasts currently show no major precipitation in the next two weeks," California Department of Weather Resources spokesperson Jason Ince wrote in a Jan. 30 news release. The first month of the year certainly left the area warmer and drier than usual, weather officials confirmed.
