Entire state blanketed with snow in early Feburary
A pair of storms that bookended January helped raise the statewide snowpack level to 111 percent of average as of Feb. 1, according to the Natural Resources Conservation Survey.
Satellite images and other remote sensors operation by NOAA’s National Operational Hydrologic Remote Sensing Center storms left nearly the entire state blanketed in snow. Without those two storms, January snowfall would only have been about 70 percent of average for the month, said Brian Domonkos, Colorado Snow Survey supervisor with the NRCS.
Snowfall continued through February 3, which increased snowpack totals to as high as 117 percent of normal as of Feb 4. The mountains of Southern Colorado saw the greatest increase in snow-water equivalent. From January 28 to February 3. total snowpack depth increased as much as 30 inches at the Cumbres Trestle SNOTEL in the San Juan Mountain range.
As of February 1, the snowpack was below average in only a handful of minor watersheds. All other drainages were above to well above normal. While the late January storms benefitted the entire state, January precipitation as a whole was particularly slim in the Arkansas and Upper Rio Grande basins and storms only amounted to about 75 percent of normal monthly snowpack accumulation.
