Drought Information Statement
National Weather Service Denver/Boulder CO
653 PM MST Thu Feb 16 2017

..Drought conditions continue east of the Continental Divide...

Synopsis...
Moderate Drought /D1/ was added to northern Washington and southwest
Logan Counties on the February 14th U.S. Drought Monitor. This area
has received well below normal precipitation for the water year to
date and recent weather has been hot and windy.

Local Areas Affected...
Widespread Moderate Drought /D1/ or Abnormally Dry Conditions /D2/
continued to be observed east of the Continental Divide. There were
no drought designations west of the divide on the February 14th U.S.
Drought Monitor. A very small area of Severe Drought /D2/ lingers in
northwest Lincoln County on the east central plains.

Hydrologic Summary...
The Colorado River basin snowpack on February 16th was 144 percent
of normal and nearly reaching the peak normal snowpack (99 percent
of the peak). In a typical year the snowpack is only 69 percent of
the peak snowpack at this time with April 10th being the normal peak
date as reported by the Natural Resources Conservation Service.

The mountain snowpack in the South Platte River basin was 138
percent of normal and 85 percent of the normal peak snowpack. In a
typical year the mid-February snowpack is only 61 percent of the
peak snowpack with the normal peak date being April 27th.
Therefore...there is still plenty of time remaining for the snowpack
to rise above the normal peak.

Liquid water in the mountain snowpack generally ranged form 8 to 40
inches. Basin reservoir storage continued to hold fairly steady at
105 percent of average and 73 percent of capacity at the end of
January. 85 percent of the U.S. Geological Survey stream gages had
normal to above normal flows in mid-February.

Climate Summary... The mountain snowfall has been well above normal,
but numerous locations from the lower foothills eastward have had
well below normal snowfall. Water year precipitation generally
ranged from 105 to 155 percent of normal in the mountains above 8000
feet. However...numerous locations below 8000 feet have received 75
percent or less of their normal precipitation. Unofficial NWS
Cooperative Observer precipitation totals for the water year so far
beginning October 1st 2016 are listed below:
