Drought Information Statement
National Weather Service Denver/Boulder CO
126 PM MDT Thu Mar 16 2017

...Drought intensifies along the Front Range Urban Corridor...

Drier and warmer than normal conditions occurred in the Colorado
River headwaters and continued across eastern Colorado with gusty
winds common. The warm...dry and windy conditions produced much
above normal evaporative demand in eastern Colorado as noted on the
Colorado NIDIS Weekly Drought Summary. There have been grass and
brush fires from the lower Front Range Foothills eastward.
Vegetative conditions have continued to deteriorate in recent weeks.
Winter wheat is not coming up in some areas...including Lincoln
County. Most of Lincoln County on the east central plains remained
in a Severe Drought /D2/...with reports of blowing dust producing
low visibilities.

Local Areas Affected...
Severe Drought /D2/ was expanded to include both the Denver Metro
area and the northern I-25 Urban Corridor from Wellington south to
Berthoud. Moderate Drought /D1/ continued elsewhere except for
Abnormally Dry /D0/ conditions in the high country immediately east
of the Continental Divide and on the far north central plains. There
were no drought designations west of the divide on the March 14th
U.S. Drought Monitor.

Hydrologic Summary...
There was less snowfall from February through mid-March compared
with the previous two months. On February 1st the mountain snowpack
was around 155 percent of normal. By March 16th snowpack ranged from
116 percent of normal in the South Platte Basin to 128 percent of
normal in the upper Colorado River Basin. The mountain snowpack
typically does not peak until April. However...basin snowpack is
already between 90 to 115 percent of the normal peak snowpack.

March 1st basin reservoir storage was 107 percent of average. This
is similar to the storage last year. The majority of U.S. Geological
Survey gages continued to record near normal streamflow. Below
normal to moderate hydrologic drought continued along the Arikaree
and South Fork Republican Rivers as well as Frenchman and Spring
Creeks on the far east and northeast plains on the USGS Colorado

Climate Summary...
It has been drier and warmer than normal since February 1st.
