...Extreme Drought spreads across Southeastern Colorado...

SYNOPSIS...Updated

Spring weather systems through out the month of May have produced
beneficial precipitation across the State of Colorado. However, the
bulk of the precipitation has been focused across northern portions of
the state, with the precipitation received across Southern Colorado
more spotty, and not enough to overcome the extremely warm and dry
weather that was experienced over the Fall and Winter of 2017-2018.

With that said, the latest US Drought Monitor, issued Thursday May
24th, 2018 has expanded Extreme Drought (D3) conditions across most
of eastern Pueblo County into Crowley County and southwestern Kiowa
County.

The current Drought Monitor continues to indicate Exceptional Drought
(D4) conditions across the Sangre de Cristo Mountains of Southern
Colorado, which includes portions of Costilla, Las Animas, Huerfano,
Alamosa, Custer and Saguache Counties.

Extreme Drought (D3) conditions continue to be depicted across most of
Southern Colorado including Mineral, Rio Grande and Conejos Counties,
southern portions of Saguache County, the rest of Alamosa and Costilla
Counties, southern portions of Custer County, southwestern through
northeastern Pueblo County, most of Crowley County, southwestern Kiowa
County, Otero and Bent Counties, most of Prowers County, Baca County
and the rest of Huerfano and Las Animas Counties.

Severe Drought (D2) conditions are depicted across southwestern portions
of Chaffee County, the rest of Saguache and Custer Counties, southern
portions of Fremont County, the rest of Pueblo County, southwestern
through northwestern portions of El Paso County, as well as northern
portions of Crowley and Prowers Counties and the rest of Kiowa County.

Moderate Drought (D1) conditions remain indicated across southwestern
Lake County, the rest of Chaffee and Fremont Counties, as well as Teller
County and the rest of El Paso County. Abnormally dry (D0) conditions
continue to be indicated across eastern Lake County.

DROUGHT IMPACTS...

FIRE DANGER...

Warm and dry conditions across the region over the past several
months, combined with abundant cured fuels, has allowed for moderate
to high fire danger to develop and persist across much of South
Central and Southeast Colorado. The recent precipitation and warm
weather has prompted some sporadic green up and tempered fire danger
some across portions of the Southeast Plains, however, many land
management agencies continue to enforce fire bans and restrictions.

The latest information on fire bans and restrictions can be found at:

www.coemergency.com/p/fire-bans-danger.html

AGRICULTURAL...

The very warm and dry late Fall and Winter has helped to dry out soil
moisture across south central and southeast Colorado, with the greatest
deficits being realized across the Southeast Colorado Plains.

Those relying on agricultural water from snow melt, streamflow
forecasts for the Spring and Summer continue to be below average
statewide. Near to below average flows are projected across
northern portions of the state, with below to well below average
flows expected across the southern portions of the state.

HYDROLOGIC...

The May 1st statewide snowpack came in at 57 percent of median and is
only 59 percent of the snowpack available at this same time last
year. The statewide snowpack continues to indicate the best conditions
across northern portions of the state, with rapidly diminishing conditions
across southern portions of the state.

In the Arkansas Basin, May 1st snowpack came in at 52 percent of
median, and is only 42 percent of the available snowpack at this same
time last year. As with the state as a whole, there remains a big
difference in the distribution of said snowpack, with the northern
portions of the Arkansas Basin coming in at 73 percent of median,
while the southern portions of the basin were running at or below 5
percent of median.

In the Rio Grande Basin, May 1st snowpack came in at only 12 percent
of median, which is only 12 percent of last years snowpack at this
same time.

Water storage across the state at the end of April was around 111
percent of average overall, as compared to 113 percent of average
storage available at this same time last year.

In the Arkansas Basin, end of April storage was at 129 percent of
average overall, as compared to 106 percent of average storage
available at this same time last year. Reservoir storage in the
Arkansas Basin at the end of April was the highest in the state.

In the Rio Grande Basin, end of April storage was at 115 percent of
average overall, as compared to 99 percent of average storage available
at this same time last year.

With below to well below median snowpack, which may have already
melted out across portions of Southern Colorado, streamflow forecasts
for the Spring and Summer continue to be below average statewide.

In the Arkansas Basin, current streamflow forecasts range from 64
percent of average at the Arkansas River at Salida, to only 8 percent
of average for Grape Creek near Westcliffe.

In the Rio Grande Basin, current streamflow forecasts range from 36
percent of average for the inflow at Platoro Reservoir, to only 3
percent of average for the San Antonio River at Ortiz.
