...DROUGHT INCREASES OVER EASTERN UTAH AND WESTERN COLORADO...

SYNOPSIS...
Drought categories have increased over eastern Utah and
western Colorado with extreme drought pushing northward and eastward.

Fall precipitation and winter snow accumulation so far are much
below normal for the season for both eastern Utah and western
Colorado. The dry conditions have continued for the past four to
five months. Precipitation in the southern valleys for February has
been below normal. The mountains of southwestern Colorado received
more precipitation than the valleys and actually near to slightly
above normal for the month of February although long term
precipitation remains well below normal.

SUMMARY OF IMPACTS...
Areas in D3...Extreme Drought...include all of
Montezuma county and portions of La Plata, Dolores, San Miguel,
Ouray, Montrose, Delta and Mesa counties of western Colorado. In
eastern Utah portions of Grand and San Juan counties. The increase
in drought severity is due to low soil moisture, lack of snow pack,
low stream flows, wildland fire impacts, and agricultural impacts to
both winter crops and grazing land.

Areas in D2...Severe Drought...include all or portions of San Juan,
Grand, and Uintah Counties in Utah. In Colorado the counties include
all or portions of La Plata, Dolores, San Miguel, San Juan, Ouray,
Hinsdale, Montrose, Delta, Mesa, Garfield, Rio Blanco, Eagle,
Pitkin, Gunnison and Archuleta.

CLIMATE SUMMARY...
Winter season snow pack is much below normal for the higher
elevations so far. Many SNOTEL sites are in the lowest 5 years for
the period of record. February did bring moisture to the area but
not enough to change drought impacts. Western Colorado combined
basins snow water equivalent increased from 52 percent to 69 percent
of normal this past month. Southeastern Utah snow water equivalent
increased from 34 percent to 51 percent of normal. Valley
precipitation has also been much below normal since the end of
summer. So far for January, valley precipitation in Utah has been
well below normal with Colorado locations slightly below to near
normal for the water year.

PRECIPITATION/TEMPERATURE OUTLOOK...

Into the month of March, there is a better than average chance of
above normal temperatures and better chances of either of below
normal precipitation for the next six weeks across eastern Utah and
western Colorado.

Current observations show that the ENSO cycle is and will continue
in a La Nina phase. There is a likely transition to neutral
condition mid to late spring.

HYDROLOGIC SUMMARY AND OUTLOOK...
Average seven day and 28 day stream flow has been well below to
just below normal for southeastern Utah and southwestern Colorado
The Animas and San Juan River Basins are much below normal and the
Gunnison River has been normal mainly due to reservoir releases.

NEXT ISSUANCE DATE...
This product will be updated if necessary in response to
significant changes in conditions.
