Overall, dry conditions have continued over New Mexico since mid-
January. Several weak weather systems moved through the region, but
most produced little or no significant precipitation over the
region. Two weather systems February 9-16 produced reasonably
widespread precipitation totals mainly west of the Central
Mountains. Although these systems provided some much needed
precipitation, overall deficits (especially in the Northern
Mountains) remain high enough to see the introduction of D3 or
Extreme Drought into portions of the Northern Mountains.

Over the last 30 days, most of the state has remained dry with
widespread precipitation totals of 25% or less. Some regions
(predominately the central Rio Grande Valley) are currently showing
30 day values of 100-300 percent of normal. This is due to the
weather system that moved through the state February 14-15  which
produced widespread rainfall totals of 0.40-0.60 with some reports
of over 1.00. This single precipitation event skews the percent of
normal calculations as the normal precipitation for the 30-day
period is approximately in the same range as the total precipitation
for the event.

Examining the 60 and 90 Day totals, a more cohesive pattern emerges
with most of the Land of Enchantment seeing precipitation departures
of less than 25% with many locations east of the Central Mountains
in the 10% or less range. As of February 14, some observing stations
in the Eastern Plains have not had measurable precipitation since

Corresponding to the low precipitation totals, current snowpack
values across the region are exceptionally low. As of February 17,
all basins within New Mexico are below 40% of average. The Rio Chama
basin is currently the highest with 38% of the average, with the
lowest values in the Mimbres Basin at 6% of normal. In Colorado, the
headwaters of the Rio Grande, Animas, and San Juan rivers are
doing better due to the recent systems with basin values of 47%, 49%,
and 50% of normal respectively.

The US Drought Monitor is a multi-agency, national analysis of
drought conditions that is produced weekly by the National Drought
Mitigation Center. The Drought Monitor is coordinated with over 400
local experts nationwide on local conditions to provide an accurate
analysis of conditions on a local and state level. The Drought
Monitor is released weekly on Thursday morning using data through
early Tuesday morning.

Looking at the Drought Monitor map for New Mexico as of Thursday,
February 15 2018, most of New Mexico is in D2, or Severe Drought.
D3, or Severe Drought, was introduced this week in portions of the
Tusas/San Juan and Sangre de Cristo Mountains due to the low snowpack
values. D3 also is present in a small portion of Catron County. D1,
or Moderate Drought, remains present over the southern tier of the
state. A very small area of D0 (Abnormally Dry) remains over southern
Otero County.

Currently, the primary impacts reported from the drought are in the
agricultural and winter recreation sectors. Reports from the USDA
National Agricultural Statistics Service (NASS) indicate that there
has been deterioration in the winter wheat conditions in the Eastern
Plains. Further data from the NASS indicate that supplemental feeding
 of livestock was increasing in some areas where natural feed was
becoming short.

Winter recreation is being severely impacted in New Mexico due to
the lack of snow. Recent snowfall totals have helped in some areas,
but as of February 16, at least two resorts are closed with one
reporting weekend openings only.

With respect to fire bans, four fire bans are known to be in effect
in New Mexico. The Villages of Angel Fire and Ruidoso along with
Mora and Colfax Counties have announced burn bans. Several New
Mexico State Parks have announced fire restrictions. At this time no
other restrictions are known. Please check with local, State, or
Federal agencies for current burn restrictions.

At this time, there are no known water restrictions due to the
recent dry conditions.


The current climate pattern is representative of La Nina, which is
present in the equatorial Pacific. Equatorial sea surface
temperatures (SSTs) are below normal with the most current Oceanic
Nino Index (ONI) value of -1.0C for November-January.

The ONI is a three month running average of the SST anomalies in the
Nino 3.4 region of the Pacific Ocean and is used to categorize if El
Nino or La Nina conditions exist. The NWS/Climate Prediction Center
uses an operational definition for El Nino or La Nina which looks at
the ONI along with consistent atmospheric conditions. Additionally,
these conditions must be expected to continue for at least the next
three consecutive months. Current models indicated that
conditions are likely to continue through the remainder of the
winter with SSTs returning to a neutral condition by Spring 2018.

The current seasonal temperature and precipitation outlooks were
issued by the NWS/Climate Prediction Center on February 15. The
March 2018 outlook for most of New Mexico indicates a trend to
normal to above normal temperatures with most of the southern two-
thirds of New Mexico expected to see normal to below normal
precipitation values. Conditions for March along the northern third
of the state are a bit more mixed with equal chances of above,
normal, or below normal temperatures and precipitation for most of
the region with the Four Corners likely to see normal to above
normal temperatures.

Looking out further for the March through May time period, the
outlook is reasonably similar with NM and the Southern Rockies
expecting normal to above normal temperatures with normal to below
normal precipitation.

Finally, the seasonal drought outlook for the same time period
indicates that drought is expected to persist over the remainder
of the region.


As of February 1, little change has occurred in reservoir storage
with many reservoirs in New Mexico at or above average storage
levels, especially on the Pecos and San Juan Rivers. Navajo Reservoir
on the San Juan River benefited from the above normal runoff in 2017.
The Pecos River reservoirs, which had a below normal 2017 runoff,
are seeing above average storage numbers due to the heavy rains late
in the monsoon season. Rio Grande reservoirs are showing below
average numbers* with upper basin reservoirs running at
approximately 75% of the 30-year average. Downstream, the Elephant
Butte Reservoir level is approximately 33% of average. Other
reservoirs through the state show varying trends with Conchas Lake
slightly above average while Eagle Nest is about 80% of the longer
term average.

28-Day average streamflow values show patterns consistent with the
2017 runoff and monsoon but are continuing to deteriorate due to the
ongoing above normal temperatures and below normal precipitation. In
general, most natural flowing basins east of the Central Mountain
Chain are showing above normal streamflow for the period as late
monsoon season rainfall helped to recharge soil moisture. The
prolonged dry period with above normal temperatures has continued to
deplete the moisture from the upper levels of the soil column, which
is still evident in some natural flowing basins in the far Eastern
Plains (such as Revuelto Creek). West of the Central Mountain Chain,
streamflow values for natural basins are representative as well of
the 2017 runoff and monsoon season with many locations reporting 28-
day streamflow values of less than 5% of normal.

Due to the low snow totals throughout Southern Rockies and New
Mexico, current runoff outlooks for the 2018 runoff season are
remaining low. Below is a table of selected locations and the
current most probable (50th percentile) runoff forecast:

River                                     Percent   Period
Rio Grande River at Otowi Bridge            21%     Mar-Jul 2018
Pecos River at Santa Rosa Lake (Inflow)     11%     Mar-Jul 2018
Canadian River/Conchas Reservoir Inflow     11%     Mar-Jun 2018
San Juan River at Farmington                42%     Apr-Jul 2018
Gila River near Gila                        26%     Feb-May 2018
San Francisco River near Glenwood           32%     Feb-May 2018

*  Long term averages for reservoirs use data from the 1981-2010
period. During this time, reservoirs along the Rio Grande had
higher storage values due to a wetter period that impacted the
first half of the 30 year period. Therefore, the 30-year average
is statistically skewed to a higher value and may not be reflective
of reservoir storage trends for the previous 15 years.
