New Mexico Drought Monitor

The New Mexico Drought monitor is a subset of the United States Monitor, issued every Thursday morning, based on drought conditions the previous Tuesday. The map below shows the current drought level around the state, and the percent of New Mexico land area in each drought level compared to the previous week.

Read an explanation of the drought intensities and what they mean.

Hydrologic Outlook
National Weather Service Albuquerque NM

...APRIL 2017 NORTHERN NEW MEXICO WATER SUPPLY OUTLOOK...

...EXISTING CONDITIONS...

As of April 14, 2017 the USGS measured 14 day streamflow for
most of the region remains near normal for this time of year. 
Lower than normal streamflows can be found at some locations, 
either due to regulation changes or longer term deficits in 
precipitation and soil moisture.

Recent soil moisture data from the NASA SPoRT LIS model continues
to show soil moisture deficits over most of eastern New Mexico 
and along the Rio Grande Valley from Albuquerque south. Some of 
these deficits are primarily in the top soil as a result of 
drought conditions that developed in March while other deficits 
(mainly in the mid to lower levels of the soil column) are long 
term deficits.

...PRECIPITATION...

March 2017 was an exceedingly dry month for New Mexico as high 
pressure dominated the area for the first three weeks of the month.
The storm track kept precipitation out of most of the state 
except for some areas along the Northern Mountains. A pattern 
change during the last few days of the month allowed for some 
widespread rainfall over much of the state, however many areas 
still saw less than 10% of their normal monthly rainfall totals 
with some stations reporting zero precipitation for the month.

For the 2016-2017 Water Year, most of the state is running near to 
above normal precipitation through April 13th with the highest 
totals being west of the Central Mountain Chain. A "boom-bust" 
pattern over New Mexico has led to 30-45 day dry periods being 
followed by 14-21 day periods of a more active weather pattern. 
The eastern third of the state (mainly east-central and southeast 
NM) continues to show precipitation values below normal for the 
water year.

...SNOWPACK...

As of April 1st, snowpack data from the USDA/National Resource 
Conservation Service (NRCS) indicate that the snowpack 
(specifically snow water equivalent, or SWE) values for the 
northern basins of New Mexico are generally at or above normal 
with exceptions of the Pecos, Cimarron, and Jemez River basins. 
The above normal temperatures during most of March started 
snowmelt on the Jemez Basin while melting some of the snow out of 
the already below normal Pecos and Cimarron Basins. Basins in the 
southern half of New Mexico are considered melted out as of April 
1.

...STREAMFLOW FORECASTS...

NWS River Forecast Centers, in conjunction with our partners in the
NRCS, USACE, and the USBR, produce seasonal streamflow forecasts
for selected river locations and basins in New Mexico. These
forecasts are based on hydrologic conditions as of the 1st of the
month and may not reflect current trends and forecasts.

As of April 1, most basins impacting New Mexico are expected to
have near or normal runoff volumes through the forecast period due
to the large snowpacks available for runoff. The Pecos and San
Francisco River are expected to have near to below normal
runoff volumes.

...DROUGHT...

Widespread abnormally dry conditions exist over most of New Mexico 
as a result of the abnormally dry and warm conditions during most
of March. This combination resulted in a flash drought which 
rapidly dried the topsoil in many areas. Precipitation the last 
week of March helped to ease these conditions over much of the 
impacted areas. Drought status for NM is re- evaluated weekly and 
can be found at the National Drought Mitigation Center website at 
http://droughtmonitor.unl.edu.

...OUTLOOKS...

SHORT-TERM OUTLOOK
The 8-14 day temperature and precipitation outlooks issued by the 
NWS/Climate Prediction Center continue an increased probability 
of normal to above normal temperatures with normal to slightly 
wetter for most of New Mexico. Please refer to the latest 
forecasts for more current weather information.

LONG-TERM OUTLOOK
The NWS/Climate Prediction Center has ended the La Nina Advisory 
and ENSO neutral conditions exist over the Pacific Ocean. Models 
guidance is expecting the neutral ENSO conditions to continue for 
the spring and into Summer 2017. The current CPC forecast for 
April through June 2017 continues the increased likelihood of 
warmer temperatures New Mexico. Climate signals that help to 
forecast precipitation over the Spring months during an ENSO 
Neutral pattern are weak, so equal chances of above, below, and 
normal precipitation is expected. These outlooks are issued 
monthly with the next outlook to be issued on March 16th. Outlooks
can be found at the NWS/CPC website at 
http://www.cpc.ncep.noaa.gov

SPRING FLOOD OUTLOOK
At this time, the risk of spring flooding remains average for basins
with near to above normal snowpack values and below normal for basins
with below normal values. The only basins of note are the San 
Juan and Animas River Basins. Both of these basins have well above
normal snowpack values. While normally flooding does not occur 
solely due to spring runoff, minor flooding could be possible if 
there is a heavy rainfall event that coincides with peak runoff 
flow. 

Many factors impact the likelihood of spring flooding, including snow 
pack and hydro- meteorological conditions at the time of runoff. 
While spring snowmelt related flooding is not usually expected on 
most mainstem rivers in New Mexico due to regulation, conditions 
will have to be monitored as the season progresses for the 
potential of higher than normal peak flows on unregulated rivers.

The NWS Albuquerque Hydrologic Service Area (HSA) is serviced three
river forecast centers: West Gulf RFC (Ft Worth, TX), Arkansas-
Red Basin RFC (Tulsa, OK), and the Colorado River Basin RFC (Salt
Lake City, UT). These RFC`s issue a variety of hydrologic forecast
products during the year. Further products and current
information can be found at the following locations:
