What drought has meant in New Mexico

The National Drought Mitigation Center's examples of impacts observed in New Mexico at each level of drought, starting with this week's worst here.

D2 Severe drought This week

  • Abundance and magnitude of wildfires may increase; fuel mitigation practices are in effect
  • Dust storms occur
  • Irrigated crops are stunted; dryland crops are brown
  • Pasture yield is limited; producers sell livestock
  • Well water decreases
  • Wildlife feeding patterns change

D0 Abnormally dry

  • Fire danger increases
  • Soil moisture is low

D1 Moderate drought

  • Burn bans and firework restrictions begin
  • Livestock need supplemental feed and water

D3 Extreme drought

  • Fire danger is extreme
  • Irrigation allotments decrease
  • Livestock are suffering; producers are selling herds; feed costs are high; emergency CRP grazing is authorized; crop yields are low
  • Vegetation and native trees are dying

D4 Exceptional drought

  • Bears encroach on developed areas; migratory birds change patterns
  • Federal lands begin to close for fire precautions; burn bans increase
  • No surface water is left for agriculture, farmers use private wells
  • Rio Grande and other large rivers are dry

Drawn from the Drought Impact Reporter and local observers.

Burn bans and water restrictions

The Drought Monitor does not issue burn bans or water restrictions. San Juan County's officials, the state forestry or fire agency, and local water utilities set them, often once drought reaches D2 or dry fuels raise the fire danger. Check the county's emergency management office or fire marshal for a ban in force, and the alerts page for red flag warnings and fire weather watches.

This week in the West

The Drought Monitor authors' narrative for the map of Sep 29, 2026, released Oct 1, 2026.

Outside of Arizona, New Mexico, and Colorado, which experienced deep and substantial drought-busting rainfall this past week, the western states generally had unchanging drought conditions. The Pacific Northwestern states of Washington and Oregon began experiencing the first of its fall rainy systems, helping to ease drought pressure across western Oregon, where drought was downgraded in a couple spots. Drought and dryness also improved in southwest Montana and northwest Wyoming this past week.

Looking ahead

Ongoing substantial rain was falling Tuesday morning at the onset of the new U.S. Drought Monitor week, from Arizona and New Mexico into the Central and High Plains. This excessive rainy system connected to Hurricane Polo is projected to continue eastward this week into the High Plains, Midwest, and South regions. The Weather Prediction Center has moderate threats for excessive rainfall from the Southwest into Texas, Oklahoma, northward into Nebraska and Iowa. Drought-busting rains may be possible across the South as this weather system evolves this week. Looking into the next week, the Climate Prediction Center’s 6–10-day outlook indicates that well-above average temperatures will shift into the western states, along with below normal precipitation chances. Meanwhile, above average precipitation chances are projected from southern Texas into the southeastern states, including Florida. Above average precipitation chances are also projected for southeastern Alaska, with near neutral rainfall forecasts for Hawaii.

What this means

The five categories the Drought Monitor draws, and how the map is made.

D0 Abnormally dry
Going into or coming out of drought.
D1 Moderate drought
Some damage to crops and pastures; water shortages developing.
D2 Severe drought
Crop or pasture losses likely; water restrictions imposed.
D3 Extreme drought
Major crop and pasture losses; widespread water shortages.
D4 Exceptional drought
Exceptional and widespread losses; water emergencies.

The US Drought Monitor is drawn every week by authors at the National Drought Mitigation Center, USDA and NOAA, who weigh rainfall, soil moisture, streamflow, groundwater, vegetation health and reports from local observers. Each map shows conditions through Tuesday morning and is released on Thursday. It shows where drought is and how bad it is; it does not forecast it. CPC's outlooks do that.
