Current Conditions in the Intermountain West DEWS

Sample of US Drought Monitor for Upper Colorado River Basin
Drought severity levels in the West.
Sample of Monthly Palmer Modified Drought Index
The PDSI represents drought severity, framed from the perspective of soil moisture or dryness. The Palmer metrics are computed based upon a location’s recent precipitation, recent atmospheric evaporative demands, and its soil characteristics.
Sample of 5-day QPF forecast
Total accumulated precipitation forecast maps for the Intermountain West, inclusive of county borders, to identify expected precipitation and potential drought. Updated twice daily.
Sample of One-month SPEI
The Standardized Precipitation-Evapotranspiration Index (SPEI) indicates how unusual a combination of precipitation and evapotranspiration (the atmospheric demand for water) is, compared to the historical record over a given time scale.
Sample of One-Month Standardized Precipitation Index
The Standardized Precipitation Index (SPI) indicates how unusual the amount of accumulated precipitation is, compared to the historical record over a given time scale.
