Short-Term Drought Indicator Blend
EXPERIMENTAL

These experimental drought blends integrate several key drought monitoring products and indices into a single short-term or long-term product, based on the methodology developed at the NOAA Climate Prediction Center. The blends are created using the Climate Engine tool, and apply the CPC weighting ratios to the high-resolution gridMET gridded research dataset. The data is updated daily, with a delay of 2 to 3 days to allow for data collection and quality control.

The short-term blend combines PDSI, Z-Index, 1-month SPI, and 3-month SPI to estimate the overall short-term drought. Please refer to the product documentation for more information. This product is an example of current NIDIS-funded research.

This data is updated every 5 days, with a delay of 4 to 5 days to allow for data collection and quality control.

* Currently, data is only available for the contiguous U.S.

The U.S. Geological Survey (USGS) produces maps of real-time streamflow conditions compared to historical conditions. The map depicts streamflow conditions as computed at USGS streamgages. The colors represent real-time streamflow compared to percentiles of historical daily streamflow for the day of the year. Click on a streamgage to view more data for that location. Learn more.

The National Weather Service (NWS) Climate Prediction Center (CPC) produces precipitation outlooks for the U.S., including 6-10 day, 8-14 day, monthly, and seasonal outlooks. This 1-month outlook depicts whether there is a greater chance for above-normal, below-normal, or near-normal precipitation conditions in this region. Learn more.

This map shows the Center for Disease Control and Prevention's (CDC's) Social Vulnerability Index alongside current U.S. Drought Monitor drought designations. CDC's Social Vulnerability Index uses 15 U.S. census variables at tract level (including poverty, lack of vehicle access, and crowded housing) to help local officials identify communities that may need support in preparing for or recovering from hazards, like drought.

Evaporative Demand (EDDI)
EXPERIMENTAL

The Evaporative Demand Drought Index (EDDI) is an experimental drought monitoring tool that can serve as an indicator of both rapidly evolving "flash" droughts and sustained droughts. It examines how anomalous the atmospheric evaporative demand (E0; also known as "the thirst of the atmosphere") is for a given location and across a time period of interest. Learn more.

CPC Outlooks

NOAA's Climate Prediction Center issues Monthly and Seasonal Drought Outlooks each month. The Monthly Drought Outlook predicts whether drought will emerge, stay the same, or get better over the next 30 days or so, while the Seasonal Drought Outlook predicts whether drought will emerge, stay the same, or get better in the next three months.

Historical Conditions for Grand County

    The U.S. Drought Monitor (USDM) is a national map released every Thursday, showing parts of the U.S. that are in drought. The USDM relies on drought experts to synthesize the best available data and work with local observers to interpret the information. The USDM also incorporates ground truthing and information about how drought is affecting people, via a network of more than 450 observers across the country, including state climatologists, National Weather Service staff, Extension agents, and hydrologists. Learn more.

    The Standardized Precipitation Index (SPI) is an index to characterize meteorological drought on a range of timescales, ranging from 1 to 72 months. The SPI is the number of standard deviations that observed cumulative precipitation deviates from the climatological average. NOAA's National Centers for Environmental Information produce the 9-month SPI values below on a monthly basis, going back to 1895. Learn more.

    Tree-rings are used to extend the instrumental record of drought to over 2000 years. The Living Blended Drought Product (LBDP) is a recalibrated data series of June-July-August Palmer Modified Drought Index (PMDI) values in the lower 48 U.S. states. This dataset blends tree-ring reconstructions and instrumental data to estimate the average summer PMDI values, which extend over 2000 years in some parts of the U.S. Learn more.
