Current Conditions for Summit County

The U.S. Drought Monitor (USDM) is updated each Thursday to show the location and intensity of drought across the country using a five-category system, from Abnormally Dry (D0) conditions to Exceptional Drought (D4). The USDM is a joint effort of the National Drought Mitigation Center, USDA, and NOAA. Learn more.

The 30-day departure from normal temperature shows the difference of the last 30 days from the usual conditions for the same time period averaged since 1980.

This map uses the gridMET and PRISM temperature datasets, which are delayed from the current day by 2 to 3 days to allow for data collection and quality control.

The 30-day percent of normal precipitation shows the difference of the last 30 days from the usual conditions for the same time period averaged since 1980.

This map uses the gridMET and NLDAS precipitation datasets, which are delayed from the current day by 2 to 3 days to allow for data collection and quality control.

Short-Term Drought Indicator Blend

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 long-term blend combines PDSI, Z-Index, and 6-month, 1-year, 2-year, and 5-year SPI to estimate the overall long-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.

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) Forecast

The Evaporative Demand Drought Index (EDDI) is an experimental drought monitoring and early warning guidance tool. 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. This experimental subseasonal EDDI forecast shows projected evaporative demand for the next 2 weeks and 4 weeks from the CFS-gridMET dataset at 4-km gridded resolution. 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.

The Seasonal Drought Outlook predicts whether drought will emerge, stay the same, or get better in the next three months.

Historical Conditions for Summit 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.
