Current Conditions for Orange 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.

This map shows the departure from normal maximum temperature  (°F) over the past 30 days, compared to usual conditions for the same time period averaged from 1991–2020.

This map uses the gridMET and PRISM temperature datasets. Temperature data are updated daily, with a delay of 3 to 4 days to allow for data collection and quality control. Learn more.

This map shows the percent of normal precipitation for the past 30 days, compared to the usual conditions for the same time period averaged from 1991–2020.

This map uses the gridMET and NLDAS precipitation datasets, and precipitation data are updated daily, with a delay of 3 to 4 days. Learn more.

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

The data are updated every 5 days, with a delay of 4 to 5 days to allow for data collection and quality control. Learn more.

Long-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 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. This product is an example of current NIDIS-funded research

The data are updated every 5 days, with a delay of 4 to 5 days to allow for data collection and quality control. Learn more.

Agriculture in Orange County

The USDA's National Agricultural Statistics Service (NASS) conducts hundreds of surveys every year and prepares reports covering virtually every aspect of U.S. agriculture, including agricultural commodities statistics for crops and livestock. This map displays crops and livestock by county alongside the current U.S. Drought Monitor. The size of each dot represents the total acres (crops) or total inventory (livestock) per county. Learn more.

Water Supply in Orange County

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) 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.

Historical Conditions for Orange 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.
