Lower Mississippi Region Watershed Drought Information
The U.S. Drought Monitor (USDM) is updated each Thursday to show the location and intensity of drought across the country. This map shows the drought conditions of the Lower Mississippi Region watershed, 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 updated daily with a delay of 3 to 4 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 updated daily with a delay of 3 to 4 days to allow for data collection and quality control.

- Short-term dryness slowing planting, growth of crops.
- Some lingering water deficits
- Pastures or crops not fully recovered
- Some damage to crops, pastures
- Some water shortages developing
- Voluntary water-use restrictions requested
- Crop or pasture loss likely
- Water shortages common
- Water restrictions imposed
- Major crop/pasture losses
- Widespread water shortages or restrictions
- Exceptional and widespread crop/pasture losses
- Shortages of water creating water emergencies
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.

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 shows agricultural products alongside the current U.S. Drought Monitor. Learn more.

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.
