Record U.S. drought raises concerns about wildfires, water and food prices

More than 61% of the contiguous United States is in moderate to exceptional drought, and NOAA recorded its highest March drought index since 1895; experts say these conditions increase risks for wildfires, water shortages and agricultural impacts.

Drought conditions across the contiguous United States have reached record levels for this time of year, based on recent monitoring and climate data. The U.S. Drought Monitor shows more than 61% of the Lower 48 in moderate to exceptional drought, with much of the Southeast and large portions of the West affected. NOAA reported that its Palmer Drought Severity Index for March was the highest on record for that month, and March ranked among the driest months measured. Scientists and agencies are highlighting links to low snowpack, unusually high atmospheric moisture demand and above-normal temperatures. Key facts: - The U.S. Drought Monitor reports over 61% of the contiguous U.S. in moderate to exceptional drought, including about 97% of the Southeast and roughly two-thirds of the West. - NOAA's Palmer Drought Severity Index reached its highest March value since records began in 1895, and March was the third-driest month on record. - Experts reported exceptionally low mountain snowpack in parts of the West and an unusually high vapor pressure deficit, both of which reduce natural water storage and increase dryness. - The National Interagency Fire Center and meteorologists noted higher-than-normal potential for significant fires in parts of the Southwest later this spring, and analysts warned of possible impacts on crops and food prices. Summary: Elevated drought measurements point to increased risk for wildfire activity, tighter water supplies in affected basins, and potential strain on agriculture that could influence food prices. Scientists attribute the event to a combination of natural variability and long-term warming trends. Undetermined at this time.
