Parched March expands western drought conditions for third month in a row
Average precipitation in March was 2.26 inches (0.25 of an inch below average), ranking in the driest third of the climate record
For the third month in a row, precipitation was below average across the contiguous U.S., expanding western drought conditions and areas of record dryness.
According to NOAA’s U.S. climate report, March's average monthly temperature across the U.S. was 44.1 degrees, ranking in the warmest third of the 128-year climate record. Temperatures were warmer than average across much of the West, and from the Midwest to the East Coast.
SNOWFALL CONSIDERED CRUCIAL FOR LONG-TERM DROUGHT MITIGATION
Alaska also saw above-average temperatures across much of the state, with Anchorage and Talkeetna both reporting a top-10 warm March.
Record heat on March 26 set a new all-time March temperature records for Las Vegas (93 degrees) and Death Valley (104 degrees).
ONGOING 22-YEAR DROUGHT IN WESTERN US IS DRIEST PERIOD IN OVER 1,200 YEARS, STUDY FINDS
Average precipitation in March was 2.26 inches (0.25 of an inch below average), ranking in the driest third of the climate record, NOAA recorded.
On March 29, roughly 58% of the contiguous U.S. was in drought, down slightly from the beginning of the month, NOAA said. During March, the U.S. drought footprint reached 61%, the largest observed extent of drought since the fall of 2012.
MORE THAN 50% OF US IS IN DROUGHT AS DRY, WARM CONDITIONS CONTINUE AHEAD OF SPRING
Precipitation was below average across much of the West, northern and southern Plains, and from the Tennessee Valley to the Mid-Atlantic and parts of the Northeast.
According to NOAA, above-average precipitation fell from the central Plains to the Great Lakes, as well as across parts of the Deep South and Southeast. North Dakota saw its seventh-driest March on record, while Michigan had its eighth wettest.
Other notable drought events in March
- The current multi-year drought across the western U.S. is the most extensive and intense drought in the 22-year history of the U.S. Drought Monitor.
- Across some parts of the West, precipitation for the first three months of 2022 was at or near record-low levels.
- During March, drought coverage across the contiguous U.S. reached 61% — the largest observed extent of drought since fall of 2012.
With below-average snow cover and critically low reservoirs in some places, concerns are mounting that the western drought will continue to intensify and strain water supplies.
