Spring Outlook: Risk of major flooding in North Dakota, moderate flooding in Idaho

Northern North Dakota – the Souris River, Devils Lake and the northernmost reaches of the Red River – has the greatest risk of major flooding this spring, while moderate flooding is possible over southern Idaho in the Snake River basin, according to NOAA’s Spring Outlook released today.

California, which saw extensive flooding in February, is susceptible to additional flooding from possible storms through the remainder of the wet season and later, from snowmelt.

“If you’re in northern North Dakota, or in the Snake River basin in Idaho, prepare for moderate to major flooding this spring,” said Tom Graziano, Ph.D., director of NOAA’s Office of Water Prediction. “Snowpack is heavy in the West and northern plains, and if our long term warm-up coincides with spring rains, already saturated soils will not be able to absorb the increased water, which would lead to increased runoff and potential flooding.”

But while the extreme north could see flooding, the rest of the country could be warmer than average, forecasters said. “Above average temperatures are favored for much of the U.S. this spring with the south-central Plains and eastern U.S. having the highest chance for warmer than average conditions,” said Jon Gottschalck, chief, Operational Prediction Branch, NOAA’s Climate Prediction Center.
