Drought lingers in southern Plains and Southeast, expands in West and upper Midwest
For the first time in four years, no area of the country faces a high risk of major to record spring flooding, largely due to the limited winter snowfall, according to NOAA’s annual Spring Outlook, which forecasts the potential for flooding from April to June.
“We’re not forecasting a repeat of recent historic and prolonged flooding in the central and northern U.S., and that is a relief,” said Laura Furgione, deputy director, NOAA’s National Weather Service. “The severity of any flooding this year will be driven by rainfall more so than the melting of the current snowpack.”
The Ohio River basin including portions of Illinois, Indiana, and Kentucky, along with parts of Louisiana and Mississippi are the only areas with an above-normal risk of flooding as soil moisture and river levels are currently above normal. Additionally, odds favor above-average April rainfall for the Ohio River basin.
River and stream water levels are normal to below normal for most of the country and there is less snow pack than in previous years. As a result, there is a normal flood risk from the Northeast, through the mid-Atlantic, across most of the northern Plains and into the Northwest. However, heavy spring rainfall can lead to flooding at any time, even in areas where overall risk is considered at or even below normal. Drought outlook infographic | Full NOAA release
