2023 Spring Flood Outlook
NOAA issued its three-month U.S. Spring Outlook today.
According to the agency:
There is a risk for flooding in most of the eastern half of the continental United States, including most of the Mississippi River Basin. Forecasters with the National Water Center, in concert with NWS River Forecast Centers, predict moderate to major flooding along the Mississippi River from Minneapolis, Minnesota, to St. Louis, Missouri.
An above normal to record snowpack in the Sierra Nevada mountains, combined with elevated soil moisture, increases the threat of spring flooding due to snowmelt, especially at high elevations.
"Approximately 44% of the U.S. is at risk for flooding this spring,” said Ed Clark, director of NOAA’s National Water Center. “California’s historic snowpack, coupled with spring rain, is heightening the potential for spring floods.”
Spring snowmelt will bring welcomed water supply benefits to much of California and the Great Basin. Reservoirs in the Colorado River Basin, such as Lake Powell and Lake Mead, are currently at record low water levels following years of drought.
