Flood Outlook

Feb 21, 2013 at 12:55 pm

Recent storms have raised snowpack levels in the Red River Valley increasing the risk of Spring flooding.   Most of the additional snow and associated water equivalent is located in the southern part of the basin and further north near the Canadian border.   Greg Gust of the NWS office in Grand Forks says the risk of moderate to major flooding is on the rise.  Fargo has a 79-percent chance of major flooding while Grand Forks / East Grand Forks sits at six-percent.    Gust says there are some positives in that river flows remain low.  The best guess crest for Grand Forks  is around 39 feet.  fFood stage is 28.
