North American snow cover – Red River flood risk

(republished from commodityweather)
The first map below from the Rutgers Snow Cover Lab shows the Northern Hemisphere snow cover anomalies for March 2011.  The second map shows the daily anomaly from yesterday (6 Apr).  We highlight this because the risk of flooding from snowmelt runoff, particularly in the Red River Valley region (MN/ND) is high given the snowpack distribution and the temperatureprecipitation forecast for the next several days.

At Fargo, major flood stage for the Red River is 30.0 feet.  Shown below is the Weather Service forecast for river levels over the next 7 days, followed by the WeatherTrends360 forecast:
