RRV Flooding
March 21, 2013
More snow plus a delayed thaw equals an increased risk of flooding throughout the Red River Valley. The National Weather Service and River Forecast Center say recent storms have added substantially to the snowpack and water content basin-wide. As a result there is a high risk of major flooding is anticipated at Wahpeton… Fargo… Halstad…Oslo…and Pembina. Moderate flooding can be expected at Grand Forks and Drayton. Minor flooding is forecast for Crookston…Alvarao…and Roseau.
Overall temps are expected to remain below seasonal norms through early next week and precip amounts lower than normal. A more active weather pattern could develop in early April. The best guess for a crest in Greater Grand Forks (50-50) is around 46 feet.
