One factor that would help minimize the flood risk this Spring is a warming of soil temperatures in the Red River Valley. Greg Gust of the National Weather Service in Grand Forks says those temps are slowly climbing but not enough to capture a lot of the snowmelt runoff. Gust says it’s hard to warm the soil when there is so much snow on top of it. As a result the soil is not holding a lot of water.
Gust says evaporation can also be a factor but with our cool temps it only amounts to about a hundredth of an inch per day with full sun. He says that gets wiped out by one precipitation event. A new outlook model released this week suggests there is a 40-percent chance of Fargo seeing a record event this Spring. The Red River will likely reach a top five all-time crest in Greater Grand Forks.
