Only two paved roads go in and out of Oslo and both are now closed because of flooding, leaving residents of the tiny northwest Minnesota town nowhere to go until water levels recede.
The town of 323 people sits along the Red River about 25 miles north of Grand Forks, and on Saturday the river crested at 37.8 feet, just shy of the record 2009 level of 38.37 feet.
On Wednesday, the North Dakota Department of Transportation closed Hwy. 54 from Interstate 29 all the way to the Red River, and the Minnesota Department of Transportation has now shut down Hwy. 1 from the North Dakota border all the way through Oslo to the east of town.
On Friday, Marshall County Sheriff Jason Boman warned residents that roads in and out of town could soon be inaccessible, and right he was.
"You better decide if you're going to leave or not,” the sheriff said, via the Grand Forks Herald. “Because it's very possible the road could be closed."
In an update to the Grand Forks newspaper on Saturday, the mayor of Oslo said there are no emergency situations yet and that the Minnesota National Guard is in town monitoring the city's dike system.
The latest from the National Weather Service on Sunday morning says major flooding is forecast to continue in Oslo for at least the next seven days. The river is expected to fall to 37.4 feet by mid-morning Monday, which is noteworthy because Hwy. 1 becomes impassable at 37.5 feet.
