A tornado warning has been issued in northeastern North Dakota as a storm system with funnel clouds heads towards the Minnesota border.
The National Weather Service issued the warning for Grand Forks and Walsh counties at lunchtime, with a report that a funnel cloud has been spotted west of the Grand Forks air base.
And it looks like one has touched down near Hatton, North Dakota, if the insane Twitter video below is anything to go by.
The NWS confirmed that tornadoes have been reported, and has identified a funnel cloud "risk area" through 2:30 p.m. that includes a large area of northwestern Minnesota.
In a special weather statement updated at around 1:40 p.m., the NWS says funnel clouds are a possibility across the whole Red River Valley for the next few hours, covering Minnesota cities including Red Lake Falls, East Grand Forks, Warroad, Bemidji and Mahnomen.
Those in the area are being advised to stay close to shelter.
