Residents in Fargo, N.D., are preparing for major flooding this weekend. The Red River is expected to crest sometime Sunday.
The community joined together to build walls of sandbags -- more than a million bags so far. Just last year, the city faced their worse flooding in history.
The rising Red River is causing agriculture concerns across the country. This area provides much of the nations winter wheat.
Government relief teams are already in the area preparing for the worst.
"They're bringing in communication towers with repeaters," said Greg Wilz of the North Dakota Department of Emergency Services. "They can instantly set up these repeaters and tie in the search and rescue helicopters with the search and rescue boats back to com centers that the state has."
Most of the relief crews worked last year's floods in the state. They say this time they are ready.
