Officials in Fargo, N.D., are planning an aerial assault on the Red River Sunday.
Helicopters will drop one-ton bags of sand in an effort to divert the river's violent current away from vulnerable sections of the levees protecting the city.
Early this morning, the river briefly breached a dike at a spot where the current is especially fast. City officials say the water rushed through, shooting 3 to 4 feet in the air at times and flooding a school campus.
Air Force Predator drones will also take part in the aerial efforts. Officials will use them to monitor water patterns and ice floes and direct ground crews accordingly.
While the Red River crested just after midnight Saturday, it remains more than 20 feet above flood stage and is expected to remain dangerously high for a week. Mayor Dennis Walaker says residents should expect more breaches, but vows the city will remain vigilant.
