High Wind in Central Black Hills, South Dakota

An intense low pressure system slowly crossed the region, bringing a prolonged period of very strong northwesterly winds. A tight pressure gradient remained across the Northern Plains, with 36 hours of strong winds over much of the western South Dakota plains. Gusts of 60 to 80 mph were reported across much of the area, with a few higher gusts from Buffalo to the Rapid City area. Some minor damage resulted with isolated power outages and tractor trailers were tipped over on Interstate 90.
