DICKINSON (AP) - Gov. John Hoeven has deployed 40 National Guard soldiers to Dickinson, where cleanup is under way after a storm that destroyed houses, flipped vehicles, uprooted 70-foot trees and knocked out power in some parts of the city.

Hoeven also was traveling to Dickinson today.

Some residents say the Wednesday night storm produced two tornadoes. National Weather Service meteorologist Patrick Ayd in Bismarck says a damage assessment team is being sent to the city to make an official determination.

Police Lt. Rod Banyai said authorities know of no major injuries in the city of about 16,000.

To the north, an oil field company's storage building southwest of Williston was demolished, either by a tornado or strong winds.

The Weather Service says tornado touchdowns and strong winds also were reported in several other areas. There were reports of grain bin damage near Glen Ullin in Morton County. In northern Burke County, there were reports of downed power lines, damaged oil storage tanks, a destroyed barn and a destroyed granary.
