JAMESTOWN (AP) - Paul and Amanda Smith came home after a storm to find one of their unattached garages gone.

The walls and roof of the older building blew off during Wednesday night's rain and hail, with most of it landing in a heap a few feet away. One wall was tossed over a fence into a nearby pasture. Two vehicles and a small tractor parked nearby were left virtually untouched.

"I just can't understand it," Paul Smith said.

The damage may have been caused by straight-line winds, or possibly a tornado, said Deputy Elizabeth Kapp of the Stutsman County Sheriff's Office.

"There were funnel clouds spotted around the county," she said.

The Smith family was lucky that the storm did not damage another garage where more belongings are stored, Amanda said. Their home had only minor damage - a broken window and water in the living room.

Jamestown was hit with heavy rain about 5 p.m., said Lt. Robert Opp, the shift supervisor at the Law Enforcement Center in Jamestown. The viaduct in the city was closed for about half an hour due to flooding.

"There were streets flooded all over town," he said.

Power also was knocked out briefly, causing traffic signals to flash, he said.

A flash flood warning also was issued for western La-Moure and Logan counties, south of Stutsman County, where up to 5 inches of rain fell.

Some of the heaviest rain Wednesday was in Walsh County, where 5 inches was reported in Edinburg.

Bernice Flanagan, who runs the General Store, said her town of about 250 could handle the rain.

"We're not a river town," she said. "It (the water) just goes off and goes on the baseball diamond."

Walsh County Emergency Manager Brent Nelson said basement flooding was reported in Edinburg, but there were no major problems.

Nelson said the region had not had significant rainfall since mid-July.

"Most of the water is just sitting and soaking into the fields," he said. "As long as we can avoid some additional rains … hopefully we won't have any major problems."

Grand Forks reported about 3 inches of rain Wednesday that caused street flooding.
