Ray Nieuwsma, mayor of Strasburg, N.D., said heavy rain started about 8 p.m. Monday and continued steadily until after midnight in the town of 376 people.
"It's wet," he said Tuesday. "We've got a few pumps going around town. The low areas have a little bit of a mess."
Nieuwsma said local rain gauges were reporting 5 to 6 inches of rain in the four-hour period.
"They didn't get a break," said Mary Senger, emergency manager for Emmons and Burleigh counties. "It just kept coming and coming."
The National Weather Service reported 5 inches of rain at Strasburg, according to Bill Abeling, a meteorologist with the Weather Service in Bismarck.
"The line (of storms) moved east with one storm after another passing over some areas," he said. "... It looked like it was stationary but was actually multiple storms moving through the area."
Abeling described the movement of the weather systems as "chaining," as a chain of multiple storms hit the same area in rapid succession.
Other reports from Emmons County included 5.5 inches of rain at Linton and 3.3 inches at Temvik, according to NWS storm reports.
Senger said there were reports of brief street flooding in Linton and crop damage due to the intensity of the rain in the Hazelton area.
When the storm ultimately moved east, it continued to bring heavy rain. The NWS reported 2.9 inches at Wishek, 2.4 inches at Napoleon, 2.2 inches at Gackle and 2.4 inches at Merricourt.
The rains in Dickey and LaMoure counties compounded previous wet conditions.
"Parts of LaMoure County had 3 and a half to 4 inches on July 3," said Kimberly Robbins, LaMoure County emergency manager. "They added 2 inches to that last night."
Robbins said the area south of the city of LaMoure to the county line has been the hardest hit this past week.
"As far as we know the county roads are OK," she said. "But there are reports of township roads being underwater again."
The NWS issued a small stream flood advisory for LaMoure County until 3 p.m. Wednesday. The advisory warned motorists not to drive into flooded areas of roads.
In Fullerton, N.D., in central Dickey County, the rain resulted in street flooding, according to Charlie Russell, Dickey County emergency manager.
"It just won't quit," he said, regarding continuing rain in the area after a winter of more than average snow. "... Depending whose rain gauge you believe, they've had 7 to 8 inches of rain in the last three to four weeks."
While heavy rain was the principal hazard of the storm system as it passed south of Jamestown, winds of up to 56 mph were reported at Arrowwood National Wildlife Refuge at Edmunds and 60 mph at Cooperstown.
Jerry Bergquist, Stutsman County emergency manager, said the northern edge of the county was included in two severe thunderstorm warnings but the bulk of warning area and the bad weather passed around Stutsman County.
The Jamestown area received about 1.8 inches of rain Monday evening through Tuesday at noon. The peak wind gust reported at Jamestown was 39 mph between 6 p.m. and 7 p.m. Monday. There were no reports of damage or flooding in Stutsman County, Bergquist said.
