FARGO — Periodic showers continue to drench the Red River Valley, where widespread heavy rain fell the night of Monday, July 8, dumping 4.2 inches on Hallock, Minn., and 2.25 inches on Fargo as of Tuesday morning.
In North Dakota, Harwood received 3.27 inches and Mayville 2.52 inches, according to reports compiled by the National Weather Service. In Minnesota, north Moorhead received 3.03 inches, Georgetown 3.25 inches, Baudette 2.52 inches and Thief River Falls 2.3 inches.
"There's quite a range," Brad Hopkins, a weather service meteorologist, said Tuesday morning. "We haven't completed all the storm reports yet."
The weather service predicts another half inch to 1.5 inches of rain will fall Tuesday into Tuesday night, ending Wednesday, with heavier amounts possible near the Canadian border.
"There's more precipitation that's moving up from the south," a system that includes embedded thunderstorms, where heavier amounts are possible, Hopkins said.
Most storm reports are from heavy rain, but a storm chaser reported a wind gust of 70 mph about 9 p.m. Monday, according to the weather service.
The heaviest rain in North Dakota was in Linton, south of Bismarck, where 5.58 inches was reported, said Lydia Blume, a WDAY meteorologist.
"It's been pouring and pouring and pouring there," she said. "That's a lot of rain."
Fargo will continue to see periodic rain showers, tapering off early Wednesday, she said. "Wednesday afternoon looks to be dry," Blume said.
With the latest rains, Fargo likely is now well above average in annual precipitation. As of Monday, Fargo had received 11.58 inches of precipitation, slightly above the 11.56 inches considered normal for the date. Before Monday's heavy rain, Fargo had received 0.18 inches of rain in July.
The heavy rain prompted the National Weather Service to issue a flood warning on the Red River in Fargo-Moorhead and the Buffalo River in Clay County. As of late Tuesday afternoon, the river was at 18.9 feet, in minor flood stage.
The Red River in Fargo-Moorhead is expected to crest at 19.3 feet Friday evening. At 19 feet, the low-level dam south of Main Avenue in Fargo is closed.
Minor flooding on the Red River in Fargo-Moorhead starts at 18 feet.
The Red River briefly surged after Monday night's heavy rain, rising from slightly less than 17 feet to 17.49 feet, according to the National Weather Service. By Tuesday morning, the level had dropped back to 17.1 feet, but soon will rebound and continue rising through Sunday evening.
