A slow moving cluster of very powerful thunderstorms produced 3 to 6 inches of rain over parts of southeast North Dakota early Thursday June 20th. Based on preliminary RADAR and observer reports, 5.30 inches of rain fell at the Gwinner Airport overnight.
Floodwaters in Gwinner have swamped streets and buildings including the Bobcat Co. plant. City Auditor Jessica Peterson tells The Associated Press that a lot of basements are "completely full" of water, and the town's sewer system also has been overwhelmed.
At least one person has died in flash flooding.
The threat for strong to severe thunderstorms is expected to develop Thursday afternoon and persist Thursday night. The main threats should be large hail and damaging winds.
