| Episode Narrative |
A Pacific low moved into the four corners region on the 17th and migrated northeast into the Dakotas through the 22nd, bringing a round of heavy precipitation aided by a tap of Gulf of Mexico moisture. Another system passed to the south on the 23rd and 24th, continuing the precipitation across the area. |
| Event Narrative |
Heavy rains of 3 to 5 inches in the Big Horn Mountains and Foothills caused area streams and creeks to rise and result in localized flooding. Small streams and creeks around Dayton were reported to be flooded. In addition, flooding was reported along the Tongue River and Little Goose Creek and on creeks in the Ranchester area resulting in the closing of some county roads. During the height of the heavy rainfall, Pass Creek Road, far northern Sheridan County near the Montana border, flooded and was eventually washed out. Several culverts were also reported as washed out. |
