Aereal Flood Advisory
... The Flood Advisory for melting snow remains in effect until 415 PM MDT Saturday for Gallatin... Judith Basin and the eastern and southern portions of Cascade counties...
Snow melt from higher elevations will allow small streams and creeks flowing out of the mountains to continue to generally rise over the next few days. Expect the creeks to rise during the afternoon and evening hours because of increased snowmelt... with creek levels slowly leveling off or slightly decreasing during the overnight hours. This pattern of snow melting can be expected to continue through Saturday.
In Judith Basin County... Ross Fork creek is out of its bank in places... while Otter Creek and Willow Creek are near bankful in several places and minor flooding is possible at any time along these creeks.
In Cascade County... Sand Coulee creek is out of its bank in places. In Gallatin County... minor low land flooding is occurring along small streams flowing out of the mountains.At 400 PM MDT continuing snowmelt combined with ongoing rainfall is causing streams and creeks across Gallatin County to rise. With precipitation expected to continue through the night... and mild temperatures helping mountain snow continue to melt... localized flooding is possible in some locations. Conditions will be monitored for the possibility of issuing further hydrologic highlights.
