Up to 4 inches of rainfall is expected to hit western Montana over the next three days, prompting a flood warning from local emergency service officials.
A steady stream of precipitation will punch into the Northern Rockies through Wednesday, causing moderate to heavy rainfall to impact north central Idaho and western Montana, the National Weather Service said in an announcement Monday. The region could also experience strong winds gusting up to 40 miles per hour.
Several inches of rain will accumulate during this time, causing various impacts. Rock and mudslides may also occur, affecting highways. In addition, low-lying areas could see standing water. Small streams could also rise significantly, causing localized flooding. Snow levels will be rising to roughly 7000 feet, keeping midslopes warm enough to cause rain to fall and existing snow to melt.
The Flathead Office of Emergency Services issued a flood watch through Wednesday. In some instances, creeks could become clogged with leftover ice, which could lead to localized flooding.
A flood watch means there is a potential for flooding based on current forecasts.
