The National Weather Service in Great Falls is cautioning about the potential for ice jams and flooding this week.
Recent cold temperatures will be replaced with mild, warmer temperatures across much of central and southwestern Montana this week, according to the service. Some areas could see high temperatures return into the upper 30s to low 40s by the end of the week.
The pattern will create the potential for ice jam flooding through much of the work week, and possibly into the weekend, the service said in a news release.
According to the NWS:
- Minor to isolated moderate flooding is possible for any ice jammed rivers.
- Rivers may become out of banks at times.
- Anyone outdoors should stay off of river ice as it will become weak, unstable, and unpredictable.
- In extreme cases, impacts to near river roads and structures are possible.
