A FLOOD ADVISORY is in effect for a lot of the Hi-Line east of I-15 until 12pm/6pm Friday. Flooding due to snowmelt is currently occurring in these areas.
Flooding will continue to be an issue along the Hi-Line for the foreseeable future as the rain and snow that we have received over the past couple of days will continue to runoff into the rivers/creeks/streams that are already running higher than usual. If there is water on the roadways, make sure you turn around and don’t drown.
There are going to be areas of light to moderate snow around tonight and tomorrow as a storm system hangs out near our area. In the lower elevations, up to 6 inches of new snow accumulation is possible, and in the mountains, up to 12 inches of new snow accumulation is possible, with isolated higher amounts. The highest snow amounts tonight into tomorrow are likely going to be along the Rocky Mountain Front and in Cascade, Fergus, and Judith Basin Counties. Roads are also going to be slick and/or snow-covered in some areas tonight and tomorrow, so please use caution when driving and give yourself some extra time to get to where you need to go.
