Flooding is expected to begin shortly, especially near The Mendenhall Lake And River. - The outburst flood forecast is based on an estimated volume of water in the glacier dammed lake and an estimated release rate based on previous events. The extent of water drainage within the basin (partial or full) can vary widely between outburst flood events and is a major source of uncertainty in the forecast, particularly with regard to the peak flood stage. - For Mendenhall Lake : At 2:00pm the stage was 6.2 feet. Flood Stage is 9.0 feet. Forecast: A crest around 9.8 to 10.3 feet is expected between 5 to 9am Friday. Water levels will go above minor flood stage of 9 feet around 2am Friday. Water levels will reach moderate flood stage of 10 feet around 5 to 9am Friday. Water levels will fall below minor flood stage late morning Friday. Impacts: At 6.7 feet: Nugget Falls trail begins to flood near the "causeway" at the end of the trail. At 7.7 feet: Nugget Falls trail begins to flood near the beginning of the trail. Along the Mendenhall River some sections will experience bank erosion resulting in dangerous tree fall. These conditions could make floating the river more hazardous with the higher water levels. At 9.0 feet: Water starts to cover Skaters Cabin Road between Skaters Cabin and West Glacier Trailhead, also water will flow into the Mendenhall Lake Campground. At 9.5 feet: Water levels up to 0.5 feet will cover Skaters Cabin Road between Skaters Cabin and West Glacier Trailhead. Campsite 7 will be flooded with water starting to flow over the road between campsites 8 and 9 in the Mendenhall Campground.

What the agency told people to do
Stay tuned to further developments by listening to your local radio, television, or NOAA Weather Radio for further information. Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. The cold water temperatures can increase the threat of hypothermia and lower the time required to cause hypothermia.
