  may occur along the Logan River in Logan Canyon. Additionally,
  the confluence between the Logan River and the Blacksmith Fork
  River could flood the housing development along State Routes

HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE BILLINGS MT
211 PM MDT Sun May 28 2017

Temperatures are forecast to warm into the 80s across the lower
elevations by the middle of the week, and persist at least
through the end of the week. At the same time, overnight
temperatures in the mountains will struggle to fall below
freezing. This will lead to an increase in the snowmelt across
the high country.

With the increased snowmelt, flows will subsequently increase
across area waterways through the week. Minor flooding will be
possible along streams in the foothills, with main stem rivers
potentially approaching flood stage as well. At the very least,
these will likely be the highest flows for the main stem rivers so
far this spring season.

Those with interests near rivers and streams should be alert to
the rising water levels over the next several days, and take
appropriate measures to protect livestock and property.
