HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE MISSOULA MT
1048 AM MST SAT FEB 7 2015

...Periods of Heavy Rain through the Weekend...

Several disturbances are interacting with subtropical moisture
streaming across the region causing precipitation continuing
through the weekend. Snow levels are above 6,000 feet and will
remain high through the weekend. Rainfall amounts will generally
range from 1-3 inches but isolated totals over 4 inches will be
possible, especially for the northern Clearwater Mountains, as
well as the Cabinet and Whitefish Ranges. Potential impacts are
stated below:

In Idaho, rock and mudslides are possible along Highways 11, 12,
14, and 95. Rain and rain falling on snow will likely lead to
rapid rises in small streams and rivers, but none are forecast to
exceed bankfull at this point.

Across northwest Montana, rock and mudslides are possible along
Highways 2, 135, 200, and along I-90 west of Missoula. Rain and
rain falling on snow will likely lead to rapid rises in small
streams and rivers, but none are forecast to exceed bankfull at
this point. Around the Glacier Park region and in the Flathead
Valley, rain on existing snowpack may lead to significant ponding
and poor runoff.

This is a changeable situation, so those along streams and rivers
or in potentially impacted areas should be aware of future
outlooks, watches, or warnings from the National Weather Service.
