Hydrologic Outlook
National Weather Service Spokane WA
230 PM PDT Fri Apr 6 2018

...Rain and snowmelt will result in significant rises on river and
streams this weekend and into early next week...

The region`s warm and wet weather pattern will resume on Saturday.
Signifant amounts of rain and rising snow levels are expected, with
upper elevation snowmelt increasing rapidly. The combination of rain
and snowmelt will cause rises on rivers and streams this weekend and
persisting through at least early next week. There is also the
potential for rockslides and small landslides on steep slopes and
localized flooding in low lying areas with poor drainage.

At this time no rivers are forecast to reach flood stage, but
significant rises are expected in the Spokane, Palouse, Clearwater
and Lower Snake River basins. Additionally, small creeks and streams
that feed these rivers are expected to see significant rises. Minor
flooding and ponding of water may occur along small streams, creeks,
and ditches, particularly where snow, ice, or debris are blocking
drainage paths.

Forecast rainfall amounts Saturday through Monday will range from
one-half to one-and-one-half inch across the Idaho Panhandle, north
central and eastern Washington and the east slopes of the Cascades.

This is an evolving weather event, so those that could be
impacted should monitor the latest weather forecasts closely and
check for forecast updates and flood watches and warnings.
