Watches & Warnings

Areal Flood Watch
Issued: 12:51 PM PST Jan. 17, 2017 – National Weather Service

... Flood Watch in effect from Wednesday morning through late
Thursday night...

The National Weather Service in Spokane has issued a

* Flood Watch for portions of Idaho and Washington, including the
following areas in Idaho, central Panhandle mountains, Coeur
D'Alene area, Idaho Palouse, Lewis and southern Nez Perce
counties, Lewiston area, and northern Panhandle. In Washington,
lower Garfield and Asotin counties, Moses Lake area, northeast
Blue Mountains, northeast mountains, Okanogan Valley, Spokane
area, upper Columbia Basin, Washington Palouse, and Waterville
Plateau.

* From Wednesday morning through late Thursday night

* a period of moderate to heavy rain will arrive Tuesday night,
last through Thursday night, and will be accompanied by above
freezing temperatures. With widespread mid and low elevation
snow, the resulting runoff from rainfall and snowmelt may be
enough to cause localized flooding issues. Flooding may be
exacerbated in areas where storm drains and ditches are clogged
with snow and ice or where soils are frozen. Ice jams on frozen
rivers and creeks are also a possibility with this event.

* Most likely impacts from this event include flooded roads and
urban areas where ditches and storm drains are clogged with
snow, ponding water in low lying areas with poor drainage or
frozen ground, sharp rises on small creeks and streams, and ice
jams on creeks and rivers.


Precautionary/preparedness actions...

A Flood Watch means that flooding is possible but not imminent in
the watch area. You should monitor forecasts, be alert for
possible flood warnings, and maintain awareness of local
conditions. Those living in areas prone to flooding should be
prepared to take action should flooding develop. Report any ice
jams to local emergency management or law enforcement.
