...WARM WEATHER THIS WEEK TO CAUSE RISES ON RIVERS...

Much above average temperatures are expected across the Pacific
Northwest and southwest Canada from Tuesday through at least
Sunday. High temperatures in the lowlands of eastern Washington
and northern Idaho will likely reach the 70s Tuesday and
Wednesday. By Thursday and especially Friday, some spots will
eclipse 80 degrees. For next weekend temperatures will cool
some, but still remain above average for this time of the year.

With mountain snowpack well above average, the warm weather will
produce an influx of runoff into our rivers and streams. With
snowpack around 150 percent of normal, rivers fed by runoff from
British Columbia, the northern Washington Cascades and southern
Shoshone county will likely experience the largest rises late
this week and through next weekend. The St Joe, Moyie, Kettle,
Okanogan, and Stehekin Rivers are a few rivers that are expected
to make significant rises.
