Residents along creeks and rivers in Kittitas and Yakima counties should be aware of rising water resulting from predicted heavy rain along the east slopes of the Cascades this week. The National Weather Service forecasts up to three inches of rain for the mountains through Tuesday night. Residents should be alert for rapidly changing conditions.

The threat of flash flooding near Mission Creek, No. 1 and No. 2 Canyons above Wenatchee, Highway 97 below the Byrd Canyon Fire, Crum Canyon up the Entiat River, and First Creek above Lake Chelan State Park is extremely high because of steep terrain in the burned area.

The Wenatchee World reported that a flash-flood advisory is posted for all of Chelan and Douglas counties and western Douglas County because of the predicted storm that could produce as much as 3 inches of rain in lower elevations and 6 inches in the Cascades.

The advisory will be in effect from Monday evening through Wednesday evening and covers the eastern slopes of the Cascades. The NWS said that 1 to 3 inches of rain will inundate already saturated soils and could cause flooding, mudslides, and debris flows on and near areas burned by wildfire. Streams and creeks will see quick rises as early as tonight, and the White River and Nason Creek near Plain are of particular concern.
