SPOKANE, Wash. -

Forecasters are warning of wildfire danger Wednesday in southeast Washington and northeast Oregon due to a combination of winds and low humidity.

A red flag warning is in effect until 9 p.m. for the area from Yakima through the Tri-Cities to Walla Walla in Washington and including The Dalles, Hermiston and Pendleton in Oregon.

The National Weather Service says humidity will be as low as 13 percent and winds of 10-to-20 mph with gusts to 35 mph are forecast.

Forecasters say temperatures east of the Cascades will be in the mid-80s to low 90s the next few days, and morning clouds west of the Cascades will provide some relief from summer heat, with highs in the 70s.
