Pendleton, Oregon – Triple-digit heat is gripping north-central Oregon and southeastern Washington, with temperatures nearing 103°F and little overnight relief expected through Tuesday evening.
According to the National Weather Service in Pendleton, a Heat Advisory remains in effect until 9 p.m. Tuesday for the Columbia Basin, Yakima Valley, and foothills of the Blue Mountains.
