Dense fog cuts visibility across parts of eastern Washington

The National Weather Service issued dense-fog advisories across parts of eastern Washington, including the Lower Columbia Basin, the Blue Mountain foothills, and northeast Washington, with visibility in some areas falling to a quarter-mile or less. The warnings covered periods Thursday and overnight into Friday, with advisories generally ending by Friday morning; a separate advisory for the Kittitas Valley was cancelled. Forecasters also warned of gusty winds in the Blue Mountain foothills, which could make driving difficult, bring down tree limbs, and cause isolated power outages. Drivers were urged to slow down, use low-beam headlights, leave extra following distance, and pull over somewhere safe if visibility becomes extremely poor.
