Areas of dense fog have been observed through the Walla Walla Valley and along the Blue Mountain foothills. Within fog, visibilities of one- quarter mile or less are expected to persist locally through the afternoon along Highway 12 and along the Oregon Washington Highway. Use extra caution while traveling as visibilities can change quickly. If fog is encountered, use low- beam headlights and keep plenty of space between you and other vehicles.
