A low-altitude cloud layer enveloped the western portions of Washington and Oregon states in the northwestern USA, imparting a characteristic autumnal atmosphere to these territories. The cloudiness settled densely over the lowland and coastal areas of the region, creating an overcast and muted landscape. At the same time, the mountain ranges located near the coast rose above the cloud cover and remained illuminated by the sun, towering above the thick blanket of clouds below. This phenomenon is frequently observed in this region during transitional seasons, when the temperature difference between the surface air layer and higher atmospheric layers contributes to the formation of persistent low-altitude clouds or fog. This creates a striking contrast between the fog-shrouded valleys and the clear, sun-bathed mountain peaks. Such meteorological conditions are typical for the coastal zones of the Pacific Northwest, where moist marine air interacts with the local terrain. The phenomenon poses no danger to residents and is rather aesthetic in nature, attracting the attention of nature enthusiasts and photographers, who appreciate such atmospheric landscapes.
