A dense marine layer has enveloped the Puget Sound region, resulting in persistent fog and significantly reduced visibility. This atmospheric phenomenon is typical for the area, particularly during transitional seasons when cooler ocean air encounters warmer inland temperatures. The marine layer is characterized by a thick blanket of fog that can obscure visibility for drivers and mariners alike. Local meteorological reports indicate that the fog is expected to linger throughout the morning, gradually dissipating as the day progresses. The presence of this marine layer is a common occurrence in coastal regions, where the interaction between land and sea temperatures creates ideal conditions for fog formation.
