The Puget Sound region is bracing for a sustained marine layer, a typical spring weather pattern characterized by cooler temperatures and overcast skies. This phenomenon occurs as moist Pacific air interacts with the region's cooler land temperatures, resulting in low-lying clouds and fog that significantly reduce visibility, particularly in the mornings. Residents can anticipate a damp and chilly atmosphere during this period. Meteorological observations indicate that the marine layer is expected to persist for several days, with gradual clearing in the afternoons as the sun warms the surface and dissipates the fog.
