Cape Cod is currently experiencing dense fog along its coastal areas, significantly reducing visibility and impacting transportation and outdoor activities. The fog is a result of moist air meeting cooler ocean waters, leading to condensation. This creates hazardous conditions for drivers, boaters, and pedestrians, with visibility potentially dropping to near zero in some areas. Authorities are advising motorists to reduce speed and increase following distances, while boaters are urged to use navigational tools and consider postponing trips. Pedestrians should also exercise caution and ensure they are visible to drivers.
