Puget Sound Convergence Zone Puget Sound Convergence Zone The Puget Sound Convergence Zone (PSCZ) is a meteorological phenomenon that occurs over Puget Sound in the U.S. state of Washington. It is formed when the large-scale air flow splits around the Olympic Mountains and then converges over Puget Sound. This convergence zone generally occurs between north Seattle and Everett and can cause updrafts and convection, which leads to a narrow band of precipitation. A second, weaker convergence zone can occur between approximately Victoria, British Columbia, and Bellingham, Washington, over the San Juan Islands, as a result of southwesterly air blowing from the Strait of Juan
Puget Sound mosquito fleet Puget Sound mosquito fleet The Puget Sound mosquito fleet was a large number of private transportation companies running smaller passenger and freight boats on Puget Sound and nearby waterways and rivers. This large group of steamers and sternwheelers plied the waters of Puget Sound, stopping at every waterfront dock. The historical period defining the beginning and end of the mosquito fleet is ambiguous, but the peak of activity occurred between the First and Second World Wars. Puget Sound and the many adjacent waterways, inlets, and bays form a natural transportation route for much of the western part of Washington. For
