The February 13, 1979, windstorm was a natural phenomenon which happened in the West Coast region of Canada and the Pacific Northwest. During the early morning, an intense wave cyclone moved across southern Vancouver Island in British Columbia. South of the low center, a strong atmospheric pressure gradient was carried across Washington, with associated high winds. With a cold airflow moving toward the northeast interacting with the high terrain of the Olympic Mountains, a lee low developed east of the Olympics. The mesoscale low caused a particularly intense pressure gradient across the Kitsap Peninsula region.
