The barometric pressure in Ketchikan, Alaska is influenced by its coastal location. The city's proximity to the Pacific Ocean means that pressure systems from the west impact the area. These systems can bring changes in pressure quickly. Rapid pressure changes can lead to shifting weather patterns.
Ketchikan is surrounded by mountains to the east and water to the west. The Tongass Narrows, a narrow saltwater channel, borders the city. The Coast Mountains tower above the city, reaching elevations over 5,000 feet. The unique landscape of Ketchikan guides airflow and alters the atmospheric pressure. The mountains force air upwards, cooling it, and resulting in precipitation.
