The mountain ranges greatly affect the weather and wind patterns. Most of the precipitation and wind patterns depend on the surrounding mountains.
The changes in the climate are so severe that it's causing the animals to have difficulties.
It's famous for record breaking precipitation. The seasonal changes in the moisture means the laden air collides with Olympic and Cascade mountains creating rain to fall down the mountains.
The climate changes depend on the Aleutian Low Pressure Pattern. An intense Aleutian Low means relatively warm and dry winters. A weak Aleutian Low means a cooler and wetter winter.
Mostly consists of large scale wind patterns and weather changes.
