The climate

Seattle's temperate, rainy climate is usually described as temperate Oceanic or Marine west coast, with mild, wet winters and mild, relatively dry summers. The Puget Sound Convergence Zone is an important feature of Seattle's weather. In the convergence zone, air arriving from the north meets air flowing in from the south. Both streams of air originate over the Pacific Ocean; airflow is split by the Olympic Mountains to Seattle's west, then reunited by the Cascade Mountains to the east. When the air currents meet, they are forced upward, resulting in convection.Thunderstorms caused by this activity can occur north and south of town, but Seattle itself rarely receives worse weather than occasional thunder and ice-pellet showers. The Hanukkah Eve Wind Storm in December 2006 is an exception that brought heavy rain and winds gusting up to 69 mph (111 km/h).
