Portland (Oregon) is a city in northwestern Oregon, the seat of Multnomah County and the largest city in the state. Portland is the business and transportation hub for much of the Pacific Northwest as well as a growing center for electronics manufacturing. The city has an eye-catching natural environment and abundant cultural resources; it represents itself as the City of Roses.
Portland lies on both banks of the Willamette River around where it empties into the Columbia River. Summer and spring weather is generally mild, and the city receives heavy rains during the late fall and winter. Whilst heavy snow is rare, Portland sometimes suffers under ice storms caused when frigid air on the state's interior passes throughout the gorge of the Columbia River and collides with the warmer, moist air of the coast. Average annual precipitation is 920 mm (36 in). In January the average high temperature is 7° C (45° F) and the average low 1° C (34° F); in July highs average 27° C (80° F) and lows 13° C (56° F).
Francis Petty grove, one of the founders of Portland, named the city around 1845 after winning a coin toss together with cofounder Asa Lovejoy. Petty grove named it for his hometown of Portland, Maine; had Lovejoy won he intended to name it after his hometown of Boston, Massachusetts.
