Like the arteries that supply blood to the heart -- the coronary arteries -- the carotid arteries can also develop atherosclerosis or âhardening of the arteriesâ on the inside of the vessels. Over time, the buildup of fatty substances and cholesterol narrows the carotid arteries.
NPS/Steve Redman. Weather patterns at Mount Rainier are strongly influenced by the Pacific Ocean, elevation, and latitude. The climate is generally cool and rainy, with summer highs in the 60s and 70s. While July and August are the sunniest months of the year, rain is possible any day, and very likely in spring, fall, and winter.
The climate, like most of the Oregon west of the Cascades, is marine with significant winter precipitation and clouds. Summers are usually warm, dry, and pleasant, with temperatures in the 70âs or low 80âs; one annual hot spell usually raises temperatures to about 100 degrees. Summer rains are infrequent.
