The Pacific Northwest can sometimes receive violent windstorms that reach hurricane strength, but it is not subject to hurricanes like the East Coast. These regional storms are known as mid-latitude cyclones. The mid-latitudes, from 30˚ to 60˚ north, experience a large difference in temperature between the tropics to the south and the arctic to the north. These temperature differences provide the energy source for the storms. The mixing of cold and warm air can create an area of low pressure as a cold front overtakes a warm front.
Wind strength is measured in terms of sustained winds and gusts. Sustained winds are the speeds averaged over one minute near the surface of the earth. Gusts are the three to five second peaks that are often more than 25 – 50% stronger than the sustained winds. Gusts are often what cause the greatest damage.
Cascade Downslope Winds:
These storms are caused by a build-up of high pressure east of the Cascades. When a low pressure system moves into the Puget Lowlands, the dammed up air east of the mountains comes surging through the lower passes. Stampede Pass is the lowest pass in the region and the area immediately below it, Enumclaw, routines sees strong winds as a result. Occasionally, these winds push all the way to Puget Sound south of Seattle. During one of these events, Fife and Federal Way can be experiencing winds of 50 -60 miles per hour while in Seattle the wind speed is close to zero.
