Damp and unsettled weather that swept back into the Pacific Northwest at midweek will stick around and pack more of a punch this weekend.

The first in a parade of storms inundated the Northwest with abnormally cool and dreary conditions to end the week.

After a brief break from wet weather on Friday night, another powerful storm will affect the Northwest through Saturday night with a resurgence of rain and wind.

The bouts of steadier rain will make an umbrella a must for people venturing outside.

Regardless of rainfall, residents in the Northwest will need jackets, sweatshirts and even coats and scarfs if planning prolonged periods of outdoor activities.

AccuWeather Meteorologist Ryan Adamson mentioned that some of the rain will be heavy, making flooding a concern west of the Cascades.

By the end of the weekend, around 3 inches of rain is expected to soak Seattle and Portland with as much as 8 inches along the western slopes of the mountains.

Because this storm will bring in warmer air, snow levels should rise to around 8,000 feet in Washington and 10,000 feet in Oregon for a time on Saturday night.

In addition, howling winds lacking from the first storm will kick up with this second one.

Winds gusts of 35-50 mph will batter the coastline and can topple trees and cause power outages in areas west of the Cascades.

Mariners and fishermen will face rough seas and dangerous swells, and beach erosion may be possible as battering waves pound the coast.

The weather will turn more tranquil early next week as the storm track shifts into British Columbia, well north of the border.
