SEATTLE – It will be a wet Christmas week for much of Western Washington.

Storms continue to rage in the region from Monday evening to Christmas Wednesday, and there will be further storms towards the end of the week when traveling after Christmas.

KING 5 has activated First Alert for this weather event that could impact life, property or travel in the Pacific Northwest region. During this event, the First Alert Weather Team will provide you with the latest information to keep you and your family safe.

The National Weather Service (NWS) said there will be a number of systems this week that will likely bring lowland rain, wind and mountain snow. According to KING 5’s First Alert Weather Team, rainfall amounts between 2.5 and 4 inches could occur in the lowlands over the next seven days.

KING 5 meteorologist Leah Pezzetti said a weaker storm front with light rain will move into the region late Monday evening into Tuesday. Above 4,000 to 5,000 feet, mountain snow is expected, with 2 to 8 inches of snow possible.

East and southeast winds could be strong, with the strongest winds hitting the central and northern Cascades and the Strait of Juan de Fuca. A wind advisory is in effect for the lowlands of eastern Puget Sound from 6 p.m. Tuesday through 2 a.m. Wednesday. Sustained winds of 15 to 25 mph with gusts up to 50 mph are expected in this area.

Between 0.25 and 0.5 inches of rain is expected in the lowlands.

High surf is possible along the coast starting Monday, with waves up to 18 to 20 feet, according to the NWS.

Throughout the week, lowland temperatures will not be particularly cold, with highs in the upper 40s to lower 50s.

Weather reports show there are “increasing concerns” for strong winds, heavy rain and heavy mountain snow on Christmas Day, with the possibility of an atmospheric river arriving Wednesday into Thursday.

River flooding outside the Olympic Peninsula could be a concern as water levels rise and the risk of landslides increases.

Snow levels will drop to 3,000 feet, which could make driving and vacation travel over mountain passes difficult. A winter storm warning is in effect for the Cascades from 4 p.m. Wednesday through 10 a.m. Friday. Locations above 3,500 feet elevation could see between 18 and 24 inches of snow.

Wednesday’s system will begin moving out late Thursday morning. However, a second system moves in on Thursday evening, bringing persistent rain to the lowlands and more snow to the mountains.

A third system will move in during the second half of Friday, bringing rain to the lowlands. This system will remain in place until Friday evening

After Friday’s system dissipates Saturday morning, there will be a small break in precipitation as showers ease.
