Get under the eaves, clean those gutters, watch for flooding in South Sound
Grab your raincoats and don your rubber boots: it’s time for another classic Pacific Northwest damp winter weekend.
A series of storm systems will sweep Western Washington starting Friday and continue into the next week, causing excessive rainfall and potentials for flooding, according to the National Weather Service in Seattle.
The rainfall is predicted to increase in intensity over the weekend, so expect stronger precipitation starting Monday and potentially lasting into the rest of the week, said NWS Seattle meteorologist Anna Lindeman.
This excess rain could cause local flooding over roadways or other areas with poor drainage, so drivers should be cautious of their commute conditions, Lindeman said.
If you plan on fitting in some early holiday travels across the Cascades this weekend, don’t forget your tire chains. Stevens Pass could potentially experience 5 to ten inches of snowfall after the storm system reaches the area on Friday.
Snoqualmie Pass will see very light accumulations of snow, Lindeman said.
If you live on the outer coast, there’s a small chance you’ll experience coastal flooding on Friday and Saturday. As tides on Saturday peak, there’s also a slight chance of inner coastal regions experiencing minor flooding. Those concerns will lessen starting Sunday and into the rest of the week.
The increased rainfall also means that area river levels could rise and begin to flow swifter starting Tuesday. There is a small potential for widespread flooding or at least local flooding on roadways from these rivers, Lindeman said.
As for the wind conditions, expect moderate breezes this weekend that could pick up in intensity starting Monday.
Temperatures should remain pretty much the same as what we’ve been experiencing, with highs in the lower 50s and lows in the upper 40s.
