EVERETT — Heavy rains predicted this week could bring flooding to Snohomish County, particularly along the Stillaguamish River in the Arlington area.
At least two prolonged periods of rain are expected between Monday afternoon and Wednesday evening, said Josh Smith, a meteorologist with the National Weather Service in Seattle. That could mean up to 3 inches of rain in the lowlands, with more in Darrington, and up to 9 inches in the mountains.
“It’s going to be a little bit soggy,” Smith said.
The Weather Service on Monday issued a hydrology outlook predicting “a plume of moisture” and potential river flooding for much of Western Washington.
The Snohomish and Skykomish rivers aren’t expected to flood, but it depends on the rainfall, Smith said. People should keep an eye on the forecast as the week develops.
The Stillaguamish River in the Island Crossing area is expected to crest above flood stage late Wednesday or early Thursday, according to the Weather Service. Only minor flooding is predicted at this point.
Warmer temperatures are expected until Wednesday as well, but could start to drop again Thursday, Smith said.
Friday temperatures could be back in the 40s, he said.
