Wet, warm weather pounds Washington; weather service issues warnings
SEATTLE — March in the Pacific Northwest is staying true to the popular idiom, “in like a lion.”
A wet, sloppy Pineapple Express weather system slammed the region Tuesday night, bringing nearly three inches of rain to the SeaTac Airport in a 24-hour period.
Flood watches were posted for many Washington rivers Wednesday as warmer temperatures brought higher elevation rain and above normal river-runs.
Landslides were also feared after saturated ground gave way to weeks of continues rainfall, with Washington receiving above normal rainfall for all of February and into March.
Heavy rains sparked a landslide that destroyed a home Wendesday morning near the West Valley Highway in Pacific. Near Index, continuous roadway problems worried residents who were already burdened by landslides on private roads. Small slides were also reported near Snoqualmie and in Thurston county, officials said.
“Since the soils are already saturated and unstable, that could cause some landslides across the area,” Burg said.
A flood watch is in effect for most Western Washington counties, as another 2 to 6 inches of rain is likely in the mountains by Thursday night, and another 1 to 3 inches likely for the lowlands. As the snow level hovers around 6,000 feet, some rivers are pushed to their brink.
“These amounts are usually enough to cause flooding on the more flood-prone rivers,” the National Weather Service said in a release.
A flood warning was in affect for the Skokomish River through Thursday night. The weather service told area residents to drive vans or trucks through flooded areas, and warned the river was expected to crest Thursday.
The Jackson Park Gold Course closed holes 12 and 13 after both flooded overnight.
“We will playing the front nine only until further notice,” The golf course posted on its Facebook page.
The Weather service also issued an avalanche warning for the Cascade mountains as the heavy, warm weather put an unstable weight on snowpack. Natural avalanches occurred in the Cascades, and the weather service told backcountry travelers they face a high risk of human triggered slides.
