A wave of storms is expected to hit the Pacific Northwest this week bringing up to nearly a foot of rain along the coast and in the Cascades. This could lead to mudslides and flooding in the lower elevations. The snow level will be around 7,000 to 8,000 feet until Wednesday night, at which point colder air is set to arrive with snow levels dropping to nearly 2,500 feet. That’s when big snow can be expected.
Monday was the wettest calendar day in recorded history in Portland, Oregon and the rain is expected to stick around for the rest of the week. This has already led to flooding, landslides and road closures. The pouring rain triggered landslides, forced people to abandon their cars and caused widespread flooding on Monday. Johnson Creek flooded in Portland and Milwaukie, Oregon sending floodwaters over bridges and into roads.
On Monday morning, Portland’s combined sewer system overflowed into the Willamette River and the Columbia Slough.The Bureau of Environmental Services urged people to avoid coming into contact with waterways and floodwaters.
