Strong winter storm moving in overnight Monday could knock out power, cause flooding
PORTLAND, Ore. – Forecasters say the strongest storm of the season so far will sweep Western Oregon and Southwest Washington on Monday night, prompting several warnings and watches across the region.
Our own team of meteorologists issued a Storm Tracker Weather Alert as heavy rain and strong gusts will likely bring down trees and power lines, and cause flooding.
The National Weather Service says the storm will move in overnight Monday and into Tuesday. Some areas like the coast and the Cascade Range will see anywhere from 3 to 6 inches of rain, while the Willamette Valley can expect 1.5 to 2.5 inches of rain.
Strong south winds are predicted to move inland from the coast. Gusts could damage trees and knock out power for coastal residents and people living in higher elevations along the Coast Range.
The wind could cause similar damage in the southern and central parts of the Willamette Valley.
A flood watch will also go into effect for most of Western Oregon and Southwest Washington from late Monday through Wednesday afternoon.
Rain will cause water levels in local rivers and creeks to quickly rise, and some minor flooding is possible.
People living in areas that are prone to flooding should be prepared to take action, the NWS said.
With all that rain, the risk of landslides and debris flows increases as well. Rain erosion is a particular concern along the Columbia River Gorge in the burn scar of the Eagle Creek Fire.
You can see which areas are prone to landslides using the Oregon Department of Geology and Mineral Industries' SLIDO tool.
KATU weather reporter Joe English says this is the second in a series of four storms expected to move through the region. The following two are not predicted to be as strong as the one overnight Monday.
