Thousands without power as heavy rain slams western Oregon, SW Washington

A flood watch is in effect through Wednesday morning.

PORTLAND, Ore. β€” Thousands of households across the region are without power Tuesday night as heavy rain hit all of western Oregon and southwest Washington.

Portland General Electric reported more than 5,000 customers were without at 10:20 p.m. Tuesday night. Multnomah County had about 3,600 customers without power.

A flood watch continues for all of western Oregon and southwest Washington. The watch began at 10 p.m. Monday and remains in effect through Wednesday morning.

“Rain will increase tonight and be heavy at times, as the second phase of this extremely wet storm moves inland,” said KGW chief meteorologist Matt Zaffino.

Road closures due to flooding were reported Tuesday in parts of Washington County, including Beaverton. State transportation officials also tweeted a photo of flooding on Highway 101 in Seaside. 

A high wind warning is in through midnight on the north Oregon coast, including Astoria, Cannon Beach, Tillamook, Netarts and Pacific City.

The western valleys are expected to receive 2 to 3 inches of rain through Tuesday night, according to Zaffino. He said the Cascades and Coast Range could get between 4 and 8 inches of rain, with some isolated spots potentially getting as much as 10 inches.

“With the snow level climbing to about 9,000 feet, this is a rain on snow event,” Zaffino said. “That means snowmelt will be added to the rivers and increase the flood threat.”

In addition to the flood watch, Zaffino said there’s a coastal flood advisory for tidal overflow along the Oregon and Southwest Washington coasts.

With several inches of rain in the forecast for the coast range, there is concern of possible landslides like the one that closed Highway 30 last week east of Astoria.

“We’re looking at all of the areas where we see steep hillsides in there, you get to this time of year with this much rain, there’s almost always a lot of problems especially with all of the rain we’ve seen this year,” said Don Hamilton with the Oregon Department of Transportation (ODOT).

Hamilton added that he’s also paying attention to areas recently burned in last summer’s wildfires. He said crews are expected to be very busy making sure roads are clear.

Zaffino said Wednesday will be mainly dry.
