Rain keeps up through Tuesday, flooding possible in western Oregon

The Portland/Vancouver weather forecast from the KGW weather team. Updated several times daily, this includes the outlook around Oregon and in Southwest Washington.

PORTLAND, Oregon — There’s already been over two inches of rain at Astoria and the rain keeps falling.

The western valleys will see two to three inches of rain, while the Cascades and Coast Range see 4 to 8 inches with isolated spots potentially getting swamped with 10 inches of rain.

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

There’s a Flood Watch up for western Oregon and Washington and a Coastal Flood Advisory for tidal overflow along the Oregon and southern Washington coasts.

It will also be warm and windy. Valley highs will push into the upper 50s as south winds of 15 to 30 with gusts of 40 mph bring warm air north.

Wind gusts on the coast will reach between 55 and 65 mph.

There’s also a Coastal Flood Advisory at the coast because of high tides with the new moon, the rain and large swells.

The heavy rain will end Tuesday night.

Wednesday will be mainly dry and partly sunny.

Thursday will begin with morning fog and then become sunny.

A few showers roll in with a weak system Friday, but the weekend looks mainly dry and partly to mostly sunny with morning valley fog.

Have a great night, stay safe and take good care of each other.
