PORTLAND -- A powerful storm continued to bring heavy rain to the metro area Monday, downing trees, flooding rivers and knocking out power to thousands.
Heavy rains lasted through the morning commute, but the early morning strong winds subsided. Expect showers throughout the day, said KGW Meteorologist Nick Allard.
Ski areas may get eight to 15 inches of snow by the end of the day from this latest storm.

The driving wind and heavy rains sent trees falling on roads and power lines Monday.
A Flood Watch was in effect through Monday for most of Northwest Oregon and the coastal basins in southwest Washington, according to the National Weather Service.
Some area river basins were already flooding over the weekend and landslides would likely continue, according to KGW Meteorologist Rod Hill. More than 2 inches of rain fell over the weekend.
Landslides and rock slides
Landslides and debris flows are possible during the flood watch. People living in areas prone to flooding should be prepared to take action.
"People, structures and roads located below steep slopes, in canyons and near the mouths of canyons may be at serious risk from rapidly moving landslides," the alert warns.
On Saturday evening, a driver lost control and flipped his car trying to avoid a landslide on Highway 30 in Linnton near the St. Johns Bridge.
Crews were cleaning up a large rock slide that closed eastbound lanes of Interstate 84 through the weekend.
Very windy at the coast
High winds were blowing on the Oregon Coast with peak gusts exceeding 60 mph. Highway 26 was closed about 3 miles east of Highway 101 in Clatsop County due to downed trees and power lines, according to Oregon State Police. Tents set up for next week's Newport Seafood & Wine Festival were blow over Saturday by gusts reported to be close to 80 mph.
Saturday's severe weather knocked out power to thousands in Washington, Marion and Clackamas County.
A 2 a.m. outage at the Portland International Airport prompted backup generators to come on. Flight operations were not disrupted but parts of the terminal and parking garages had dim lighting. (See photo at right.) Power at PDX was restored around 5 a.m
Another rainy weather system coming
There is another weather system expected to arrive on Tuesday that will bring more wind and rain to the area, according to Allard.
"I expect another 1-2 inches of rain from this system with breezy conditions over the valley, and windy weather at the coast. The pattern should calm down a bit through Thursday and Friday and then we should even see some sun for the weekend," he said.
