PORTLAND, Ore. (KOIN) – Two storms are expected to bring extensive rainfall to Northwest Oregon this weekend, raising the likelihood of possible flooding in several areas.
The National Weather Service issued a flood watch for Northwest Oregon that runs through Sunday afternoon. It includes the Portland metro area, Salem, Eugene the Oregon Coast, the South Washington Coast, the Cascades and the Coast Range.
“A firehose of moisture is aiming right into the region, so expect the threat for heavy rain to continue through next week,” KOIN Meteorologist Riley O’Connor said.
The first storm rolled through Thursday night and the second comes in Saturday morning. There is a risk that the rains will raise levels at rivers that are already running high from rain and snow melt following last weekend’s snowstorm, the NWS said.
“Rain amounts could exceed over 2 inches in the Portland metro area, and over 3 inches for coastal areas through early next week,” O’Connor said.
The rivers most at risk to flood are the Pudding River in Clackamas, the Siuslaw River in Lane County, the Mary’s and Luckiamute rivers in Benton County and the Willamette and Mohawk rivers in Lane County. In Washington, the Gray’s River in Wahkiakum county is at risk. Small streams could also experience flooding.
There have already been area closures due to flooding. Albany closed several parks due to high water. Highway 20 between Corvallis and Newport was partially closed after water from the Yaquina River threatened the foundation of the highway Wednesday.
The farm where popular Oregon-based craft brewer Rogue Ales grows the ingredients that are used in its beers experienced significant flooding this week. A spokesperson for Rogue Farms Hopyard in Independence told KOIN that it was forced to close Thursday and Friday.
Landslides are also possible. The region has already experienced several this week, including an avalanche that killed two skiers in Northeastern Oregon’s Wallowa Mountains, and a massive slide near Hood River that is expected to shut down Interstate-84 east through Monday. On Friday morning, a rockslide closed Northwest Cornell Road in Portland.
