...FLOODING POSSIBLE THIS WEEKEND IN NORTHWEST OREGON AND SOUTHWEST WASHINGTON
... Another round of heavy rain is expected this weekend, and some rivers could rise above flood stage Saturday night or Sunday. Rivers are already running high from the rain this week, and soils are fully saturated. Rainfall amounts Friday night through Saturday night could be as high as 5 inches in the Coast Range and Cascades and 2 inches for inland valleys.
The details of where and when the heavy rain will occur and which rivers will be most affected will be refined through the week. Watches or warnings for specific areas or rivers will be issued if needed.
Monitor weather and river forecasts closely through the week at weather.gov/portland or mobile.weather.gov. If you live in or near a flood-prone location, this is a good time to review your action plans should flooding develop.
