PORTLAND, Ore. (KOIN) — Overall, a nice, dry weekend is in your future. It will be colder Saturday morning with a few lingering showers. Snow levels may be as low as 1,500′ Saturday morning. Then high pressure takes over for the weekend and we can collectively escape the slap of winter in our face.
Meanwhile, many river communities will be spending this weekend assessing damage and cleaning up. Some roads may still be water logged so be prepared to take a detour. Watch for additional landslides and high, fast flowing rivers this weekend. Most rivers will be lowering from flood stage by Sunday.
We had incredible rain totals from this last week thanks to a vigorous atmospheric river. The month to date total for Portland of 4.03″ inches is only 1 inch shy of the normal rainfall for the month of January. So we’re way ahead of the game for 2022.
And then Astoria had record rainfall Thursday of more than 5″ inches, dumping a crazy old daily record last set in 1914! Astoria’s month to date rain total now is 8.87″. That’s 6.33″ inches above normal month to date. So what is the normal January full month total for Astoria? That’s 10.59″ inches. Almost there!
