We may be getting dry this weekend but rivers still run high

Weather

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!

Flood warnings from NWS

The Flood Warning continues for the following rivers in Oregon and Washington.

Luckiamute River near Suver affecting Polk and Benton Counties.

Nehalem River near Foss affecting Tillamook and Clatsop Counties.

PRECAUTIONARY/PREPAREDNESS ACTIONS… Motorists should not attempt to drive around barricades or drive through flooded areas.

Most flood deaths occur in vehicles.
