00:00A significant flooding threat because of an atmospheric river event.

00:02It's how Washington State has been starting the week, but to end the week,

00:06the same concerns move south into Oregon and even Northern California.

00:10The next influx of heavy rainfall is Thursday into Friday, and Oregon is the focus.

00:15We're talking 48 inches of rain along the coast and the west-facing slopes of the mountains.

00:19It's where we're most likely to see flooding issues, but once again,

00:22creek streams, rivers, this is going to be a problem as well.

00:26Here's why it's not going to be an exact repeat of what we saw last week in Washington, though.

00:30River forecasts show we get to moderate flood stage, not major flood stage,

00:34and we're not approaching any records when these rivers crest.

00:37So still expect flooding, just not the devastating images that we saw out of Washington last week.

00:42The system is also colder than last week, so we're looking at more snow at pass level,

00:46which helps with the flooding concerns, but doesn't help with road conditions along those passes.

00:51We're talking half a foot to a little over a foot of snowfall by the end of the week.

00:55The overall message here, stay safe.

00:57Have multiple ways to receive alerts about any kind of float watches or warnings that are issued.
