The threat of snow continues to loom over Portland and other low-lying cities throughout the region.

National Weather Service forecasters still aren’t certain where and when snow will fall — and how much will accumulate. But they said in a new statement Friday that they’re projecting “an increasing risk of snow reaching the valley floors next week.”

Here’s what you need to know about the threat of snow here in Portland:

When’s the snow coming?

The short answer: next week.

The longer answer: Reference to Portlanders’ favorite four-letter word litters the weather service’s forecast.

The weather agency predicts we may get a wintry mix early Monday and will likely see snow that night, when the snow level will drop to 200 feet.

Tuesday brings a chance of flakes throughout the day.

And snow is likely Wednesday through Thursday.

How much is expected to fall?

The weather service said forecasters still aren’t certain how much snow will accumulate. In other words: Don’t put too much stock in potential snowfall totals you see online.

Will my commute be a mess?

Even a few inches of snow can cause widespread commuting problems. Consider taking public transportation if you’re worried about getting around in the snow. And if you do choose to drive, keep tire chains with you and know how to put them on. You’re OK if your car is equipped with traction tires.

Should I stock up on food?

It wouldn’t hurt. The threat of snow isn’t sneaking up on us, so you have plenty of time to run to the store before the (potential) snow rolls in. We’ve even published a winter storm checklist of groceries and emergency supplies.

Authorities also recommend contacting vulnerable neighbors who might need help stocking up before the storm — or shoveling their sidewalks if snow accumulates.

Is there anything else I should do to prepare?

What about snow in the Cascades?

Heavy snow is expected in the mountains.

The weather service predicts multiple feet of snow could fall on Mount Hood over the coming days, for example.

The snowfall will make significant inroads toward replenishing a snowpack that’s well below normal in much of the state.

Drivers headed over the Cascades should expect to encounter wintry conditions.

Should I just start panicking now?

We wouldn’t. Get prepared and do what you can to make your schedule as flexible as possible next week, should snow fall in the city.

Where should I check for updates?

We’d recommend keeping tabs on the National Weather Service’s forecast and social media pages — and OregonLive.com/weather, of course.
