In the wake of Monday's cold front, a second cold front will cross the Pacific Northwest Wednesday followed by another atmospheric river. Each of these features will bring additional periods of gusty winds, mountain snow, and heavy to excessive rainfall with renewed flooding. weather.gov

It looks as though the🔥Heat Miser🔥has taken over the latest outlook for Christmas week (Dec 23-29)! There is a high probability of warmer-than-normal temperatures for most of the US. Alaska, the Pacific Northwest, and New England have a better chance of seeing "classic" Christmas weather.
A map titled "8-14 Day Temperature Outlook" issued by NOAA, valid for December 23 - 29, 2025. The map shows a high probability of above-normal temperatures across the vast majority of the contiguous United States. A large area of deep red, indicating a high likelihood (80-100% chance) of above-normal temperatures, is centered over the Southern Plains, covering Texas, Oklahoma, and surrounding states. This heat extends outward in shades of lighter red and orange to the Southeast, Midwest, and Southwest. Small areas in the far Pacific Northwest (Washington state) and the Northeast (New England) are shaded in blue, indicating a probability of below-normal temperatures. An inset map of Alaska shows the entire state covered in blue (below normal), while Hawaii is shaded in orange (above normal).

Additional atmospheric rivers are expected to impact the West later this month. Given the significant river flooding already impacting Washington and Oregon, a continued risk of flooding and landslides is expected across the region through at least late December.
NOAA National Weather Service forecast updated December 11, 2025, details "Atmospheric Rivers affecting the Pacific Northwest and California into late December," specifically December 19-25, 2025. The text warns of heavy rain, high-elevation snow, high winds, and persistent flooding risks. Map (a) shows high and moderate risks for heavy precipitation and snow across the region. Map (b), the "8-14 Day Precipitation Outlook," indicates a high probability of above-normal precipitation for most of the western U.S.

❄️With winter weather ramping up across the country and holiday travel plans right around the corner, always check the forecast and road conditions before hitting the highway!

But in an emergency situation, your vehicle is almost always your best shelter until help arrives. weather.gov/safety
A National Weather Service graphic titled "Stranded in a Snow Storm? Stay in Your Vehicle!" An orange car with its hood open and hazard lights flashing is depicted at the top. The graphic advises: "Don't risk your life: stay inside, stay visible, and stay warm until help arrives." This text is next to a dark green jeep stranded on a snowy road with its headlights on, in a snowy, wooded environment. Three key actions are listed with checkmarks: "Practice carbon monoxide safety (keep your tailpipe clear)" "Conserve vehicle and phone batteries" "Signal for help" A National Weather Service graphic titled "Stranded in a Snow Storm? Practice Carbon Monoxide Safety." An orange car with its hood open and hazard lights flashing is depicted at the top. The graphic provides three tips for carbon monoxide safety: An illustration shows a person shoveling snow away from the tailpipe of a red car. The text reads: "Keep your vehicle and the tailpipe clear of snow while the engine runs." A stopwatch icon is next to the text: "Run the engine only 10 minutes every hour to stay warm." An illustration of a slightly open car window is next to the text: "Open a window slightly for ventilation." A National Weather Service graphic titled "Stranded in a Snow Storm? Conserve Batteries." An orange car with its hood open and hazard lights flashing is depicted at the top. The graphic provides two tips for conserving batteries: An illustration of a smartphone with a low battery icon is next to the text: "Only use your phone when necessary." An illustration of a red car is next to the text: "Turn off car lights and radio when engine is off." The bottom of the graphic shows a dark green jeep on a snowy road at night. An infographic providing safety tips on how to signal for help if you are Stranded in a Snow Storm? The graphic is set against a dark, snowy background with an illustration of a car stuck in the snow at the top. The main title is "Signal For Help" with a large orange checkmark icon. The four instructions are: Hang a bright colored cloth from the antenna or window (accompanied by an icon of an orange scarf). Turn on hazard and interior lights occasionally (accompanied by an icon of a red car with its lights on). Raise the hood when snow stops falling (accompanied by an icon of a red car with its hood up). Place flares or reflective markers near the car if safe (accompanied by an icon of an orange warning triangle).

If you live in the West, you’re likely to see the words “atmospheric river” pop up in the forecast over the next several days.

This is not a new term; in fact it was coined in 1994!

But what is an atmospheric river, and what weather hazards can you expect? Meteorologist Haley Thiem explains.

High winds can be dangerous! If possible, stay inside. When driving, slow down, keep both hands on the wheel, and keep away from high-profile vehicles. Be aware of loose outdoor items and stay clear of trees.

Debris flows often happen in areas where excessive rain causes soil to become so saturated it turns into very runny mud. The mud races downhill, picking up debris such as fallen branches, tree trunks, and rocks as it goes.

Know the risks for your area: weather.gov/safety/flood-hazards

Photo: FEMA
Text on graphic says: "Be Prepared for Debris Flows. Heavy rain can cause debris flows in minutes, potentially burying homes. Areas with low vegetation or recent wildfire burns are especially at risk. Have a plan for your family and be ready to follow instructions from local officials. Get out of the danger area before it begins. There is no time to protect like and property once a debris flow has started." Image next to text shows flooding, building and tree damage from a debris flow.

A prolonged atmospheric river will continue impacting the Pacific Northwest with heavy rainfall. Widespread significant river flooding is underway and is expected to continue through much of the week.

It will be critical to monitor the forecasts now and through the next seven days at weather.gov.

💨❄️High winds, accumulating snow, and icy conditions are expected across a number of states from Montana to Michigan today through Wednesday (Dec. 8 -10) due to two different Alberta Clipper systems moving across the northern U.S.

🚙Get the latest: weather.gov
NOAA infographic titled "Winter's Fury: Alberta Clippers." A map of the United States displays a dashed line with arrows labeled "Common low pressure track" moving southeast from the Canadian border near Montana, across the Great Lakes, to the Mid-Atlantic coast. A yellow shaded band runs along the top of this path with a label stating, "Snow will fall near and north of the low pressure track." A large purple text box explains: "As their name suggests, these fast-moving low pressure systems get their start in Canada and zip across our northern states. They can pack a punch with a narrow band of 'dry' but significant snow. In the winter, these systems commonly bring in below zero temperatures and are often responsible for white-out conditions from Montana to the Dakotas." An additional note adds, "A frigid Canadian air mass sometimes follows on the heels of a clipper system."

A color-coded legend on the left ranges from light green (up to 0.1 inch) to purple (30.0 to 50.0 inches) to show accumulated precipitation. The map depicts a significant precipitation event: Heaviest Rainfall: Deep red and maroon blotches cover the Olympic Peninsula and the coastal mountain ranges of Washington and Oregon, indicating extremely high totals ranging from 8.0 to 15.0+ inches. Major Cities: The I-5 corridor, including Seattle, Tacoma, Portland, and Salem, is covered in orange and red bands, indicating totals between 3.0 and 8.0 inches. Eastern Regions: East of the Cascade mountains (near Bend), the colors shift to greens and yellows, indicating significantly lower amounts between 0.5 and 2.0 inches.
