NOAA’s 2026–2027 Winter Outlook Is Out: What an El Niño Winter Means for Your Safety
NOAA released its 2026–2027 U.S. Winter Outlook on October 15, 2026, and the forecast—shaped by what forecasters call a very strong El Niño—points to a warmer-than-average north and a wetter-than-average south from December through February. For households, that headline is really a winter weather safety story: a milder, stormier season changes how, when, and where the biggest cold-weather dangers show up, from carbon monoxide after a power outage to flash flooding on hard, dry ground. The National Weather Service’s message was direct: now is the time to plan ahead.
What NOAA’s outlook actually says
The seasonal outlook covers December 2026 through February 2027 and leans on a strong El Niño, which NWS Director Ken Graham said “will likely bring a southward and eastward shift to the jet stream.” That shift tends to steer storms along the southern tier of the country and keep much of the north comparatively mild. The outlook describes the tilt of the odds; it is not a day-by-day forecast, and NOAA is clear that it does not predict snowfall totals because snow generally is not predictable more than about a week in advance.
- Temperature: Warmer-than-average conditions are favored across much of the northern U.S.—the Pacific Northwest, northern Rockies, Midwest, Mississippi Valley, much of the East, and Alaska. The Southeast, including Florida, leans near normal, while the Southwest and Hawaii have equal chances of below-, near-, or above-average temperatures.
- Precipitation: Wetter-than-average conditions are most likely across the South, Southwest, Southeast, and East Coast. Drier-than-average conditions are somewhat more likely in parts of the northern Rockies and Great Lakes, much of Alaska, Hawaii, and the western Pacific islands.
- Drought: Drought is expected to improve or end across the Southwest, Southern Plains, Southeast, and parts of the East Coast, but it may develop or worsen in parts of the northern Rockies, northeastern Oregon, and eastern Washington.
Why it matters for winter weather safety
A “warm north, wet south” winter does not mean a safe winter. The biggest cold-season hazards are tied less to a season’s average and more to individual storms and the power outages that follow them—and those can strike any region, including the parts of the country the outlook favors to run mild. A single ice storm or heavy, wet snowfall can down power lines and send families reaching for portable generators and space heaters, which is where the most preventable winter deaths happen.
Carbon monoxide is the clearest example. The U.S. Consumer Product Safety Commission estimates that portable generators are linked to an average of nearly 100 carbon monoxide deaths a year in the United States. CO is colorless and odorless, it builds up fast in enclosed or partly enclosed spaces, and it does not care whether NOAA labeled your region warm or cold. The wetter signal across the South and East Coast carries its own risk: Graham warned that “too much precipitation on dry soil can fuel destructive flash floods and mudslides,” a hazard for areas coming out of drought where hard ground sheds water instead of absorbing it.
What you should do now
The outlook’s practical value is the lead time it gives you. A few steps taken before the first storm do far more than anything attempted in the dark during an outage. CPSC’s winter-safety guidance lines up closely with what the forecast implies:
- Run generators outside, far from the house. Operate a portable generator only outdoors and at least 20 feet from the home, with the exhaust directed away from doors, windows, and vents. Never run one in a garage, basement, crawlspace, shed, or on a porch—opening a door or window is not enough ventilation.
- Put CO alarms on every level. Install battery-operated carbon monoxide alarms, or alarms with battery backup, on each level of the home and outside separate sleeping areas; interconnected units are best. Test them monthly, and if one sounds, get everyone outside and call 911.
- Give space heaters three feet of clearance. Keep heaters at least three feet from beds, curtains, upholstery, papers, and anything else flammable, set them on a stable level surface, and never leave one running unattended.
- Plug electric heaters straight into the wall. Plug directly into a wall outlet—never a power strip or extension cord—and never run the cord under a rug or carpet.
- Keep outdoor vents clear. After snow or ice, clear buildup away from the outside vents of fuel-burning appliances such as furnaces so exhaust cannot back up into the home.
What to do. Buy and test carbon monoxide alarms now, know where your generator will sit (outside, 20-plus feet from the house) before you need it, and build a simple outage kit—flashlights, batteries, blankets, water, and a charged phone. Doing it before a storm beats doing it by candlelight.
Context and what’s next
Seasonal outlooks shade the odds; they do not promise a specific winter. A region favored to be milder can still see a damaging storm, and the single most dangerous day of the season will not appear on any three-month map. That is why NOAA pairs the outlook with short-range warnings that still drive life-saving decisions. Notably, the agency says it will use “Particularly Dangerous Situation” wording in select Blizzard and Ice Storm Warnings this season to flag high-confidence, historic events—language worth treating as a signal to act immediately, not wait.
NOAA also notes its Probabilistic Precipitation Portal is now operational for snow, ice, and rain-amount forecasts, giving the public more detail as storms approach. The next monthly update to the outlook is scheduled for November 19, 2026, and forecasters will keep refining the picture as the season develops. For most families, though, the to-do list does not change with each revision: check your alarms, plan your heat and backup power, and watch local NWS warnings when a storm is on the way.

Seasonal outlooks describe probabilities, not guarantees, and conditions vary by location. Always follow the guidance of your local National Weather Service office, emergency managers, and the manufacturer’s instructions for any generator, heater, or fuel-burning appliance. If you suspect carbon monoxide poisoning, leave the area immediately and call 911.
