The National Weather Service is changing things this winter, and it’s something people should know about before snow and ice start causing trouble. Winter weather can be more than an inconvenience. A little snow might slow down the morning commute, but a powerful winter storm can make roads nearly impossible to travel, knock out power and put lives at risk.
Knowing when conditions could turn especially dangerous can make a real difference. That’s why the service’s weather experts have decided to create something new that will help keep people safe during the most dangerous of winter storm situations.
A New Level of Urgency for Winter Storms
Beginning with the 2026-2027 winter season, the National Weather Service has announced that it may add the phrase “Particularly Dangerous Situation” (PDS) to certain Blizzard Warnings and Ice Storm Warnings. The designation will be used when forecasters have high confidence that a rare, extreme and potentially historic winter weather event is on the way.
This isn’t something that will appear with every winter storm warning. The NWS is reserving the designation for exceptional situations that pose a significant threat to life and property.
A Blizzard Warning means conditions could make roads extremely dangerous or impossible to travel. An Ice Storm Warning signals the potential for heavy ice buildup that can knock out power, damage property and make travel treacherous.
When a storm reaches that level, people need to know the danger is serious. The new wording is intended to make that urgency clear.
What To Do If a PDS Warning Is Issued
If you see “Particularly Dangerous Situation” included in a Blizzard Warning or Ice Storm Warning, take it seriously. This is the time to avoid unnecessary travel, stay off the roads and prepare for conditions that could become life-threatening.
Even a trip that seems short or familiar can turn dangerous when visibility drops, roads become impassable or ice brings down power lines. If a storm this severe is in the forecast, skip the trip and stay off the roads.
Keep an eye on the latest updates from the National Weather Service and local emergency officials. Winter weather can take a turn fast, so don’t wait until conditions get bad to check the forecast.
The important thing to remember is that, of course, not every Blizzard Warning or Ice Storm Warning will carry the PDS designation. That moniker will be reserved for the most extreme situations, when forecasters have strong confidence that the storm could pose an exceptional threat.
Winter weather is part of life, but some storms are far more dangerous than others. This new warning language is meant to help people recognize when a winter storm is in a category of its own — and when it’s time to take precautions before the worst conditions arrive.
