Winter weather can change in an instant across Northeast Wisconsin, and the National Weather Service (NWS) is sharpening its warning system for the upcoming 2026‑27 season. In addition to the familiar advisory, watch and warning levels, the agency will now attach a “PDS” tag—short for “particularly dangerous situation”—to the most extreme blizzard and ice storm warnings. The tag signals a rare, potentially historic event that threatens lives and critical infrastructure.
What the different winter alerts mean
Winter weather advisory: This is a “be aware” notice. Conditions may not reach the level of a major storm, but slick roads and delayed commutes are possible.
Winter storm watch: A “get ready” alert. Snow or ice is possible, and residents should start planning before committing to longer trips.
Winter storm warning: A “take action” warning. Dangerous conditions are expected, and travel plans may need to be delayed or canceled.
Severe‑level alerts
Blizzard warning: Strong winds and blowing snow create whiteout conditions, making travel extremely hazardous or impossible.
Snow squall warning: A sudden burst of heavy snow can quickly overwhelm roads and reduce visibility, creating hazardous driving conditions with little warning.
Ice storm warning: Freezing rain is expected to coat surfaces in ice, creating dangerous travel conditions and the potential for widespread power outages.
For the 2026‑27 season, some blizzard and ice storm warnings may now include the PDS tag. When you see a “PDS Blizzard Warning” or “PDS Ice Storm Warning,” expect an event that is both rare and exceptionally dangerous. The NWS will issue these only for storms that could cause life‑threatening conditions and significant damage to roads, power lines, and other critical systems.
Cold‑related alerts
Cold weather advisory: Dangerously cold temperatures and wind chills are expected, with frostbite a concern after prolonged exposure.
Extreme cold warning: Even more severe cold that can cause exposed skin to freeze within minutes. Extra precautions are needed for anyone spending time outdoors.
How to stay safe
Whether you’re heading to a Friday night football game, a Sunday church service, or simply commuting to work, understanding these alerts can help you make safer decisions. When a PDS tag appears, consider postponing travel, stocking up on emergency supplies, and checking on neighbors—especially seniors and families with young children. Keep a charged cell phone, a blanket, water, and non‑perishable food in your vehicle in case you become stranded.
Local officials and emergency managers will coordinate with the NWS to provide timely updates. Follow local news outlets, the NWS website, and official social‑media channels for the latest information. By staying informed and acting early, Wisconsin residents can protect themselves, their families, and their communities when winter’s most dangerous situations arise.
