A winter weather advisory means local forecasters expect winter precipitation that will make travel difficult and everyday activities inconvenient, but not severe enough to trigger a winter storm warning. Advisories are issued by National Weather Service offices when forecast amounts or conditions are likely to cause significant disruption, for example light to moderate snow, sleet, freezing rain, or combinations of these that do not meet local warning thresholds.
What a winter weather advisory actually means
A winter weather advisory is a heads up, not an emergency alert. It signals that hazardous winter precipitation is expected, forecast to create travel and commerce problems, and that people should exercise caution. The advisory product is intentionally flexible, because the local impact of the same accumulation can vary widely from Florida to Maine, or from sea level to high elevation.
Typical thresholds and local variation
- Advisories usually cover accumulated snow amounts in the low single digits up to a few inches, or minor accumulations of sleet or freezing rain. Many offices use thresholds in the 1 to 4 inch range for snow, and trace to less than 0.25 inches for freezing rain that is expected to make surfaces slick.
- Each National Weather Service Weather Forecast Office sets its own specific criteria, based on local climatology, road network sensitivity, and public impact. That means a single inch of snow may trigger an advisory in one region, while it would not in another.
Advisory versus watch and warning
Product | What it means | Typical public action |
|---|---|---|
Winter Weather Advisory | Hazardous winter weather expected, causes inconvenience and travel problems, but not life threatening at widespread scale | Slow down, avoid non essential travel, prepare supplies |
Winter Storm Watch | Significant winter weather possible within 12 to 48 hours, conditions favorable for heavy snow or ice | Monitor forecasts, check travel plans, prepare emergency kit |
Winter Storm Warning | Dangerous winter weather occurring or imminent, likely to be life threatening or cause major disruption | Stay home if possible, follow emergency instructions, expect outages |
Why forecasters issue advisories
Advisories are a decision tool for meteorologists and emergency managers, they help communicate risk at a level below warnings but above routine forecasts. The aim is to give the public time to adjust plans, let road crews stage equipment, and allow businesses and schools to consider modified operations. Because impact is the measure, local offices will issue advisories based on a combination of precipitation type, expected accumulation, timing, and surface temperatures.
"An advisory is intended to get people to take simple precautions, because even small amounts of snow and ice can quickly make roads treacherous," a forecaster told officials, during a recent winter preparedness briefing.
How to prepare, practical steps
Public health and emergency management agencies recommend a layered approach to readiness.
At home
- Keep a three day supply of food and prescription medication, and have fresh batteries and flashlights at hand.
- Insulate pipes and know how to shut off water in case of freezing or damage.
- Have a backup heating plan if you depend on electricity, and never use generators indoors.
In your vehicle
- Create or restock a winter emergency kit, including warm clothing, blanket, water, non perishable food, a first aid kit, shovel, windshield scraper, and portable phone charger.
- Keep the gas tank at least half full to reduce condensation and avoid running out if you get stuck.
- Fit winter tires or chains when appropriate, and check tire pressure before travel.
During the advisory
- Avoid travel if possible, and if you must drive, reduce speed and increase following distance.
- Tell someone your route and expected arrival time, and carry a charged phone and charger.
- If you become stranded, stay with your vehicle unless safety dictates otherwise, run the engine for short intervals to stay warm, and ensure the exhaust pipe is clear of snow.
What agencies and local authorities do
State and local transportation agencies adjust plow and salt operations as advisories are issued, and public transit systems may alter schedules. Schools and employers use advisories, along with local forecasts, to decide on delayed openings or closures. Emergency managers often monitor advisory products to determine whether to escalate to a watch or warning.
Communication and public trust
National Weather Service offices publish advisories on their websites and push them through NOAA weather radio, social media, and emergency alert systems. Wireless Emergency Alerts and local media also relay advisory information. Trust in forecasts depends on clear, consistent messaging, and on forecasters having sufficient staffing and tools to run models and issue timely products.
Multiple outlets have reported operational stress at some forecast offices, which can complicate staffing during busy winter periods and raise concerns about sustaining round the clock services. That reporting has prompted calls for investments in personnel and infrastructure, so that advisories, watches, and warnings reach communities reliably.

This is a stylized example, advisory wording and format will vary by office, and by the event.
Multiple viewpoints and balance
Meteorologists emphasize that advisories serve to reduce unnecessary travel and minor crashes, they are not meant to cause alarm but to prompt precaution. Emergency managers focus on the ripple effects, such as school closures and staffing for critical services. Public health officials stress that cold exposure and carbon monoxide poisoning are real risks when people use alternate heating or become stranded. Finally, journalists and watchdogs have pointed to resource constraints in some forecast offices, arguing those constraints make reliable communication harder during peak winter seasons.
Where to get the most reliable local information
- Your local National Weather Service office page, which lists current products and local criteria.
- NOAA Weather Radio for continuous updates.
- State department of transportation alerts for road conditions, and trusted local news outlets for community impacts.
Bottom line
A winter weather advisory means exercise caution, change plans if you can, and prepare for travel delays and slick surfaces. It is a practical, impact based signal from forecasters, tailored regionally to account for local roads and climatology. Take the advisory seriously, update your plans, and use official local sources to follow the event as it develops.
