Wind Advisory vs High Wind Warning: NWS Meaning, Speed Thresholds and Safety Steps
Quick answer (source check: October 9, 2026): A Wind Advisory means potentially hazardous non-thunderstorm winds are expected or occurring, usually below the severity that triggers a High Wind Warning. A High Wind Warning means stronger, potentially damaging winds are expected or already happening, so immediate precautions are appropriate. The National Weather Service (NWS) sets different wind thresholds in different forecast areas; a number quoted for one county is not automatically the rule for another.
If you saw either alert in a forecast or a search result today, the next step is to check the exact location, valid start and end times, forecast gusts and safety advice in the local NWS bulletin. A trending search phrase is not proof that the warning covers your home or road.
Wind Advisory vs High Wind Warning: The practical difference
| Alert | Meaning | What to do |
|---|---|---|
| Wind Advisory | Strong winds likely or underway; outdoor items may blow around, high-profile vehicles may be difficult to control. | Secure loose belongings, postpone risky outdoor work, and use caution while driving. |
| High Wind Watch | Potential for the stronger conditions associated with a High Wind Warning; timing or extent may still be uncertain. | Prepare a safe indoor location, adjust travel plans and secure outdoor objects ahead of time. |
| High Wind Warning | Damaging non-thunderstorm winds are expected or occurring. | Seek sturdy shelter, avoid exposed areas and be alert for falling branches, debris and power lines. |
The National Weather Service wind warning guide uses Take Action for both the advisory and the warning, but describes the warning as the more serious wind hazard. A Watch means the conditions are possible and preparation matters. Do not assume an advisory is harmless: fallen trees, unsafe roads and local power outages can occur below a warning threshold.
What wind speeds usually trigger each alert?
Different NWS offices define their criteria for local terrain and impacts. For example, the Cleveland forecast office’s published criteria list a Wind Advisory for sustained non-convective winds of roughly 30–39 mph or gusts in the 46–57 mph range, while its High Wind Warning criteria include sustained winds of 40 mph or greater or gusts of 58 mph or greater.
These are examples, not nationwide cutoffs. Other offices vary the wind speed, duration and thresholds for high elevations. The NWS Spokane region, for example, publishes different valley and mountain criteria on its local definitions page. The alert bulletin itself and the issuing NWS office are authoritative for your address.
Also, these products generally address non-convective wind events. A severe thunderstorm, hurricane, marine gale or tornado may generate another kind of warning with different criteria and more urgent shelter instructions. If you receive more than one alert, read all of them rather than choosing the one that sounds less serious.
How to check whether an alert applies to your ZIP code
Step 1: Open the official local forecast
Visit weather.gov and enter your city, state or ZIP code in the Local forecast field. NOAA’s NWS office directory also explains how to find the forecast office responsible for a given location.
Step 2: Open the full watch or warning text
Look for the product’s issuing office, geographic area, official start and expiration times, maximum anticipated sustained winds or gusts, and any travel or shelter instructions. Forecast graphics are quick summaries; the full bulletin may include elevation-specific details or routes most at risk.
Step 3: Check again before traveling
Alerts can be extended, replaced or canceled as conditions change. A cached screenshot from social media may be outdated even when the general weather situation remains active. Refresh the official source, particularly before a long drive, outdoor event or coastal trip.
What to do before and during a Wind Advisory
Bring lightweight furniture, bins and decorations indoors or anchor them safely. Move cars away from vulnerable trees when practical. Charge essential devices, prepare a flashlight and check on neighbors who may need help carrying outdoor items. Drivers of vans, box trucks, motorhomes and trailers should pay particular attention to gusts on open roads, bridges and overpasses.
During an advisory, slow down if crosswinds are making steering difficult and keep both hands on the wheel. Avoid unnecessary work on ladders or rooftops. If a power line falls, stay well clear and contact the utility or emergency services; never approach or drive over a line.
What changes during a High Wind Warning?
A High Wind Warning should prompt stronger precautions: spend time inside a sturdy building, preferably away from windows or rooms exposed to large trees; postpone outdoor activities that expose you to flying objects; and avoid travel if it is not necessary. If you must drive, follow road closures and local emergency instructions. Wind events can also cause electrical outages and localized damage after the peak gusts have passed.
The NWS wind safety hub provides additional safety guidance for driving, boating, downed trees and objects. Its advice is general; local emergency authorities may issue more specific measures during an active incident.
How is this different from a hurricane or tropical storm warning?
Hurricane and tropical storm products come from the National Hurricane Center and local NWS offices with a separate hazard framework. A powerful tropical system may also bring storm surge, rainfall, flooding and tornado risk, none of which is summarized by a normal Wind Advisory alone.
If you are following a named storm, start with the latest NHC advisories and official local alerts.

Those articles contain date-specific reporting; do not use them in place of live NHC updates.
FAQ
Is a High Wind Warning worse than a Wind Advisory?
Yes. A warning generally indicates higher-impact, potentially damaging non-thunderstorm winds, while an advisory covers less severe but still hazardous winds.
Does a Wind Advisory mean 40 mph winds everywhere?
No. Criteria vary by NWS forecast office and geography. One published office uses 30–39 mph sustained winds or gusts of 46–57 mph, but local official criteria prevail.
Does a High Wind Watch mean strong winds are already happening?
Not necessarily. A watch highlights the possibility of dangerous winds; a warning means they are expected or occurring.
Can I drive during a Wind Advisory?
Driving is not automatically prohibited, but gusts can make travel hazardous, especially for trucks, trailers and high-profile vehicles. Check road restrictions and local forecast details.
Where can I see current warnings for my home?
Enter your location at weather.gov and read the current NWS bulletin for your address.
