Understanding Weather Alerts: Watches, Warnings, and Advisories

When planning travel, it's crucial to understand the different weather alerts issued by the National Weather Service (NWS). These alerts—watches, warnings, and advisories—help you assess potential weather hazards and make informed decisions.

What Is a Weather Watch?

A watch is issued when the risk of a hazardous weather or hydrologic event has increased significantly, but its occurrence, location, or timing is still uncertain. It provides enough lead time for individuals to set their plans in motion. For example, a Severe Thunderstorm Watch indicates that severe thunderstorms are possible in and near the watch area. It does not mean that they will occur, only that they are possible. (weather.gov)

What Is a Weather Warning?

A warning is issued when a hazardous weather or hydrologic event is occurring, imminent, or has a very high probability of occurring. Warnings advise of a threat to life or property. For instance, a Severe Thunderstorm Warning is issued when severe thunderstorms are occurring or imminent in the warning area. Severe thunderstorms are defined as those with winds of 58 mph or higher and/or hail 1 inch in diameter or larger. (weather.gov)

What Is a Weather Advisory?

An advisory is issued when a hazardous weather or hydrologic event is occurring, imminent, or likely. Advisories are for less serious conditions than warnings, causing significant inconvenience, and if caution is not exercised, could lead to situations that may threaten life or property. For example, a Wind Advisory is issued for strong winds that are not expected to reach warning criteria. Generally, this includes sustained wind speeds of 30 to 39 mph lasting for 1 hour or longer.

How Do These Alerts Affect Travel Plans?

Understanding these alerts is vital for travelers:

• Watches: Indicate potential hazards. Travelers should stay informed and be prepared to adjust plans if conditions worsen.

• Warnings: Signify imminent threats. It's advisable to delay or reroute travel to avoid affected areas.

• Advisories: Suggest caution due to less severe conditions. Travelers should exercise care, especially in areas prone to the specific advisory conditions.
