Weather questions – the differences between alerts, advisories, warnings, and watches

THE WOODLANDS, TX – The recent – and near-future – storms, combined with the upcoming official hurricane season starting June 1, mean that weather updates and alerts will become a near-daily event. The Woodlands Online Weather team keeps you up to date with the latest weather alerts, advisories, warnings, and watches that are issued by the National Weather Service (NWS) to inform the public about potential or current weather hazards.

But what exactly is the difference between these terms? Here’s an easy breakdown to keep you from getting confused when the phone starts pinging or the winds start howling:

Alerts – Alerts are a broader term for weather information, including advisories and other notifications that may not be as severe as watches or warnings. They’re the news version of a ‘heads up.’

Watches – A watch is used by the NWS when the risk of a hazardous weather event has increased significantly, but its occurrence, location or timing is still uncertain. It is intended to provide enough lead time so those who need to set their plans in motion can do so. A watch means that hazardous weather is possible. People should have a plan of action in case a storm threatens and they should listen for later information and possible warnings especially when planning travel or outdoor activities.

Advisories – An advisory is issued when a hazardous weather event is occurring, imminent or likely. Advisories are for less serious conditions than warnings; if you receive an advisory, it typically means the issue can cause significant inconvenience and, if caution is not exercised, could lead to situations that may threaten life or property.

Warnings – A warning is issued when a hazardous weather or hydrologic event is occurring, imminent or likely. A warning means weather conditions pose a serious threat to life or property. People in the path of the storm need to take immediate, protective action.
