BUFFALO, N.Y. — When a weather alert is issued, it's important to know the difference between a Watch, Warning, and Advisory.
A warning is issued when a hazardous weather event is occurring, imminent or likely. It means that the conditions pose a threat to life or property soon, if not already happening. People in the path of the weather event need to take protective action.
An advisory is issued when a hazardous weather event is occurring, imminent or likely as well, but is for less serious weather conditions than when a warning is issued. But, caution is still needed to be exercised by those in that area.
A watch is issued when the risk of hazardous weather has increased but its occurrence, location or timing is still uncertain. It is to provide enough lead time so those who need to plan for the possible severe weather conditions in that area can do so well in advance. A watch is often upgraded to an advisory or a warning.
