What is the key difference between a "Warning" and a "Watch" in weather terms?

The distinction lies in the definitions and implications of the terms "Warning" and "Watch." A "Warning" signifies that severe weather is currently occurring or is imminent, meaning conditions are serious and immediate action may be necessary to protect people and property. This indicates that the adverse conditions are likely to occur very soon, often within a few hours.

Conversely, a "Watch" denotes that atmospheric conditions are favorable for severe weather development, but it has not yet been observed. In this case, there's an increased potential for severe weather to form, signaling to the public to remain alert but not necessarily to take immediate protective measures.

Thus, the correct understanding is that a "Watch" indicates conditions are right for an event to happen, while a "Warning" notifies individuals that such conditions are already taking place or will happen very shortly.
