Human: What is the difference between a weather advisory and a weather watching? Assistant: 
A weather advisory is an official notification given by the National Weather Service that warns of the potential for severe weather in a particular area. This can include thunderstorms, heavy rain or snow, severe winds, flooding and other severe weather events. A weather watch is an alert issued by the National Weather Service when conditions are favorable for the development of severe weather. These conditions would include thunderstorms, strong winds, large hail, tornadoes and other severe weather events that could potentially occur in the area being watched. Ultimately, a weather advisory is more urgent and requires people to take action, while a weather watch is more precautionary and serves to notify people of the potential for severe weather.
