(WHTM) — With the dog days of summer rapidly approaching, severe weather is not too far behind.
But there is one question that many people ask: What is the difference between a weather watch and a weather warning, and why does it matter?
To put it simply, a weather watch means that the atmosphere is capable of producing whatever weather event the watch is for. For example, if a tornado watch is issued, that means that all of the ingredients to produce a tornado are in place. A watch simply means what it sounds like: to watch the sky and weather radar in case severe weather forms.
A weather warning is much more urgent and serious, very different from a watch. A weather warning means that whatever the warning is for is imminent or already occurring. A tornado warning, for example, means that a tornado is in the process of forming or has already formed.
As far as other types of weather, what makes a thunderstorm “severe” and warrants a warning?
According to the National Weather Service out of State College, for a severe thunderstorm warning to be issued, winds in the storm need to be at or above 58 miles per hour, and/or hail the size of quarters needs to be present within an already formed storm.
Another example of the difference between a watch and a warning has to do with flooding. A flood watch means that the ground is not capable of holding any more water or that rivers are at a high enough level to cause flooding if more rain falls.
A flood warning is when the ground can’t absorb any more water, or when the river is rising higher than what is normal for that river.
To summarize, a watch means to watch for changing weather. A warning means you should take action to protect your life and property.
