Weather or not, we should know.

From time to time, we have heard weather reports which mention words like advisory, warning and watch.  Do you know what it means?

Based upon scientific evidence and probabilities, these three levels of definitions have been developed to assist the public in evaluating the dangers of a weather front.  Here are some practical interpretations.

1)     Advisory

An advisory is issued when special weather conditions are less serious than a warning. They are for events that may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property.  If weather conditions become more serious, weather departments (state, local) will upgrade the situation to a Warning

2)     Warning

A warning is issued when hazardous weather is imminent, or has a very high probability of occurring. A warning is used for conditions posing a threat to life or property. A good example would be when a tornado has been spotted in your area.   A further increase in the hazardous weather will prompt a Watch.

3)     Watch

A watch is used when the risk of a hazardous weather has increased significantly, but its occurrence, location, and/or timing is still uncertain. It is intended to provide enough lead time so that those who need to set their plans in motion can do so.
