WarningA Warning is a product issued by the NWS (National Weather Service) indication weather hazard is either imminent or has been reported. A warning indicates the need to take action to protect life and property. The type of hazards is reflected in the type of warning (e.g., tornado warnings, blizzard warnings).
AdvisoryAn advisory is a product issued by the NWS (National Weather Service) that highlights special weather conditions that are less serious than a warning. An advisory is for events that may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may cause threatened life and/or property.
Example: On a summer day the high was 90 and the low 70. The average is 80. 80 (average) - 65 (base) = 15 cooling degree-days. It reflects how much power people should be using on the average to cool, in this case their homes/businesses. Take those daily cooling degree days and you can have daily/monthly or annual averages
