The NWS winter weather warning program uses a multi-tiered concept to increase public awareness and promote a proper response to the impending hazardous winter weather event. Generically, the multi-tiered concept is: 

  • Outlook—An outlook is used to indicate that a hazardous winter weather event may develop. It is intended to provide information to those who need considerable lead time to prepare for the event.  NWS Jackson, KY issues a Hazardous Weather Outlook daily detailing any potentially hazardous weather that may occur over the next seven days
  • Watch—A watch is used when the risk of a hazardous winter weather event has increased, but it's occurrence, location, and/or timing is still uncertain. It is intended to provide enough lead time so those who need to set their plans in motion can do so.
  • Warning/Advisory—These products are issued when a hazardous winter weather event is occurring, is imminent, or has a very high probability of occurrence. A warning is used for conditions posing a threat to life or property. An advisory is for less serious conditions that cause significant inconvenience and, if caution is not exercised, could lead to situations that may threaten life and/or property.  NWS Jackson, KY's criteria for deciding on whether to issue a Warning or Advisory can be found below. These can be adjusted if need be to take into account the expected impact of an impending event.
