A warning is used for very active conditions posing a threat to life or property (NOAA NWS). * ADVISORIES highlight special weather conditions that are less serious than a warning. They are for events in active to very active conditions that may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property (NOAA NWS). * WATCHES are issued when the risk of a hazardous weather event has increased significantly, but its occurrence, location, and/or timing is still uncertain. It is intended to provide enough lead time in active conditions so that those who need to set their plans in motion can do so (NOAA NWS). * MONITORING is performed when the risk of a hazardous weather event minimal and its occurrence, location, and/or timing is uncertain. It is intended to update a current epoch status of quiet to active conditions so that those who need to set their plans in motion can do so (SET). * QUIET is announced when the risk of a hazardous weather event is minimal and the occurrence, location, and/or timing is uncertain. It is intended to provide a current epoch status of quiet conditions so that those who need to set their plans in motion can do so (SET). * ALERTS are issued when an event threshold is crossed and contain information that is available at the time of issue. Alerts are provided directly to users who demonstrate an urgent need for such information (NOAA SEC). * SUMMARY MESSAGES are issued after the event ends, and contain additional and corroborating information available at the time of issue (NOAA SWPC).
