A bulletin issued by NWS offices which alerts the public to a non-severe, yet significant weather event which is expected to remain below the warning criteria, but may still cause significant inconvenience. These events can produce life and property damage if caution is not exercised. See Air Stagnation or Pollution Advisory, Blowing Snow Advisory, Dense Fog Advisory, Freezing Rain or Drizzle Advisory, Heat Advisory, Lake Snow Advisory, Snow Advisory, Urban and Small Stream Flood Advisory, Wind Advisory, Wind Chill Advisory, Winter Weather Advisory.
Statements issued by a weather service that discuss weather situations of inconvenience that do not carry the danger of warning criteria, but, if not observed, could lead to hazardous situations. Some examples include snow advisories stating possible slick streets, or fog advisories for patchy fog condition causing temporary restrictions to visibility. See also special weather statements.
