What typically prompts a weather advisory?

A weather advisory is generally issued for less hazardous conditions that may still pose some risks to public safety. This includes situations like fog or light snow, which may not be extreme but can lead to reduced visibility or slippery roads. These conditions can cause inconvenience and require caution, but they do not typically reach the severity of a warning or watch issued for more hazardous weather events.

While severe thunderstorms and favorable conditions for severe storms are critical weather situations, they invoke higher levels of alerts, such as watches and warnings, due to their potential for substantial impact and danger. Urgent weather updates usually address immediate and critical weather conditions rather than less severe risks. Thus, a weather advisory serves to alert the public about more moderate conditions that necessitate awareness and preventive measures.
