What is the difference between a watch, warning, and advisory?
The National Weather Service office in Cleveland lists watches, warnings, and advisories under its local criteria and current hazards pages, but the source page does not define how each term differs.
The National Weather Service's Cleveland office maintains a page that brings together weather information for northern Ohio. Its navigation lists several categories, including current hazards, a hazardous weather outlook, a briefing page, local criteria, and sections for winter, space, drought, thunderstorms, hurricanes, and river flooding.
One of the items under current hazards is a link labeled "Local Criteria." That is where local thresholds for hazardous weather are described for the area the Cleveland office covers. The office also publishes a "Graphical Hazardous Weather Outlook" and a "Briefing Page" among its current hazard products.
The page you are reading is the office's front page. It does not explain what separates a watch from a warning from an advisory, and it does not say where such notices are published beyond the links grouped under current hazards. For the actual meanings and the places they appear, you would need to follow those links or check the office's glossary entry.
The glossary is listed in the "About" section of the site, alongside pages about the organization, careers, contact information, and social media. The office's address and phone number are also given on the same page.
Other parts of the site cover past weather, climate and past weather, rivers and lakes, radar, forecasts, safety programs such as SKYWARN and StormReady, and NOAA Weather Radio. The page also carries a "Last Map Update" timestamp.
