  • Watch? Warning? Weather Service aims to simplify the jargon

    Updated: 2013-01-18 09:27:20
    It's the second-most frequent question I get in the weather email box: "What's the difference between a watch and a warning?" It was enough that I finally wrote an entire blog entry breaking down what the various National Weather Service terms mean so I could just send an email link. In the current system, for those who don't want to click the hyperlink above, a "Watch" is usually issued 24-48 hours ahead of an approaching event and means conditions are possible, but not a slam dunk. As the event nears, it will get converted to a Warning (severe conditions are imminent or happening) or an Advisory (less severe conditions are imminent or occurring).
