What is Particularly Dangerous Situation?
A Particularly Dangerous Situation (PDS) is a type of enhanced wording first used by the [[Storm Prediction Center]] (SPC), a national guidance center of the United States [[National Weather Service]], for tornado watches and eventually expanded to use for other [[severe weather]] watches and warnings. It is issued at the discretion of the forecaster composing the watch or warning and implies that there is an enhanced risk of very severe and life-threatening weather, usually a major [[tornado]] outbreak or (much less often) a long-lived, extreme [[derecho]] event, but possibly another weather hazard such as an exceptional [[landslide]]s.
