Definition: A PDS is a term used to describe a 'Particularly Dangerous Situation' arising from the issue of a severe weather watch or warning. The addition of a PDS watch means there may be some very large hail, severe winds, a derecho, intense lightning, or other severe weather dangers. Typically a PDS watch is rare. Forecasters issuing a PDS Watch must feel there is an imminent threat to life or property. Tornadoes are expected to be either intense, or long-lived.
