PDS is short for Particularly Dangerous Situation. It is a heightened-awareness type of watch issued by the Storm Prediction Center. A PDS tornado watch may say, for example, "Destructive Tornadoes...Hail to 3 inches in diamater...thunderstorm wind gusts to 80mph...and dangerous lightning are possible in these areas."
