It's A PDS! A PDS!

I thought they were making the acronym up, but not according to Wikipedia:

PDS tornado watches are issued when there is a greater risk of multiple strong, violent or extremely violent tornadoes in the watch area (damage consisting of EF4 or EF5), in addition to significant wind and hail damage. While there is no hard criteria for a PDS watch to be issued, they are usually issued when the potential exists for a major tornado outbreak. They represent about 90% of PDS watches issued

Does Pete Delkus know about this?
