When there is a PDS box out, STOP ALL ROAD CONSTRUCTION FLAG-MAN ROAD CLOSURES [...] When a PDS box is issued anything that is going to cause traffic jams should be disabled until the threat is gone!
That really makes no sense... If you look at the area covered by a PDS watch, then connect that to the area affected by tornadoes (if any) within that watch, you are closing a LARGE AREA of construction projects! AR/MS was under 7 hours of PDS TOR on Friday, and most locations didn't even get a cloud (and nobody got a tornado.)
Warnings are another story. But during a watch just doesn't seem to fit the "good idea" header. That's as bad as the schools that shut down for a basic tor-box...
