Let's get our priorities straight here

I just noticed something in this pic from the 27 October storm near Fredericksburg.  Take a look at the sign circled in blue on the left edge of the photo.  There is both a "Beware of the Dog" sign and a "No Trespassing" sign...but nothing about "Hey, keep an eye on that approaching funnel!!".  Where are our priorities?
(BTW, I was on public land watching this storm and didn't cross over the line into private property.)
