SOS - Stay home!

HAVING GRUMPILY survived still another snowy blitz yesterday, I am left with a question:  Why do TV and radio stations devote so much time and energy to tell us what schools are closed and events cancelled? The list is endless, as expected on a day like yesterday.  Would it not be simpler to mention the one or two that defy the weather and remain open?  But that would eliminate the dramatic  urgency of civic-minded  broadcasting, right?
