This would be terrific! A nice ticker to be able to display closing/delays on the homepage, for instance, would be nice as well. Give it the ability to slowly scroll once there are too many schools to fit horizontally on the screen?

I think having a way for businesses/organizations to "claim" a page to pass announcements on would be great. I would suggest the option of being able to approve them before they go live...that way they couldn't be used inappropriately, for example, to advertise a sale instead of using it for it's intended purpose: to pass along closing/hour changes.
Just wanted to chime in and say I agree totally! This is one of the major missing pieces for this app. This was marked as "under review" so wasn't sure if it was accepted for development, or already ready, so wanted to chime in.
