How do you know what schools in the Caerphilly area are closed on a certain day?

The best source of information for school closings is usually your local T.V. and radio stations. Radio stations almost always announce the list of closings they receive every few minutes. Television stations usually run an ongoing list of closings across the bottom of the screen or show the list every few minutes. Closings might also be posted on their websites and possibly on the school district's or individual school's websites.
