What these closures mean
A closure on this page is a stretch of time the tracker recorded COS1 as closed, mostly because weather reports at the station were of the kind that usually comes with a closure. It is not a confirmed decision by the station: station leadership makes the final call, and what happens to a block during a closure depends on the station and the Flex app, so check the app and your messages.
