Do threat clocks advancements happen “on-screen”?

In some of the examples, threat countdown clocks tick down early with somewhat mundane stuff at the 3:00, such as two NPC’s meeting each other, not necessarily requiring the PC’s to be present. I get that warning players of impending danger is a MC move I can use, but sometimes it doesn’t make fictional sense for the PC’s to be present at that scene. So can I cloak a move to have it happen anyways, but not inform the players that it happened or should I look for other opportunities?
