Why will the meeting be postponed?

W:(63)Peter, do you think Amanda will be back from South Carolina in time for our monthly meeting this afternoon?
M: No, I’m afraid she won’t be back by then. She called earlier this morning to say that her connecting flight in Colombia was delayed because of bad weather.(62)She won’t arrive until late this evening.
W:(62)Oh, then we should postpone the meeting until tomorrow or early next week.
M: That’s a good idea, but(64)you and I should still get together to go over the monthly sales report before we leave today.
