the mountain's slow exhale, feeding rivers months after the storm forgot it ever fell

means The water produced when accumulated snow and ice thaw, typically in spring, which feeds streams, rivers, and reservoirs.

from A plain English compound, exactly what it says: "snow" (Old English snāw, a word shared across the Germanic and beyond — Latin nix, Greek nipha — all tracing back to an ancient Indo-European root for the white stuff) joined to "melt" (Old English meltan, to dissolve or become liquid). The word itself is fairly modern, the kind of clear, functional term hydrologists and mountain folk reach for when describing where the river's water actually comes from.
