Route sounding
A graphical route METAR: GFS pressure-level winds, temperatures, and cloud along the great-circle from departure to arrival. Official GRAMET images are not published on a public Chilean HTTP feed, so this desk builds the same briefing from Open-Meteo.
Pink cells mark likely icing (0 to −20 °C with high humidity). Wind barbs are direction/speed in knots at each pressure surface. Cloud opacity follows GFS total cloud cover.
