The central area of Catalonia, from Montserrat to the Pre-Pyrenees, covered by fog. Almost the whole district of Bages and the low Berguedà remain under the fog.
The fog develops some winter days with anticyclonic wheather. However, the frequent situation is fog covering just the lowest areas for no longer than midday. The ranges of Sant Llorenç del Munt and Montserrat emerge from the fog, as islands in a white sea looking at each other, while fog flows in between through the valley of river Llobregat.
In 1st picture, the shadow of Montserrat’s summit, Sant Jeroni, is depicted on the layer of clouds. There is one halo of multicolor circles in the left tip of Montserrat’s shadow; this is the spectrum of Brocken, a remarkable optical phenomenon of the shadows in the mist. In 2nd picture, the fog reaches up to the road from can Massana to monastery of Montserrat. In 3rd picture, the range of Sant Llorenç del Munt extending from Montcau to La Mola summits enjoys the sunshine over the fog; behind the range of Montseny.
