Yes there has been a snowfall on the Sierra Nevada this morning, right in the middle of May, which will be snowmelt water for tomorrow, thank God!
The Agencia Estatal de Meteorología (Aemet) actually forecast snow and gales in Andalucía for yesterday at levels over 1,700 metres above sea level and for once they hit the mark.
The Grupo de Investigación de Física de la Atmósfera at the Universidad de Granada announced the presence of snow on their Twitter account, saying that there was accumulating snow starting at 2,600 metres, as they have cameras connected to Internet at the Mojón del Trigo observatory.
The snow has fallen in the Borreguiles and Pradollano area, which comes too late for the skiing season, which ended about a month ago.
