The mistral was blowing so that the windows of the car had to be kept closed.
It is the same whether it rains or shines, or whether the mistral blows or not.
It is a volley of pebbles that the Mistral carries with it as a torrent does.
I have thus had the opportunity of making the acquaintance of the Mistral.
But Mistral's advanced years may excuse it, if excuse is needed.
