To give an idea of how empty can be South Patagonia on the Argentina side (the Chubut and Santa Cruz Province), we are talking of a territory roughly the size of France, with less than 1% if is population, so around 1.5 habitant per square kilometer. So in other words: a desert, with population pushed either on the mountain side (the border with Chili) or the coast side. So what is there to look at ? storms !
Enjoy (or not) and stay tuned !
