Perhaps the best known legend about the snake is that of the cat headed viper, complete with paws and whiskers, and an uncanny power of fascinating birds. In the district of the Colde Forclaz. to see a snake before noon is a sign of a storm pending in the afternoon. This is probably a sound deduction from the habits of the beast, which is aware that it will have to eat early because the storm will compel it to lie up in the afternoon.
