A damn the weather (or damn-the-weather) is a Prohibition Era cocktail made with Gin, sweet vermouth, orange juice, and a sweetener (either Triple Sec or Curaçao). It is served shaken and chilled, often with a slice of orange or other citrus fruit.
Like many prohibition-era cocktails, the damn the weather was conceived as a way to hide the scent and flavor of poor quality homemade spirits, in this case bathtub gin. The original recipe was included in Harry Craddock's 1930 The Savoy Cocktail Book. A bar/restaurant in Seattle takes its name from the drink.
