-40°F (-40°C) represents dangerously cold conditions. Exposed skin can develop frostbite within minutes at this temperature, and hypothermia becomes a serious risk. Roads are treacherous with black ice, vehicles struggle to start as engine oil thickens and battery capacity drops. Schools and businesses often close at these temperatures. Anyone venturing outside needs multiple insulated layers covering all exposed skin, and outdoor exposure should be limited to short periods. Wind chill makes it feel even colder — a 15 mph wind can make -40°F feel 15–20°F colder.
