Fog

Source GM Core pg. 95 2.0
Fog imposes a circumstance penalty to visual Perception checks, depending on the thickness; it causes creatures viewed through significant amounts of fog to be concealed; and it cuts off all visibility at half a mile or less—possibly much less. Conditions limiting visibility to about a mile are called mist, and those that do so to about 3 miles are called haze.
