Minimalist Force of Nature: Air & Heat

A one-page, system-neutral generator for describing air and heat forces affecting an adventure setting. Using up to six rolls of a standard d6, it produces brief details for phenomena such as tornadoes, hurricanes, severe storms, floods, wildfires, blizzards, ice storms, droughts, meteors, and terrain features. Measurements use US units, including yards, feet, hurricane categories, tornado ratings, and miles per hour. The compact rules work with any core system and can also generate environmental descriptions for solo roleplaying.
