Worldbuilding Day 2: the Physial Planet

Yesterday I wrote down several climates that can be found in the campaign setting. The exercise for today, which should be called Weather rather than Physical Planet, is to look at the weather that can be found in these climates and develop ten plot devices related to weather.

1. Bad storm at sea, players potentially shipwrecked
2. Snow-in traps players in a remote settlement
3. Sudden flooding along river sweeps away bridge
4. Dry-lightning starts a forest fire
5. Muddy conditions make tracking easier
6. Muddy conditions make roads useless
7. Blizzard closes mountain pass
8. Avalanche closes mountain pass during spring thaw
9. Summer cold snap catches travelers unprepared
10. Long winter nights allow beings that fear the sun to roam the surface
