- Lightning (very high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
- River and heavy-rain flooding (very high): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
- Landslides (relatively high): Decide what must stay on and size backup to that.
