What to plan for in Florissant
- Heat waves (very high): Heat waves strain the grid just when air conditioning matters most. Decide what must stay cool, such as one room, medicine and the fridge, and size backup to that rather than the whole house.
- Hail (very high): Hail is hard on rooftop solar; ask installers about impact-rated panels and your insurer about coverage.
- 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.
