What to plan for in Aurora
- 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.
- Tornadoes (relatively high): Tornado-season storms cut power quickly. A battery that switches on by itself, or a portable generator ready to go, covers the first night; sirens and weather radios need power too.
