What to plan for in Lee’s Summit
- Tornadoes (very 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.
- Hail (very high): Hail is hard on rooftop solar; ask installers about impact-rated panels and your insurer about coverage.
- Heat waves (relatively 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.
