What to plan for in Largo
- 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.
- Coastal flooding (very high): Coastal flooding means keeping batteries, generators and electrical panels above flood level; ask a licensed electrician about elevating equipment.
- 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.
