What to plan for in Hattiesburg
- 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.
- Strong winds (relatively high): High winds knock out lines on ordinary days. A battery or portable power station handles the common short outages; add a generator for multi-day repairs.
- Lightning (relatively high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
