What to plan for in Cape Girardeau
- Ice storms (relatively high): Ice storms bring down lines for days. A standby generator with a transfer switch, or a battery sized for the fridge, furnace blower and well pump, matters more than a small power station.
- Winter weather (relatively high): Winter storms and cold snaps combine outages with heating demand. Plan for the furnace blower or heat pump, not just lights, and keep a fuel supply you can reach in snow.
- Earthquakes (relatively moderate): Earthquake risk is mainly about secure mounting and gas shut-off for generators; ask the installer to follow local seismic requirements.
