What to plan for in Middletown
- Winter weather (very 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.
- River and heavy-rain flooding (relatively high): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
- Cold waves (relatively high): Cold waves raise demand and can cause both outages and frozen pipes. Keep at least one room warm with a battery-run heater circuit or a generator.
