Our main concerns would be ice storms or blizzards in the winter and straight line winds or tornadoes in the summer. We lost our power for 4 days this summer because of straight line winds. One half of the island had power the other half had no power and a lot of dammage due to that storm. We fared OK.
We have a Briggs and Straton generator and our house was wired with a panel that we hook into so that we can select what the power will be used for at any one time. We can run the furnace, which also provides the hot water for our house, or the well pump at one time. In addition to either of those items we can run the refridgerator or the freezer and one light and a wall outlet in the kitchen. We moved the mini TV into the kitchen to get the latest news while I cooked on my gas stove. We alternated running the well and furnace so that we had adequate water and hot water. The neighbors set ups were not as versitile as ours. The most any of them could get was an outlet or a light. No one had running water but us. The all drew off their pools to flush and wash. I took my little lawn tractor and wagon and filled it up with bottles from my basement that I had filled with water and drove it around our street giving drinking water to those who needed it.
We also keep a store of gas on hand in jerry cans. We started this after Katrina,when the gas prices started to jump. I am always concerned that there will come a time when they will ration gas, like they did during the Jimmy Carter era. Up here, on the island, you were only allowed to get 2 gallons. That wont get you far, especially when most people drive 60-80 miles round trip to work each day. Besides the jerry cans we have 2 pick up trucks, 2 cars, a boat with an internal gas tank, snow blower and lawn mower. I look at each of these as a gas storing unit and we try to keep them full as well, just incase.
