Why Prepare by the Numbers
Atlantic hurricane season runs June 1 to November 30. After a major hit, utility restoration in the Caribbean commonly takes days to weeks. Guessing fuel and water needs leads to either dangerous shortfalls or wasted money on storage you cannot keep fresh.
Fuel Strategy
Run the generator in blocks — a few hours morning and evening keeps the fridge cold and phones charged while using a third of the fuel of continuous running. Diesel stores 6-12 months with stabilizer; gasoline degrades in 3-6 months. Rotate stock through your vehicle. Propane stores indefinitely and is the best choice for infrequent use.
Water Rules of Thumb
Plan a minimum of 1 gallon per person per day for drinking alone, and about 5 gallons total including cooking and hygiene. A family of four preparing for 7 days needs roughly 140 gallons — more than most people expect, which is why fixed tank storage (see the Water Tank Calculator) beats scrambling for bottles.
Battery + Generator Pairing
A battery/inverter system covering overnight essential loads means the generator only runs to recharge during the day — quieter nights, less fuel, and no CO risk while you sleep. Size it with the Battery Bank Calculator using your essential load.
