You never know how much damage a major storm might do. Assume city water has been contaminated after a hurricane. Do not drink tap water until local officials declare it safe to drink.
The general rule is to be prepared for 3 to 21 days. Stock up on one gallon of water per person per day. Consider filling up a bathtub right before the storm hits.
Invest in a water purifier (removes bacteria / parasites / viruses) and water storage containers for drinking.
