The last big fuel outage was after Katrina in 2005 when the large parts of the nation experienced fuel shortages and prices spiked to nearly $4/gallon due to the refineries in New Orleans and Baton Rouge being knocked out commission for more than a week. In current dollar value, that is gas of $6/gallon. God forbid a Cat 5 hit Houston directly.
