Hurricane Ida, the worst storm since Katrina, knocked out an estimated 94% of offshore Gulf oil production, as well as power to one million homes across Louisiana and Mississippi this past weekend. Some 10% of gas stations in the Baton Rouge area were out of fuel — as were 7.5% around New Orleans — leaving thousands lined up for gas to fuel home generators. Gasoline shortages are expected to worsen sharply as Ida passes.
