When exactly did the city of New Orleans lose power during Hurricane Katrina?
It’s likely that the Entergy rep was right on. Unless all the major transmission lines drop out of commission simultaneously, widespread power outages are fairly localized and staggered events. Most of the outages are caused by trees falling and downing power lines, so different parts of the city will lose power at different times. As an example, when Hurricane Ike hit Houston, something 90% of Houston lost power, but some lost it at 11pm, some made it to 2 or 3 am, and a few lucky ones never lost it at all. If there’s a specific part of NOLA that you’re interested in, it might be easier to answer.
