Orleans Parish was without power on Sunday after Entergy New Orleans suffered "catastrophic" transmission damage, the energy company said, as reported by Reuters.
Hurricane Ida, which made landfall as a fierce Category 4 storm, plowed through the Gulf of Mexico into Louisiana on Sunday, lashing the coast with 150 mile-per-hour winds, torrential downpours and pounding surf that plunged much of the shoreline under several feet of water.
Orleans Parish lost power shortly after 7 p.m. on Sunday (0000 GMT on Monday), leaving more than 673,000 customers without power, according to Entergy's outage website.
