Hurricane Ida has been downgraded to a tropical depression after it hit the Louisiana coast Sunday as a Category 4 storm on the 16th anniversary of Hurricane Katrina. On Monday, Ida continued to bring torrential rain and flooding to Louisiana and southern Mississippi, where two people died when a flooded highway collapsed. Louisiana’s main utility company Entergy says it could be weeks before it restores electricity to nearly a million people in the storm’s path, including all of New Orleans, as temperatures rise to near 90 degrees.
