Hurricane Ida blasted ashore Sunday as one of the most powerful storms ever to hit the US, knocking out power to all of New Orleans, blowing roofs off buildings and reversing the flow of the Mississippi River as it rushed from the Louisiana coast into one of the nation’s most important industrial corridors. The hurricane was blamed for at least one death: a person found dead following a report of a fallen tree on a home in Prairieville, the Ascension Parish Sheriff’s Office said on Facebook. The person, who was not identified, was pronounced dead.
