NEW ORLEANS—Rescue workers set out in hundreds of boats and helicopters to reach people trapped by floodwaters and utility crews mobilized Monday after a furious Hurricane Ida swamped the Louisiana coast and shattered a large swath of the state’s electrical grid in the sweltering, late-summer heat.
One of the most powerful hurricanes ever to hit the U.S. mainland weakened into a tropical storm overnight as it pushed inland over Mississippi with torrential rain and shrieking winds, its danger far from over.
