Rescuers 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 made a shambles of the electrical grid in New Orleans and beyond in the sweltering, late-summer heat.
One of the most powerful hurricanes ever to hit the US mainland weakened into a tropical storm overnight as it pushed inland over Mississippi with torrential rain and shrieking winds, its danger far from over.
Ida was blamed for at least one death — someone hit by a falling tree outside Baton Rouge — but with many roads impassable and cellphone service knocked out in places, the full extent of its fury was still coming into focus.
