Hurricane Ida slammed through Louisiana, leaving at least one person dead and knocking out power to the entire city of New Orleans with a population of 400,000.

The powerful Category 4 storm made landfall at 12:55 p.m. on Sunday near Port Fourchon, about 100 miles south of New Orleans, and was downgraded to a Category 3, then to a tropical storm as it made it way across the state on Monday.

Ida is among the strongest hurricanes to hit the United States with maximum sustained winds of 150 mph and its menacing arrival came exactly 16 years after the deadly Hurricane Katrina devastated Louisiana—killing more than 1,800 people and causing an estimated $100 billion worth of damage.

Ida was classified as "extremely dangerous"
