Hurricane Ida churned on shore in South Louisiana Sunday morning packing 150 mph top winds.

NOAA’s GOES satellite captured images of Hurricane Ida as the sun rose on the Gulf of Mexico and its eye moved over land.

The storm was among the most powerful storms in recent years to strike the United States.

The Category 4 storm hit on the same date Hurricane Katrina ravaged Louisiana and Mississippi 16 years earlier, coming ashore about 45 miles (72 kilometers) west of where Category 3 Katrina first struck land. Ida’s 150-mph (230 kph) winds tied it for the fifth-strongest hurricane to ever hit the mainland U.S.

The rising ocean swamped the barrier island of Grand Isle as landfall came just to the west at Port Fourchon. Ida made a second landfall about two hours later near Galliano. The hurricane was churning through the far southern Louisiana wetlands, with more than 2 million people living in and around New Orleans and Baton Rouge under threat.

“This is going to be much stronger than we usually see and, quite frankly, if you had to draw up the worst possible path for a hurricane in Louisiana, it would be something very, very close to what we’re seeing,” Gov. John Bel Edwards told The Associated Press.

People in Louisiana woke up to a monster storm after Ida’s top winds grew by 45 mph (72 kph) in five hours as the hurricane moved through some of the warmest ocean water in the world in the northern Gulf of Mexico.

Wind tore at awnings and water spilled out of Lake Ponchartrain in New Orleans on Sunday, and boats broke loose from their moorings. Engineers detected a “negative flow” on the Mississippi River as a result of storm surge, U.S. Army Corps of Engineers spokesman Ricky Boyette said.

Edwards said he watched a live video feed from around Port Fourchon as Ida came ashore.

“The storm surge is just tremendous. We can see the roofs have been blown off of the port buildings in many places,” Edwards told the AP.
