New Orleans slammed by Hurricane Ida on 16th anniversary of Katrina

• New Orleans Sewerage and Water Board told WWLTV that it had lost all three feeder lines from energy provider Entergy.

Of note: The National Weather Service said late Sunday it received "multiple reports of significant flooding in LaPlace, in the New Orleans metropolitan area.

• The National Weather Service issued a flash flood emergency for the south shore area of metro New Orleans, imploring those in the area to seek higher ground.
• Emergency medical services were suspended in the city due to dangerous winds, New Orleans EMS tweeted.

The big picture via Axios' Andrew Freedman: Ida, which had killed at least one person in the state as of Sunday night, was stronger at landfall than Hurricane Katrina, but that 2005 storm was much larger. So it drove more water ashore, creating a towering storm surge.

• Ida was one of the major tests for the city's vast, new hurricane protection system, which was not in place 16 years ago when levees failed.

What they're saying: Louisiana Gov. John Bel Edwards noted Sunday the levee system would be tested but added "it was built for this moment."

Flashback: Unlike Ida, Katrina weakened before making landfall in Louisiana on Aug. 29, 2005, as a Category 3 storm with 125 mph winds.

• More than 1,830 people died, and Katrina caused about $176 billion (in today's dollars) worth of damages — the costliest storm in U.S. history, per AP.
