Almost 800 rescued in St. John the Baptist Parish after Hurricane Ida
At least three people have died as a result of the storm.
Ida is barreling through Louisiana after making landfall in the state as a powerful Category 4 hurricane on Sunday afternoon.
It was one of the strongest hurricanes on record -- by both wind speed and pressure -- to roar ashore in Louisiana.
Ida, now a tropical storm, is hitting on the 16-year anniversary of Katrina, a Category 3 hurricane that ravaged the Gulf Coast. Hurricane Katrina unleashed a series of events, taking the lives of more than 1,800 people and leaving more than $100 billion worth of damage in its wake.

Power could be out for weeks in hardest-hit areas: Energy company
Power could be out for weeks in the areas hit hardest by Ida, Entergy said Monday.
"Where weather permitted, our crews were out at first light today assessing damage where it was safe to do so," the energy company said in a statement. "This will help us get a better idea of what we’re dealing with. It would be premature to speculate at this time when power will be restored given the extent of the damage."
The ability to reach some areas is hindered by road closures and flooding, the company said.
"In harder to reach areas, we use advanced technology, such as infrared cameras, drones and satellite imagery to assess damage by foot, vehicles, airboats, highwater vehicles and helicopters. Even so, lack of access in areas like waterways and marshes could delay our damage assessment," Entergy said.

Historic landmark tied to Louis Armstrong collapses
The Karnofsky Tailor Shop, a historic national landmark in New Orleans, is one of the multiple buildings that collapsed when Ida walloped the city.
The brick two-story shop, a former tailor business in the Central Business District of the city, dates back to 1913 and is where Louis Armstrong worked before embarking on his legendary jazz career.
The family that owned the shop provided a second home for Armstrong and loaned him money to purchase his first cornet, according to the National Park Service.

Governor expects death toll to go up 'considerably'
Louisiana Gov. John Bel Edwards told MSNBC Monday that search and rescue efforts are ongoing and he expects Ida's death toll to "go up considerably throughout the day."
Helicopters are surveying damage because it will take “many days” to reach Louisiana's southern coastal areas by ground, he said.
Nearly all of southeast Louisiana is without power, the governor said. All eight major lines that feed electricity to the New Orleans area have failed.
