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.
