ST. BERNARD, La.(NBC NEWS) - Time-lapse video from security cameras in a St. Bernard Parish fire station show flood waters rising quickly, inundating the southeastern Louisiana building in less than hour.
The National Weather Service used the video to demonstrate Hurricane Ida's danger.
"This is how fast surge can rise," the agency's New Orleans field office said on Twitter. "You are putting your life in danger if you are in a surge prone area. PLEASE STAY AWAY FROM THE COAST!"
