Federal Emergency Management Agency director Brock Long said Sunday it could take his agency years to rebuild parts of Texas damaged by Hurricane Harvey.

"FEMA is going to be there for years," Long said during an appearance on CNN's "State of the Union."

"This disaster is going to be a landmark event," he added. "We're setting up and gearing up for the next couple of years."

Also appearing on NBC's Meet the Press, Long said, "There's no such thing as recovery right now. Right now we are deep in to the life safety mission of helping people be rescued through swift water rescues, search and rescue."

The powerful hurricane made landfall in Southeast Texas on Friday as a Category 4 storm, bringing massive flooding and winds as high as 130 miles per hour to the area.

Harvey was downgraded to a tropical storm Saturday afternoon, though the National Hurricane Center has warned residents of the Lone Star State that Houston and its surrounding areas could see more than 40 inches of rain over the next few days.

"This is a storm that the United States has not seen yet," Long said Sunday, noting that Harvey and Hurricane Katrina were nothing alike.

The FEMA adminstrator, who was confirmed by the Senate just two months ago, said President Trump has given his agency all that they need to properly respond to the damage and disperse teams to oversee recovery housing and flood insurance concerns.

"My heart goes out to the people in Texas who are going to go through a very difficult situation," he told CNN. "This is going to be a very dangerous and frustrating event. It's already dangerous, but it's going to be a very a frustrating event."
