On Tuesday, the singer released a statement to the Associated Press pledging her support to those impacted by the flooding, explaining how her Louisiana fans were the first to welcome her with open arms at the onset of her 1989 tour last year.
"We began The 1989 World Tour in Louisiana, and the wonderful fans there made us feel completely at home," Swift said. "The fact that so many people in Louisiana have been forced out of their own homes this week is heartbreaking."
The floods, which started on Friday after a heavy rainfall, have displaced upwards of 30,000 residents and damaged at least 40,000 homes in the days since.
"I encourage those who can to help out and send your love and prayers their way during this devastating time," the "Bad Blood" singer said.
On Sunday, President Barack Obama issued a disaster declaration which will provide federal aid for some of the parishes most affected by the flooding.
Swift has donated to many worthy causes this past year, including allocating $50,000 to a young fan with cancer to pay for her medical expenses. In February, Swift also donated $250,000 to aid her fellow pop star Kesha in an ongoing legal battle for control of her music.
