According to the National Hurricane Center's 11 a.m. ET update on Tropical Storm Barry, the storm's winds are now reaching 65 mph.
A tropical storm becomes a hurricane when wind speeds reach 74 mph.
A hurricane warning remains in affect for portions of the Louisiana coastline.
The storm is continuing to move north at a pace of 5 mph, and the slow speed could further strengthen the storm before it makes landfall.
"The slow movement of Barry will result in a long duration of heavy rainfall and flood threat along the central Gulf Coast," the National Hurricane Center said.
