"Heavy rain is already moving through Louisiana and will continue over the next few days," AccuWeather's Alex DaSilva said.

The Florida Panhandle will see heavy rainfall from Invest 93L after it reaches the Gulf on Wednesday. The greatest threat to the area at the moment is flash flooding in low-lying, poor-drainage areas and urban locations. Invest 93L is currently expected to make landfall near Louisiana's southeastern coast Thursday morning.

L continues to move westward across the Gulf Coast and is producing disorganized showers and thunderstorms, according to the National Hurricane Center. The system is expected to continue moving westward across the northern portion of the Gulf,
