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.

Flooding was possible across some parts of Southeast Texas, mainly east of Interstate 45, and in East Texas along the Texas-Louisiana border.

While most of Texas will stay dry over the next several days, far East Texas will have a chance of significant tropical rainfall.

Prepare for rain, New Orleans. A low pressure system headed for the Gulf of Mexico is expected to bring heavy rain, thunderstorms and gusty winds to south Louisiana later this week, though just how much of each is still in question.

If the storm were to speed up, it would push the tropical rain across the central Gulf Coast. A storm which stalls over the Gulf or Louisiana could result in more widespread heavy rain and flooding.

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