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

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.

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

Invest 93L is currently churning in the Gulf and is expected to pick up a bit of steam before it makes landfall in Louisiana early Thursday afternoon.

The National Hurricane Center is tracking three tropical waves, including two in the Caribbean. Tropical wave 1: A far eastern Atlantic tropical wave is near 30W from 17N southward, and moving west at 11 mph.

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.

The "reasonable worst-case scenario" is for flooding across lower Acadiana where there's potential for 10-15 inches of rainfall over a 72-hour period, Donald Jones, meteorologist with the National Weather Service in Lake Charles said in a social media update Tuesday afternoon.
