Likening the system to a merry-go-round, Pilié said weather forecasting models Thursday showed the storm doing a full loop around the southeast U.S. before circling back to the Gulf Coast, bringing increased rain chances and the potential for tropical development late next week.

Additional rainfall amounts of up to 1"-2" will be possible for much of Southeast Louisiana. Some locally higher totals will still be possible though. The National Hurricane Center (NHC) has been monitoring an area of low pressure, Invest 93-L. It now has a 0% of development as it moves through Southeast Louisiana.

The storm remains disorganized on Wednesday but still has time to strengthen over the Gulf before making landfall on Thursday.

New Orleans is preparing for heavy rainfall this week as a tropical disturbance moves through the Gulf of Mexico toward the Louisiana coast.

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.

A tropical storm may form this week, bringing risks of flash flooding and strong thunderstorms from Florida to Louisiana.

The heaviest rains are expected to instead take aim at the Acadiana area, but flash flooding will be an issue there and in New Orleans and Baton Rouge metros. Here's more.
