Louisiana and Mississippi are bracing for heavy rains and potentially dangerous flooding as a tropical disturbance moves in. The storm, currently centered just off the Mississippi Gulf Coast, is unlikely to strengthen to a tropical depression.

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.

Its chances for tropical development are less, but rainfall flooding is a threat, regardless, in the lower Mississippi Valley. Here's our latest forecast.

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.

New Orleans is expecting more heavy rain Thursday as the National Hurricane Center monitors a tropical disturbance.

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 once again dropped the likelihood of formation for the tropical system hovering just offshore of Mississippi to 30% in the next two to seven days.

The risk of heavy rain, thunderstorms and gusty winds coming to south Louisiana this week has increased as a low pressure system near Florida heads for the Gulf of Mexico.
