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.

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

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.

There’s growing concern for another significant rain and flooding event this week, this time along the Gulf Coast, from what could become the Atlantic basin’s next tropical system.

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

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

A system was detected off the Atlantic Coast of Florida and is expected to move into the northern Gulf Coast and develop into a tropical depression.

Hurricane center forecasters said the system, designated as Invest 93L, is forecast to continue moving westward and could emerge or redevelop.
