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.

As of 7 a.m. Thursday, the system was at the far northern portion of the Gulf, just south of the Mississippi Coast, and is expected to move west, according to the National Hurricane Center. The storm remains very disorganized with a lower chance of formation.

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