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.

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