A former tropical disturbance failed to form into a tropical depression before reaching the coast, but it could still have serious impacts.

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.

Torrential downpours that can trigger dangerous flooding is the main threat from a tropical rainstorm along the north-central Gulf coast for the balance of this week. Southern Louisiana is in the crosshairs.
