Wednesday and into Thursday, a tropical disturbance will move into the northwestern Gulf of America and currently has a 40% chance of developing into a tropical cyclone before moving northeast and inland across Louisiana and into Mississippi. This disturbance will bring a threat of heavy rainfall and flooding Thursday and into Friday regardless of whether it becomes a tropical storm.
