It may or may not develop into a tropical depression, but the system will bring rains and the possibility of flooding. Here's the forecast for New Orleans, Baton Rouge and Lafayette.

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