       This could be a worst-case scenario for this area, but there is still some time to fine-tune the forecast.

       Louisiana and the central and northern Gulf Coast from Upper Texas to the Florida Panhandle should monitor forecast updates over the next several days as surge, wind and flooding impacts could arrive in the timeframe from Sunday to Monday.
