Rain chances will begin to increase across Acadiana today with scattered showers becoming more likely by the afternoon hours.  Heavier rains are possible across western and northern parts of the state today with a Flash Flood Watch in effect until Noon Thursday for those parishes.  Showers are expected to spread more into the area tonight and for much of tomorrow.  The Flash Flood Watch may get expanded to include more of Acadiana because of the expected rains for Thursday.  Over the next two days, rainfall totals are estimated around 3-5″ inches which could lead to flooding for parts of Acadiana, mainly on Thursday.
