The National Weather Service in New Orleans has issued a Flash Flood Watch for portions of southeast Louisiana and Mississippi, including Upper Lafourche Parish and the Ward 6 area, from Sunday evening through late Wednesday night.
Tropical Storm Sally is expected to make landfall along the southeast Louisiana and Mississippi coasts.
Periods of heavy rainfall are expected to begin as outer bands move in and then more steady heavy rainfall will follow as it makes landfall.
Heavy rains associated with Tropical Storm Sally are expected to spread into the area beginning early Sunday night and will continue over the watch area through at least Wednesday evening.
Total rainfall amounts in the watch area will be 6 to 12 inches with locally higher amounts near 18 inches.
Depending on how much rain actually falls and what river basins see those higher rainfall amounts, river flooding will be possible.
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
