PLAQUEMINES PARISH, La.
Plaquemines Parish officials said the boil-water advisory is in effect for all areas that are under a mandatory evacuation ahead of Nate making landfall.
Areas include the Dalcour Water System, Pointe a la Hache Water System, Port Sulphur Water System and south of Oakville only in the Belle Chasse Water System.
Residents will be experiencing lower than normal water pressure in some areas of the parish. Power failures are also expected to cause extremely low water pressure or no water pressure in some areas.
"Because of the low pressure, the water supply is of questionable microbiological quality," parish officials said in an update.
