St. John the Baptist Parish residents are under a boil-water advisory and should cease all water system use, officials said.
"We anticipate water systems catching up overnight.
Please protect and heat pipes that are exposed," officials said.
In an earlier Facebook post, the parish asked residents to cease all water use to avoid complete loss of water pressure.
The parish will issue additional updates on Facebook.
Residents in the affected area are advised to not drink tap water or make ice with it until further notice.
Use caution when bathing infants and children.
Do not consume water or make ice with tap water.
