Flood Warning Lifted for St. John Parish (Weather Update #18)

A Flood Advisory is in effect as water slowly recedes

Saturday, August 20, 2016 – 3:00 p.m.

St. John the Baptist Parish – The National Weather Service has lifted the Flood Warning for St. John the Baptist Parish and issued a non-life threatening  Flood Advisory to remain in effect until Monday at 3 pm as backwater slowly drains from the area. St. John Parish, especially northwestern portions, remains heavily saturated and ponding of water is occurring on the side of roadways and in ditches and drainage outlets.

Heavy downpours of rainfall are predicted for next week and as a result of already saturated grounds, any additional rainfall will quickly runoff and contribute to street flooding and potentially flash flooding in low-lying areas.  Residents should continue monitoring weather and news stations, water levels and acquiring sandbags for homes and properties. Hurricane Season is in place until November and sand bags will not go to waste if not used during this time.

Emergency Operations Center staff will continue to monitor water levels throughout the weekend and receive updates from the National Weather Service and Governor’s Office of Homeland Security and Emergency Preparedness.
