New Orleans, Louisiana – A Flood Watch remains in effect across much of southeast Louisiana and portions of southern Mississippi as heavy rainfall raises the risk of flash flooding from Friday, Jan. 9 through Saturday morning, Jan. 10.
According to the National Weather Service in New Orleans, the Flood Watch covers a large portion of southeast Louisiana, including East Baton Rouge, West Baton Rouge, Iberville, Ascension, Livingston, St. Helena, Washington, Tangipahoa, St. Tammany, Orleans, Jefferson, Plaquemines, St. Bernard, Lafourche, Terrebonne, St. Charles, St. James, and St. John the Baptist parishes. The watch also includes portions of southern Mississippi, including Pearl River, Hancock, Walthall, Pike, and Amite counties.
Cities within the watch area include New Orleans, Baton Rouge, Metairie, Kenner, Gretna, Marrero, Chalmette, Slidell, Covington, Hammond, Denham Springs, Gonzales, Prairieville, Thibodaux, Houma, Mandeville, Bogalusa, Picayune, Bay St. Louis, and McComb.
Forecasters expect widespread rainfall totals of 2 to 4 inches across the region, with localized amounts near or exceeding 6 inches possible by Saturday morning, Jan. 10. Excessive rainfall could lead to rapid runoff and flooding of rivers, creeks, streams, low-lying areas, and urban locations with poor drainage.
The National Weather Service warns that flooding may develop quickly, especially in areas that receive repeated rounds of heavy rain. Residents in flood-prone areas are urged to closely monitor forecasts and be prepared to act if Flash Flood Warnings are issued.
Motorists are reminded not to drive through flooded roadways, as water depth and road conditions can be difficult to judge.
