NWS extended the Storm Surge Watch westward to Intracoastal City Louisiana at 21:00 UTC today. A Hurricane Watch has been issued from the Mouth of the Mississippi River westward to Cameron Louisiana and a Tropical Storm Watch has been issued from north of the Mouth of the Mississippi River to the Mouth of the Pearl River.
The Mississipi River at New Orleans is already at 4.87 m (16 feet) due to historic spring flooding in the central U.S. This is just 30 cm (1 foot) below flood stage.
However, the projected surge of 90 - 1.5 cm (3 to 5 feet) would raise the level to 5.8 - 6.7 m (19 - 22 feet); this is above minor flood stage of 19 feet and major - 6 m (20 feet).
The record level for this area is 6.49 m (21.3 feet) set in 1922.
