The primary risks associated with Tropical Storm Edouard include heavy rainfall, potential flooding, and storm surges along the Gulf Coast, particularly in parts of Texas and Louisiana. Rainfall totals of 3 to 6 inches, with isolated areas receiving up to 9 inches, could lead to localised flooding. The NHC has also warned of the possibility of isolated tornadoes as the storm moves inland. Coastal areas, especially between High Island, Texas, and Cameron, Louisiana, are under a storm surge warning, which could result in significant water inundation.
