Tropical storm warnings are in effect for portions of the Gulf Coast as Tropical Depression 13 approaches the area.
The storm, with maximum sustained winds of 35 miles per hour, was centered about 210 miles southwest of the mouth of the Mississippi River this morning and about 250 miles southeast of Port Arthur, Texas, according to the National Hurricane Center.
The warning is in effect for Pascagoula, Miss., westward to Sabine Pass, Texas, including the city of New Orleans, Lake Pontchartrain and Lake Mourepas.
The depression could become Tropical Storm Lee later today, according to the hurricane center.
The storm is expected to produce rainfall amounts of 10 to 15 inches over southern Louisiana, southern Mississippi and southern Alabama through Sunday.
Meanwhile, Hurricane Katia remains far offshore this morning. The storm has maximum sustained winds of 75 miles per hour.
It is still too early to predict whether Katia will affect the U.S. East Coast.
