Flights are arriving and departing again from the New Orleans airport as Tropical Storm Barry heads north.

The Louis Armstrong New Orleans International Airport said in a statement Sunday morning that most airlines are returning to normal operations. The airport is advising passengers to arrive at least two hours early as they could encounter long lines.

Delta Air Lines spokesman Drake Castañeda said Sunday that the Atlanta-based company resumed normal operations in New Orleans Saturday night. Castañeda said Delta flights from Atlanta and New York landed in New Orleans shortly before 7 p.m. Saturday.

President Donald Trump is urging Gulf Coast residents to be careful as Barry continues dropping rain across the region.

In a Sunday morning tweet, Trump said: "A big risk of major flooding in large parts of Louisiana and all across the Gulf Coast. Please be very careful!"

The storm's center is moving over Louisiana on Sunday morning and is expected to move over Arkansas overnight and into Monday.

In its latest update, the National Hurricane Center said the storm is expected to become a tropical depression as it loses energy while moving over land Sunday. Barry's maximum sustained winds were at 45 mph (72 kph) as of 7 a.m. CDT Sunday. But forecasters say the flood threat will continue, partly because of the slow movement of the storm.

Barry is forecast to weaken to a tropical depression soon, but is still expected to drop torrential amounts of rain across a wide region of the South as its center moves over Louisiana on Sunday and Arkansas on Monday.

In its latest update, the National Hurricane Center said the storm is expected to become a tropical depression as it loses energy while moving over land Sunday. Barry's maximum sustained winds remained at 45 mph (72 kph) as of 7 a.m. CDT Sunday.

But forecasters say the flood threat will continue, partly because of the slow movement of the storm. It was moving across Louisiana Sunday morning at about 6 mph (10 kph).

A severe thunderstorm embedded in one of Barry's outer bands began rotating over Mississippi before dawn Sunday, prompting a tornado warning.

There were no immediate reports of any injuries or damage.

The National Weather Service in Jackson says the storm early Sunday morning was capable of producing a tornado near the small town of Ellisville, Mississippi.

Ellisville is about 85 miles (137 kilometers) southeast of Jackson.

Forecasters say the storm that's drenching Louisiana has now prompted a flash flood warning that covers Mississippi's capital city.

The National Weather Service said early Sunday that up to 3 inches (7.6 centimeters) of rain had already fallen in the Jackson area — and more was on the way.

Before dawn Sunday, a narrow band of heavy rain was still streaming north through Jackson. The weather service said that could bring an additional 2 inches (5 centimeters) of rain to the area.

The U.S. National Hurricane Center's 4 a.m. advisory says Barry was centered around 80 miles (125 kilometers) southeast of Shreveport, Louisiana.

The latest advisory from the U.S. National Hurricane Center has discontinued a tropical storm warning for the area including metropolitan New Orleans, although the warning is still in effect from Morgan City to Cameron.

The storm surge warning from the mouth of the Atchafalaya River to Biloxi, Mississippi, was also discontinued as of the 1 a.m. Sunday advisory, but the warning is still in effect for Lake Pontchartrain and the area between Intracoastal City and Biloxi.

The agency says Barry is still carrying "life-threatening flooding rains" as it moves over Louisiana. Forecasters say Barry will move across central and northern Louisiana and then over Arkansas on Sunday night and Monday.

Maximum sustained winds had decreased to near 45 mph (75 kph) and the storm was centered around 45 miles (75 kilometers) southwest of Alexandria.

A weakened Barry inundated the Gulf Coast but appears unlikely to deluge New Orleans as it slowly advances.

Still, Gov. John Bel Edwards on Saturday night urged residents across south Louisiana to stay "vigilant." He warned that Barry could still cause disastrous flooding across a wide stretch of the Gulf Coast overnight.

On Saturday, New Orleans had been braced for heavy rains, but instead had intermittent bands of moderate showers and occasional sunshine.

Forecasters downgraded rainfall estimates for New Orleans through Sunday to between 2 to 4 inches (5 to 10 centimeters). Experts had earlier said the city could get up to 20 inches (50 centimeters) of rain.

As of late Saturday night, the storm had maximum sustained winds of 50 mph (80 kph) and was centered 35 miles (56 kilometers) southwest of Alexandria.
