NATCHEZ — A potential tropical storm system that threatens to drench the Mississippi Gulf Coast and parts of southern Louisiana with heavy rainfall will likely have minimal impact on Adams County and Concordia Parish.

Forecasters say the Alabama and Mississippi coasts could be inundated with as much as 15 inches of rain from a the storm system in the Gulf of Mexico.

National Weather Service meteorologist Anna Wolverton said the storm, currently named Potential Tropical Cyclone Three, will likely impact eastern Mississippi more that the western portion of the state.

“The main impact (in Adams County and Concordia Parish) is going to be rainfall,” Wolverton said. “Right now, we are expecting storm totals to be 1-2 inches … through Thursday night into Friday morning.”

While Wolverton also said the area could experience wind gusts up to 20-25 mph, she said the storm mostly “won’t be impactful” to Adams County and Concordia Parish.

Wolverton, however, did not rule out the possibility of flash flooding or rain totals of more than 1-2 inches in isolated areas.

The heaviest rains are expected in an area that includes the port city of Mobile, Ala., and the cities of Pascagoula and Biloxi. The forecast shows an even wider area from southeastern Louisiana into the western Florida Panhandle could receive as much as 10 inches of rain over three days.

The National Weather Service issued an expanded flash flood watch for the area Tuesday, and forecasters say the flooding threat will continue through Thursday night.

The National Weather Service issued a tropical storm warning that covers an area from High Island, Texas, to the mouth of the Pearl River between Louisiana and Mississippi. The tropical storm warning means tropical storm conditions are expected somewhere in the warning area in the next 24 to 36 hours.

A tropical storm watch is also in effect on the upper Texas coast from west of High Island to San Luis Pass.

At 10 a.m., the center said disturbance No. 3 was centered about 265 miles south of Morgan City, La. — or about 355 miles southeast of Galveston, Texas. It’s maximum sustained winds are at 40 mph  and the storm is moving toward the northwest at 10 mph.

The National Hurricane Center says the storm is expected to move inshore early Thursday near the Louisiana-Texas line before weakening and moving northeastward in a sweeping arc.

If Tropical Cyclone Three does achieve sustained winds of at least 39 mph, it will officially be named Tropical Storm Cindy.
