NEW ORLEANS: Tropical Storm Gordon weakened after making landfall just west of the Alabama-Mississippi border and lashing the U.S. Gulf Coast with high winds and heavy rain early on Wednesday, the U.S. National Hurricane Center (NHC) said.
Gordon is about 20 miles (30 km) northwest of Hattiesburg, Mississippi and was packing winds of 40 miles per hour, it said.
The storm, which is expected to weaken to a tropical depression later Wednesday morning, will likely move across the lower Mississippi Valley through the day, the NHC added.
Flash flood warnings and watches were in effect for inland areas while all coastal watches and warnings associated with Gordon were discontinued at this time, the NHC said.

EVACUATIONS At LaFrance Marina near Ansley, Mississippi, owner Sue Cates said a tidal surge is sure to push water into the marina's low-lying campgrounds, making evacuation "the only choice" people have to protect themselves.
Nevertheless, she said she and her husband will remain in their home, which sits on tall pilings, 24 feet above ground. Built after Hurricane Katrina, the home is made to withstand a 150 mile-an-hour wind, she said.
"We're way up here, and I think we'll be OK," Cates said. "People around here are well-trained for this sort of thing." U.S. oil producer Anadarko Petroleum Corp evacuated workers and shut production at two offshore platforms on Monday, and other companies with production and refining operations along the Gulf Coast said they were securing facilities.
