Harvey has reformed as a tropical depression, the National Hurricane Center said.
A hurricane watch and storm surge watch were issued for parts of the Texas coast and a tropical storm watch for other parts of that state as well as the northeast coast of Mexico, an 11 a.m. advisory said. It said watches could be posted Wednesday afternoon for parts of coastal southwestern Louisiana.
At 11 a.m., the storm was about 470 miles southeast of Port Mansfield, Texas. It was moving northeast at 9 mph. Top sustained winds were at 35 mph, just 2 mph below the threshold to again make it Tropical Storm Harvey.
Harvey was expected to produce rains totaling 10 to 15 inches — 20 inches in parts of Texas and Louisiana — as early as Friday morning.

It was delayed by a day or so, but that heavy rain event is coming this afternoon, the National Weather Service says.
The tropical blob that’s been hovering off the South Florida coast was supposed bring rains of 3 inches or more, starting Tuesday morning. That didn’t happen yet, but “the trough is finally here,’ meteorologist Larry Kelly said Wednesday morning from the National Weather Service’s Miami office.
“It was a little delayed but the trough is now draped across the peninsula this morning so we’ll begin to see that wetter weather,” Kelly said. He said rains should start in earnest Wednesday afternoon and into Thursday and Friday, and forecasters are still calling for those 3-plus inches, with local flooding in the places where that tends to happen.
The National Hurricane Center’s 8 a.m. Tropical Weather Outlook said any development of that system will be “slow to occur” and it has a bout a 30 percent chance of becoming a tropical depression, or a Tropical Storm Irma. by this weekend, as it makes a turn to the northeast and back out to the open sea.
As to why the rains didn’t start right, Kelly cited “just timing. It’s a complex science.”
The hurricane center also said the remnants of Tropical Storm Harvey are close to reforming into a tropical depression over the southwestern Gulf of Mexico about 150 miles west of Merida, Mexico, and advisories could start as early as 10 a.m. Wednesday. The outlook said the system could reach the northwestern Gulf Coast late Friday, then slow down, increasing the threat of heavy and long-lasting rains next week cross Louisiana and Texas and the northeast coast of Mexico.
