(Reuters) – Tropical storm Harvey is gaining strength and is expected to be a major hurricane when it approaches the middle Texas coast, the U.S. National Hurricane Center said in its latest update on Thursday.

“Harvey will approach the middle Texas coast on Friday and make landfall Friday night or early Saturday, and then stall near the middle Texas coast through the weekend,” the NHC said.

The system is located 365 miles (590 kilometers) southeast of Corpus Christi, Texas, and packing maximum sustained winds of 65 miles per hour (100 km/h), the Miami-based weather forecaster said.
