The National Hurricane Center says Harvey continues to cause "catastrophic flooding in southeastern Texas."

At least two people have died as Tropical Storm Harvey continues to dump rain on Southeast Texas.

The hurricane center said in its 4 a.m. Sunday update that the tropical storm has maximum sustained winds of 45 mph (8 Beaufort) and remains stationary about 45 miles (72.42 kilometers) northwest of Victoria, Texas.

A storm surge warning and a tropical storm warning also are both in effect for Port O'Connor to Sargent. The hurricane center says a storm surge warning means there is a danger of life-threatening inundation from rising water moving inland from the coastline.

The center says Harvey was likely to weaken to a tropical depression later yesterday. Harvey made landfall Friday night as a Category 4 hurricane.

Meanwhile, the National Weather Service says a Flash Flood Emergency over west and central Harris County, where Houston is located, as well as for eastern Fort Bend and northern Brazoria counties remains in effect until 6:15 a.m. Sunday, calling it a "Particularly Dangerous Situation."

Jersey Village, Texas, officials are recommending that people who live along the White Oak Bayou, about 17 miles northwest of Houston, consider whether they need to evacuate their homes.

Jersey Village City Manager Austin Bleess says the city issued a notice to residents about 1:30 a.m. saying the bayou looked like it would be out of its banks before long. He says city officials worried that streets may soon become impassable and wanted those residents to have time to make arrangements.

"Certainly if people can stay in their homes, they can do that," Bleess said. "It's quite possible that the streets could get impassable so we wanted to get that recommendation out."

Bleess says the city is in the process of opening a storm shelter at the Champion Forest Baptist Church, Jersey Village chapter.

The airport in Austin, about 165 miles (265.53 kilometers) west of Houston, reported sustained winds of 38 mph [7 Beaufort].

The Harris County medical examiner's office confirmed the death of one person late Saturday in Harris County, but the office did not identify the cause of death.

Gary Norman, a spokesman for the Houston emergency operations center, says the woman appeared to have gotten out of her vehicle in high water. She was found by neighbors about 30 yards [27 meters] away from the vehicle. Norman says she was pronounced dead at the scene by a doctor who was in the area.

Earlier Saturday, Aransas County Judge C.H. "Burt" Mills Jr. said the storm left one person dead in the county.

Harvey came ashore Friday night as a Category 4 hurricane, but has since been downgraded to a tropical storm.
