The National Hurricane Centre says Hurricane Harvey continues to cause "catastrophic flooding" in southeastern Texas.
The hurricane centre says the tropical storm has maximum sustained winds of 72.42 kph and remains stationary 72.42 kilometres 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 centre says a storm surge warning means there is a danger of life-threatening inundation from rising water moving inland from the coastline.
The centre says Harvey is likely to weaken to a tropical depression later on Sunday. Harvey made landfall on 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 calling it a "Particularly Dangerous Situation."
The beach town of Rockport, home to about 9,000 residents, looked like a war zone on Saturday afternoon. Winds of up to 209km/h had sheared dozens of houses in half, peeled the roofs of hundreds more and blown out thousands of windows.
Splintered lumber littered the empty streets, some of which were flooded by up to two feet of seawater. Downed power lines sagged menacingly. Windowless shops in a strip mall near the seafront stood fully exposed to the torrential rain.
