HOUSTON — Officials released more water from Houston-area reservoirs overwhelmed by Harvey early Monday in a move aimed at protecting the city’s downtown from devastating floods but that could still endanger thousands of homes, even as the nation’s fourth-largest city anticipated more rain.
Harvey, which made landfall late Friday as a Category 4 hurricane and has lingered dropping heavy rain as a tropical storm, sent devastating floods pouring into Houston on Sunday. The rising water chased thousands of people to rooftops or higher ground and overwhelmed rescuers who could not keep up with the constant calls for help.
Federal Emergency Management Agency Director Brock Long said during a news conference Monday that 50 counties in Texas are affected by the flooding and that a tremendous amount of rainfall is in the cards for southwest Louisiana. The rain and floods have been blamed in at least two deaths.
Residents living near the Addicks and Barker reservoirs — that were designed to prevent flooding in downtown Houston — were warned Sunday that a controlled release from both reservoirs would cause additional street flooding that could spill into homes. Rising water levels and continuing rain was putting pressure on the dams that could fail without the release. Harris and Fort Bend county officials advised residents to pack their cars Sunday night and leave in the morning.
“When the sun comes up, get out,” said Jeff Lindner, a meteorologist for the Harris County Flood Control District. “And you don’t have to go far, you just need to get out of this area.”
The Army Corps of Engineers started the reservoir releases before 2 a.m. Monday — ahead of schedule — because water levels were increasing at a rate of more than 6 inches (15 centimeters) per hour, Corps spokesman Jay Townsend said.
Officials in Fort Bend County, Houston’s southwestern suburbs, late Sunday issued mandatory evacuation orders along the Brazos River levee districts. County officials were preparing for the river to reach major flood stages late Sunday. County Judge Robert Herbert said at a news conference that National Weather Service officials were predicting that the water could rise to 59 feet (18 meters), three feet (90 centimeters) above 2016 records and what Herbert called an “800-year flood level.” Herbert said that amount of water would top the levees and carries a threat of levee failure.
On Sunday, incessant rain covered much of Houston in turbid, gray-green water and turned streets into rivers navigable only by boat. In a rescue effort that recalled the aftermath of Hurricane Katrina, helicopters landed near flooded freeways, airboats buzzed across submerged neighborhoods and high-water vehicles plowed through water-logged intersections. Some people managed with kayaks or canoes or swam.
Houston Mayor Sylvester Turner said authorities had received more than 2,000 calls for help and urged drivers to stay off the roads.
“I don’t need to tell anyone this is a very, very serious and unprecedented storm,” Turner said.
The deteriorating situation was bound to provoke questions about the conflicting advice given by the governor and Houston leaders before the hurricane. Gov. Greg Abbott urged people to flee from Harvey’s path, but the Houston mayor issued no evacuation orders and told everyone to stay home.
The governor refused to point fingers on Sunday.
“Now is not the time to second-guess the decisions that were made,” Abbott, a Republican, said at a news conference in Austin. “What’s important is that everybody work together to ensure that we are going to, first, save lives and, second, help people across the state rebuild.”
The mayor, a Democrat, defended his decision, citing the risk of sending the city’s 2.3 million inhabitants onto the highways at the same time.
“If you think the situation right now is bad, and you give an order to evacuate, you are creating a nightmare,” Turner said.
The Coast Guard deployed five helicopters and asked for additional aircraft from New Orleans.
The White House said President Donald Trump would visit Texas on Tuesday. He met Sunday by teleconference with top administration
officials to discuss federal support for response and recovery efforts.
The rescues unfolded a day after Harvey settled over the Texas coastline. The system weakened Saturday to a tropical storm. By early Monday, Harvey had shifted a little closer to the coast, hovering about 20 miles (30 kilometers) east of Victoria, with sustained winds of about 40 mph (65 kph). The National Hurricane Center said it continued to edge in a southeasterly direction at
3 mph (4.8 kph).
Harvey was the fiercest hurricane to hit the U.S. in 13 years and the strongest to strike Texas since 1961’s Hurricane Carla, the most powerful Texas hurricane on record.
