The president will also meet victims in Lake Charles, Louisiana after one of the worst natural disasters in U.S. history that is presenting a test of his administration.
The storm, one of the costliest to hit the United States, has displaced more than 1 million people, with 50 feared dead from flooding that paralyzed Houston, swelled river levels to record highs and knocked out the drinking water supply in Beaumont, Texas, a city of 120,000 people.
Hurricane Harvey came ashore last Friday as the strongest storm to hit Texas in more than 50 years. Much of the damage took place in the Houston metropolitan area, which has an economy about the same size as Argentina’s.
Seventy percent of Harris County, which encompasses Houston, at one point was covered with 18 inches (45 cm) or more of water, county officials said.
Mr Trump first visited the Gulf region on Tuesday, but stayed clear of the disaster zone, saying he did not want to hamper rescue efforts. Instead, he met with state and local leaders, and first responders.
He was criticized, however, for not meeting with victims of the worst storm to hit Texas in 50 years, and for largely focusing on the logistics of the government response rather than the suffering of residents.
The White House said Mr Trump will first travel to Houston to meet with flood survivors and volunteers who assisted in relief efforts and then move on to Lake Charles, another area hammered by the storm.
The Trump administration in a letter to Congress asked for a $7.85 billion appropriation for response and initial recovery efforts. White House homeland security adviser Tom Bossert has said aid funding requests would come in stages as more became known about the impact of the storm.
Texas Governor Greg Abbott has said that his state may need more than $125 billion.
The storm, which lingered around the Gulf of Mexico Coast for days, dumped record amounts of rain and left devastation across more than 300 miles (480 km) of the state’s coast.
As water receded, many returned to survey the damage and left hundreds of thousands wondering how they can recover.
In Orange, Texas, about 125 miles (200 kms) east of Houston, Sam Dougharty, 36, returned on Friday where waist-high water remained in his backyard and barn.
His family’s house smelled like raw sewage and was still flooded to the ankles. A calf and a heifer from their herd of 15 were dead. The chickens were sagging on the top two roosts of their coop.
He said: “We never had water here. This is family land. My aunt’s owned it for 40 years and never had water here.”
