Hurricane Harvey: What’s Next And How to Help

What’s happening on the ground

Local officials blame at least 31 deaths and many more injuries on the storm, which has inundated parts of the Houston area with more than three feet of rain. In some places, totals surpassed 50 inches, setting a record for the continental United States. And, in Harris County, which includes Houston, up to 30 percent of the land had flooded, according to Jeffrey Lindner, a meteorologist for the Harris County Flood Control District.

While the storm began to release Houston from its grip on Wednesday, it continued to wreak havoc east of the city: “Our whole city is underwater,” Derrick Freeman, the mayor of Port Arthur, Texas, said on Facebook early Wednesday.

Harvey is now hitting southwestern Louisiana, too, where storm surge warnings and watches are in effect. Here are some maps of its path and destruction.

As the storm strengthened over the weekend, experts at the National Hurricane Center raced to warn the public of what was to come and grappled with how to convey its scope. More than a trillion gallons of rain fell in Harris County in four days — enough to “run Niagara Falls for 15 days,” Mr. Lindner said.

Officials sought to reassure undocumented immigrants that immigration enforcement would not be conducted at shelters and Houston’s hospitals struggled to treat victims. The brutal storm also put the brakes on the area’s recent economic upswing and revealed vulnerabilities for the oil and gas industries.

Here are some of the most powerful photos of the devastation and a before-and-after look at the storm’s impact. If you can do so safely, please share your own photos and videos here, or leave us a voice mail message. And listen to Tuesday’s episode of “The Daily” podcast to hear from some people who fled the storm.

Who is responding and how?

Overwhelmed emergency responders were aided by a massive volunteer rescue effort that operated with little official direction. In some cases, state troopers even referred some requests for help to civilians.

President Trump visited Corpus Christi on Tuesday to survey some of the damage and demonstrate a commitment to the recovery effort in the state.

On Tuesday evening, the mayor of Houston also announced that the Toyota Center, an 18,000-seat indoor arena, would open to relieve the pressure on the convention center. Tens of thousands of people were in shelters. In San Antonio and in Houston, some of them spoke to Times reporters about their fears for what awaited them back home.
