After Hurricane Harvey hit Texas over the weekend, rescue efforts are underway to bring survivors to safety amid rising floodwaters. Large swaths of the Lone Star State remain underwater, and rain is expected to continue falling for several more days. The state is anticipating a total of 50 inches of rain in what many are calling an unprecedented flood that has killed at least three people thus far.

Police, firemen, rescue workers, military personnel, and volunteers stepped up to help their fellow Americans. Their stories will restore your faith in humanity.

One downtown Houston couple wasn’t affected by the flooding, other than being stuck at home. Instead of just sitting around, they collected wet clothes from people staying at a nearby shelter and dried them.

“We donated extra blankets and pillows and clothes,” Rachel Noise, of Houston, said. “Our neighbors are collecting dog food and dog bowls. Everyone looks homeless down here. They’re either wet and carrying garbage bags of donated items or wet and carrying garbage bags of their belongings. At least we’re doing something instead of watching the horrible news.”

The Texas National Guard will deploy 3,000 more troops to the areas of Texas severely affected by flooding to continue saving those who remain stranded.
