As authorities and volunteers continue to search for and assist victims of a devastating flood that swept through a portion of Texas, various groups and celebrities have committed donations to charities in the area.

On Saturday, Shakira, the Colombian singer-songwriter, announced that she would donate a portion of proceeds from her July 5 concert in San Antonio to support families affected by the Texas Hill Country floods.

"Dear San Antonio, Our hearts and prayers are with those affected by the flood in Central Texas," the singer wrote on X. "We are donating a portion of tonight’s show proceeds to Catholic Charities of San Antonio, who are providing disaster relief to the families impacted."

United Services Automobile Association, better known as USAA, has committed $500,000 in philanthropic grants to help with search and recovery efforts and will activate employee volunteers to serve local communities.

"The destruction and loss we are seeing in Texas is heartbreaking, and our thoughts and prayers are with everyone affected, especially the families of those who have lost loved ones and those who are still waiting to hear news," USAA president and CEO Juan Andrade said in a statement. "We have been part of this community for more than 100 years and we will show up with action, compassion and a willingness to help our neighbors and our members recover and rebuild. We are grateful to first responders for their ongoing and tireless efforts."

USAA, which provides banking services exclusively to members of the military, veterans and their families, is based out of San Antonio.

The NFL's Houston Texans have also pledged $500,000 to help with efforts related to the flood.

The Salvation Army in Kerrville, Texas, is taking limited donations and has been designated as the Official Partner for Volunteer Coordination and In-Kind Donations.

The Community Foundation, a nonprofit group in the area, launched the Kerr County Flood Relief Fund. All donations will go to the organizations helping with the emergency.

As of Saturday evening, at least 43 people have died and more than 27 young girls from Camp Mystic remain missing as search and rescue operations continue. 

As officials continue to confirm deaths and search for those missing after the Texas Hill Country floods on Friday, locals have started to share stories of incredible acts of bravery and heroism amid a weekend of anguish.

Julian Ryan and his fiancé Christina Wilson were at their home in Ingram, when water began rushing through the doors.

As the water was quickly rising, Ryan, 27, punched through a window to get Wilson, their children, and his mother out of the flooded house, according to Houston outlet KHOU-11.

Wilson told the outlet the glass cut one of Ryan's arteries and his arm was badly injured. Calls to 911 went unanswered.

"By 6 (a.m.), he looked at me and the kids and my mother-in-law and said, ‘I’m sorry, I’m not going to make it. I love y’all,’" Wilson told KHOU-11.

Ryan is being remembered as a "true hero," who was dedicated to his family, according to a GoFundMe created for the family.

Erin Burgess, who lives in Ingram, told FOX 29 San Antonio she wouldn't have survived if it weren't for her teenage son.

Burgess said that water poured into her home within minutes, forcing her family to seek refuge outside. They hung onto a tree for an hour before water fell low enough for her to hike to a neighbor's house, the outlet reported.

She credited her 19-year-old son, who is more than 6 feet tall, with saving her life.

"That's the only thing that saved me, was hanging on to him," Burgess said.
