How to help after Harvey

Southeastern Texas has been pummeled with unprecedented flooding this weekend after the arrival of Hurricane Harvey, leaving thousands of residents stranded and in need of help.

Here are some ways to assist victims of the storm:

Disney Day of Giving

The Walt Disney Company and ABC station KTRK in Houston jointly announced a $1 million cash commitment to the American Red Cross in support of recovery efforts for communities affected by Hurricane Harvey.

On Thursday, Aug. 31, Disney will host a Day of Giving across ABC, Freeform, Radio Disney, and all digital and social platforms calling for donations to the American Red Cross to benefit those most affected by the devastating storm.

Help those affected by Hurricane Harvey by visiting redcross.org/abc, calling 1- 855-999-GIVE or texting the word HARVEY to 90999 to make a $10 donation.

American Red Cross

The American Red Cross, a humanitarian organization that provides emergency assistance and disaster relief in times of crisis, is seeking donations to help victims of Harvey.

The organization is accepting donations via phone at 1-800-RED CROSS or text HARVEY to 90999 to make a $10 donation for those in need. Donations can also be made via iTunes.

"The American Red Cross is helping the people affected by Hurricane Harvey in Texas and all across the Gulf coast. Shelters are open, truck loads of supplies are being distributed and volunteers [are] in place," a statement on the organization's website said.

The National Voluntary Organizations Active in Disaster (NVOAD)

FEMA is referring people to NVOAD, a coalition of the major voluntary organizations in the U.S. that have prioritized disaster-related work.

Brock Long, FEMA's administrator, tweeted the name in response to a question about how to help survivors of Hurricane Harvey. The organization's website provides information for people looking to donate or volunteer.

Salvation Army Emergency Disaster Services

Salvation Army Emergency Disaster Services is the relief arm of the charitable organization, which is part of the universal Christian Church. The organization is taking donations to provide "physical, emotional and spiritual care to survivors and relief workers."

Donors can call 1-800-SAL-ARMY to help.

South Texas Blood and Tissue Center

The local blood center placed Hurricane Harvey on the splash page of its website prior to it making landfall, and is still seeking donations to help those affected by the storm.

Catholic Charities USA

Catholic Charities USA, a Catholic social service organization, is seeking donations to help those who have been affected by Harvey.

The group has set up a website devoted to Harvey relief, and explains that "long term recovery" is part of the group's approach to disasters like this one.

"Catholic Charities USA (CCUSA), the official domestic relief agency of the U.S. Catholic Church, needs your support to ensure the delivery of compassionate care and support to individuals affected by disasters. Our agencies provide essential support before, during and after disasters hit," the statement says. "In fact, long-term recovery is an integral part of Catholic Charities' holistic approach and we work tirelessly to ensure individuals can live their lives with the dignity we all deserve. This service is provided to the community regardless of religion, social or economic background."

Save the Children, a children's advocacy group, is opening its own shelters that will include children's supplies and provide children spaces to play while parents deal with personal matters. The organization said it will also help supply other shelters and work with childcare and education providers whose programs were destroyed in the storm.

Save the Children said in a statement that it "will work to help ensure that children's protection needs are prioritized and will seek to supply the shelters with materials to support children's safety, health and hygiene and overall well-being."

They are accepting donations by text or through their website.

Austin Pets Alive!

Austin Pets Alive!, an animal shelter and no-kill pet advocacy group seeking assistance to help with pets, has created a page on its website specific to Hurricane Harvey-related needs.

"Austin Pets Alive! has been helping shelters in the direct line of Hurricane Harvey. We've been working with these shelters to transport as many pets as possible to APA! and as of Saturday morning, we've transported over 235 animals to our shelter," a statement on the website says. "Because of the incredible, humbling support we've received from the community thus far, we have been able to remove some items from our needs list completely."
