Thousands of people and animals have been displaced from catastrophic flooding in Houston and other communities in the region. Hundreds of homes are underwater and many have been completely destroyed. The disaster isn't over yet. It's really just beginning as people in some communities return to what's left of their homes.

Residents in Texas and western Louisiana are going to need help for many months to come.

Here are tips on how you can help and which organizations are on the ground in Texas and Louisiana.

1.  Verify the trustworthiness of soliciting relief organizations by visiting Give.org to access free reports that specify if the charity meets the 20 Better Business Bureau Standards of Charity Accountability.

2.  See if the charity has an on-the-ground presence in the affected areas.

3.  Find out if the charity is providing direct aid or raising money for other groups.

4.  Be cautious about gifts of clothing, food or other in-kind donations.

5.  Understand crowdfunding. Keep in mind that some crowdfunding sites do very little vetting of individuals who decide to post for assistance after a disaster, and it is often difficult for donors to verify the trustworthiness of crowdfunding requests for support.

6.  Phases of disaster relief. Remember that every disaster has several phases – rescue, emergency relief and recovery. Each part relies on public support and continuing funding for success.

7.  Recovery time line. For many communities, recovery will be a long-term activity that can take many months or years to accomplish.

8.  Disaster planning.  Areas that work toward recovery will probably also need to develop plans to better respond to a similar storm in the future.
