NEW YORK — Hurricane Harvey brought record rainfall to Houston and flash floods across the Texas and Louisiana coastal region. The storm also elicited an outpouring of generosity from the retail ­community.

This includes $10 million focused on support of American Red Cross shelters and $2 million in support of the Hurricane Harvey Relief Fund at the Greater Houston Community Foundation. Walmart vowed to continue to deliver water and emergency supplies to the areas in greatest need. Items include cleaning supplies, pet food, batteries, diapers, baby formula, hand sanitizer, first aid supplies, fans, generators, candles, flashlights, propane, rainwear, tarps and gas cans.

“Our Texas family of customers and associates are experiencing devastating impact from this storm,” commented Doug McMillon, president and chief executive officer of Walmart. “We are on the ground to help our friends and neighbors in the Gulf region, and we’ll continue to be in the tough days, weeks and months ahead.”

The company announced a nationwide fundraiser, with proceeds going to help meet basic needs of people in affected areas. In addition, Albertsons and the Albertsons Cos. Foundation vowed to match the first $200,000 donated by ­customers.

“As a company with a long and proud presence in Texas, including the hardest-hit areas, we’re committed to helping our neighbors get through this crisis,” affirmed Bob Miller, chairman and CEO of Albertsons. “We know that the needs are immense, but so is our resolve to making a meaningful impact on the emergency response and humanitarian efforts.”

“As a Houston-area resident, I’m so proud to see Target’s commitment to our teams and communities come to life,” observed John Sheehan, group vice president at Target. “Through these organizations, we’ll provide products, financial assistance and volunteers across the Gulf Coast. Our first priority is supporting our team, getting our stores back up and running and working with these organizations to help the community recover.”
