(KTEN) — Ardmore, Marietta and Sulphur were ground zero for Saturday's destructive tornadoes. More than 48 hours after the disaster, recovery efforts are continuing to help those effected in the three south central Oklahoma cities.

"For some miracle, with the devastation that we have, we didn't have as many people lost," said Sulphur tornado survivor Analiza Work.

Operation BBQ Relief is providing free meals on Tuesday and Wednesday at the Walmart Supercenter at 2705 Broadway Avenue in Sulphur at noon and 4 p.m. Walmart said it is providing $250,000 in product donations and grants to communities in Oklahoma, Nebraska and Iowa hit hard by weather disasters. 

On Sunday morning and continuing through Monday, volunteers in Marietta worked to provide basic necessities like food, water and clothing to those impacted.

A donation drive started at Marietta Public Schools, but operations have now been moved to the Love County Fairgrounds.

At least 170 volunteers have helped with response and relief projects in the last two days.

"Long term, Marietta did lose our grocery stores,” said volunteer coordinator Kyle Minyard. “That will be an impact on our community for a long time until that gets rebuilt."

Several response organizations including the American Red Cross and Heroes with Hope of South-Central Oklahoma have been assisting the direct hit areas in Ardmore.

BancFirst announced a $250,000 donation to the cities affected, along with a relief fund account that is accepting donations at bank locations and online.

"Hearing it is so much different than seeing it," Analiza Work said. "In the aftermath, and knowing that that was my family in there, and I couldn’t do anything about it but just hunker down and wait ... to see the building here as you see it, I'm thankful she's alive and the rest of them are too. God was watching over everybody."
