The San Diego and Imperial counties chapter of the American Red Cross said three volunteers have deployed to Texas, and more deployments are possible in the coming days.
34 Red Cross volunteers from all across Wisconsin are either already in Texas, on their way or taking off Sunday.
"The Red Cross is always at the ready, so we have volunteers ready to deploy to disaster sites 24-7", Rabenstine said.
Hurricane Harvey has weakened to a tropical storm, but continued to drench the Gulf Coast and the worst still might not be over in Texas.
The Red Cross prepared tens of thousands of ready-to-eat meals, "truckloads" of kitchen supplies and more than 40 Red Cross emergency response vehicles are ready to go.
"As in past deployments, we trust they will do great good in bringing relief by those impacted by Hurricane Harvey", he said.
"The images coming out of Texas are heartbreaking and hard to imagine", said Governor Wolf.
The Red Cross has trailers full of shelter supplies including cots and blankets, the Red Cross said. Forecasters are predicting rainfall from Harvey could reach 50 inches in some areas, the highest ever recorded in Texas, according to The Associated Press. Included in their massive 60,000-pound equipment cache are devices that will allow crew members to break into steel or reinforced concrete buildings and structures, as well as listening devices and cameras for finding people needing rescue.
"I really began to appreciate how we can each use our life's experiences and our skills and talents and pull together and make a difference in someone else's life when they're at their lowest point. We are America's disaster relief organization, and we're going to be there for the duration as these families pick the pieces back up and are hopefully able to continue living in that area".
