The South Texas Blood & Tissue Center (STBTC) sent out 350 units of blood on Tuesday in the first large wave of shipments to the hurricane-ravaged Texas Coastal Bend.
Blood drives from Corpus Christi to Houston have been canceled and donation rooms closed following widespread damage and flooding caused by Hurricane Harvey.
As a result, STBTC and blood centers across the country are sending units of red blood cells and platelets to the region.
In South Texas, donors have responded to appeals since the hurricane made landfall on Saturday, making more than 1,600 donations. Monday alone, there were more than 700, almost 400 more than on a typical Monday.
