The Red Cross' national blood inventory plummeted 25% in July, and the heat has only intensified since then.
The nonprofit organization said extreme temperatures have exacerbated traditional seasonal obstacles to blood donation, creating an emergency blood shortage.
Local volunteer Marco Bracamontes joined Eyewitness News and said that canceled donor drivers due to the outages caused by Hurricane Beryl made the situation worse along the Gulf Coast.
Blood donations work on a supply and demand model. Right now, blood is going out the door faster than it's coming in.
