Tornadoes and floods have devastated communities and uprooted families across many states, and the Red Cross is working to provide materials, equipment and blood products to areas hardest hit.
The Red Cross is moving hundreds of blood products to Alabama to make sure hospital patients have the blood they need following the deadly tornadoes there on Wednesday night.
This severe weather has caused the cancellation of 811 blood and platelet donations this week, mostly in the Southeast, South Central and Mid-Atlantic areas.
Maintaining sufficient blood to meet patient needs is a delicate balance between supply and demand. The Red Cross urges eligible donors in unaffected areas to make an appointment to give blood or platelets in the coming days and weeks.
All blood types are needed, but type O-negative donors can make the difference between an adequate blood supply and a shortage.
