The American Red Cross said Hurricane Sandy has forced it to cancel more than 325 blood drives in 13 states and Washington, D.C., resulting in a shortfall of more than 11,000 blood donations.
It says more cancellations and blood donation losses are expected as residents and local officials struggle with the storm's aftermath.
The Red Cross is urging eligible donors to give blood or platelets as soon as they are able.
It says about 44,000 blood donations are needed in the United States each day to meet the needs of accident victims, cancer patients and children with blood disorders.
