Some 300 American Red Cross blood drives have been canceled because of what was Hurricane Sandy.
The organization says the cancellations mean more than 9,000 blood and platelet donations across 14 states didn't happen.
Blood and blood products were moved to areas threatened by the storm before it hit, but red cross officials say they expect the impact of power outages and the canceled drives to be significant.
On average 44,000 blood donations are needed every day.
