The American Red Cross held a blood drive at the Palace Theatre Sunday. A steady flow of donors trickled in to help give back.

According to a release by the Red Cross, Snowstorm Nemo caused a shortage of blood in the Northeast, forcing the cancellation of more than 150 Red Cross blood drives and more than 6,500 donations. Donors say the impact of the snowstorm and Hurricane Sandy motivated them to attend.

Blood is used for a variety of life threatening conditions and surgical procedures. The Red Cross said in a statement, "Despite all medical advances, there is still no substitute for blood".

According to the American Red Cross website, someone in the U.S. needs blood every two seconds. The Red Cross provides about 40 % of the nation's blood supply.

For more information, or to make an appointment to donate to the Red Cross, call 1-800-733-2767 (RED CROSS) or visit redcrossblood.org.

All those who donated blood were entered for a chance to win a pair of tickets to Paddy Moloney and The Chieftains at the Palace Theatre on March 12 at 8 p.m.
