HAMPTON ROADS, Va. (WAVY) -- The American Red Cross is urging eligible donors in the area to give blood or platelets now.

The winter weather has made for a severe blood shortage throughout the Mid-Atlantic Blood Services Region.

Snowy and icy roads forced 27 blood drives to cancel in the region, causing about 750 donations to go uncollected. Last month, nearly 100 blood drives across the country were canceled because of weather, resulting in a loss of more than 3,100 blood donations.

Hectic holiday schedules meant many regular donors were busy and the inclement weather together contributed to about 37,000 fewer donations in November and December than what was needed.

"The need for blood doesn't pause for severe weather - it's constant," said Bernadette Jay, external communications manager of the Mid-Atlantic Red Cross Blood Services. "Right now, blood and platelet donations are being distributed to hospitals faster than they are coming in. Eligible donors of all blood types are critically needed."

Every two seconds, someone in the U.S. needs blood. Accident and burn victims, heart surgery and organ transplant patients and patients receiving treatment for leukemia, cancer or sickle cell disease may all require blood to save their lives.

Eligible donors can schedule an appointment to donate by using the Blood Donor App, visiting redcrossblood.org or calling 1-800-RED CROSS.

The Red Cross is extending hours at many donation sites. Across the board, the Red Cross has added nearly 200 hours to blood donation centers and community blood drives across the country over the next few weeks.

Donation appointments and completion of a RapidPass online health history questionnaire can help speed up the donation process.
