An estimated 6.2 million Florida residents are without power Monday due to powerful winds and flooding related to Hurricane Irma. In response to the devastation, Pittsburgh-based organizations are sending troops to Florida to help with restoration.

Volunteers and rescue workers from the Pittsburgh area are making their way south to help flood victims in Texas.

The American Red Cross Blood Services provides about 40 percent of the blood used in transfusions across the country. In honor of Black History Month, the organization is urging people of all ethnic groups to donate blood.

“Blood from a donor with a similar ethnic background as that of the patient is less likely to cause complications, particularly for patients whose chronic conditions require repeated transfusions,” said Marianne Spampinato, spokeswoman for the American Red Cross Greater Alleghenies Blood Services Region.

One of the last things people might think about on a beautiful summer day is giving blood, and the American Red Cross is starting to notice that the drop in donations could be serious.

Blood donations have decreased by 8 percent over the last 11 weeks meaning that the Red Cross is down by approximately 80,000.

“This shortfall is significant enough that without increased donor turnout we could experience an emergency situation in coming weeks,” said Marianne Spampinato, Red Cross’s External Communications Manager.
