According to a report from First Coast News, 

OneBlood announced that it urgently needs local blood donations to help Hurricane Harvey victims

Why is it so urgent and why US? Rising flood waters and destruction is preventing blood centers in Texas from collecting blood! So OneBlood is asking for help in collecting local donations.

The center said it sent nearly 300 units of blood during the past 2 dayss and plans to supply blood to Texas until further notice.

NEEDS:

All blood types are needed, but there's an urgency for O negative and O positive blood.
ALSO NEEDED: platelets and plasma donations 

Healthy people ages 16 or older can donate and must weigh at least 110 pounds.
