Kentucky Blood Center is struggling to build up a blood supply that's been greatly reduced by Old Man Winter.
More than 20 blood drives have cancelled this week, resulting in nearly 400 lost blood donations, according to KBC.
The non-profit says donor center donations were also hit, with the Somerset donor center unable to open Monday because of hazardous road conditions.
The harsh weather has caused recurring blood supply problems this winter. KBC says that since the first of this year, nearly 70 blood drives have canceled causing the loss of more than 1,700 donations.
KBC is urging the public to visit one of their blood drives or donor centers as soon as possible to bring the blood supply back to normal levels so blood is readily available for patients who need it.
Blood donors must be 17-years-old (16 with parental consent), weigh at least 110 pounds, be in general good health, show a photo I.D. and meet additional requirements. Sixteen-year-old donors must have a signed parental permission slip.
