Blood supplies in Iowa are at a critical low and donors are being urged to schedule immediate appointments or just walk in to the nearest blood center to donate. Hurricane Dorian is beginning its trek up the East Coast and Danielle West, spokeswoman for LifeServe Blood Center, says all blood types are needed for donations.

To schedule an appointment, call 800-287-4903 or visit www.lifeservebloodcenter.org.
