SAN FRANCISCO (CBS SF) – Red Cross officials report that severe weather across much of the country is expected to create a blood shortage.

Due to winter storm Hercules and deep snow and freeze across many parts of the north and east,  “the American Red Cross expects blood drive cancellations and low donor turnouts in these areas,” wrote Chief Medical Officer Dr. Richard Benjamin in a press release.

Donors in California and other unaffected areas are urged to help make up the donations in weather-impacted areas because the agency expects no drop-off in need.

The Red Cross directs people to visit their website or call 1-800-733-2767 to find a nearby donation location.
