Shipping companies reported that the winter storm affected shipments ahead of the holidays

CHICAGO — Harsh winter weather conditions affected several major trucking companies with Christmas and the holidays approaching.

FedEx released a statement saying they are experiencing significant disruptions at their hubs in Memphis and Indianapolis due to severe weather that has created potentially hazardous working conditions.

UPS also said the weather affected its air and ground network, including its hub in Rockford, Illinois.

Amazon said some customer orders may be delayed due to inclement weather.

Tim Norman of the USPS said letter carriers are working around the clock to ensure that customers’ packages and letters reach their destinations by Sunday.

“We’re on the right track,” Norman said. “We’ll do our best while we can.”

All companies reiterate that the safety of their employees comes first, and if there is a delay, it will come as quickly as possible.

Shoppers WGN spoke with said they understand the fate of their packages is out of their control, and if they’re late, they said they’ll still have fun.

Friday is the last day to ensure that your USPS packages arrive under the Christmas tree via Priority Mail Express.
