The United States Postal Service is suspending mail delivery in 4 states on Wednesday, January 30, in response to the severe cold conditions related to the Polar Vortex and Winter Storm Jayden. The Postal Service has a reputation for delivering in virtually any weather conditions, no matter how severe, but the record cold temperatures associated with the polar vortex prove to be too severe to be safe for letter carriers.

According to a release from the USPS, delivery operations in the following areas will be suspended for Wednesday, January 30:

Minnesota

Western Wisconsin

Iowa

Western Illinois

Local offices and retail operations may still be available, but only in a limited capacity. The suspension means there will be no mail pick up from businesses, collection boxes, residential locations, and package pickup services.
