News Alert
Winter storms across the Midwest have created hazardous road conditions that are now affecting USPS operations. In a new industry alert, the USPS announced unload delays at major processing facilities in Kansas City, MO and Louisville, KY, which may impact mail movement through December 5.
What the USPS Shared in Its Alert
According to the USPS, recent snow events caused extended road closures earlier this week, resulting in a buildup of inbound trailers at both affected facilities. With higher-than-normal volume arriving in a short window, these locations are now experiencing delays unloading incoming mail trucks.
The USPS advised that drop ship customers may see longer wait times and should continue reporting significant issues through the FAST Helpdesk. They also noted active efforts to reduce congestion, including staffing adjustments, scheduled offloads, and alternative drop-site arrangements.

Alternate Entry Locations Recommended by USPS
To keep mail moving, the USPS suggested that customers entering mail at origin consider temporarily using alternate locations.
Kansas City, MO Alternate Sites
- Oklahoma City, OK Processing & Distribution Center — NASS 730
- Des Moines, IA Network Distribution Center — NASS 50Z
Louisville, KY Alternate Sites
- Springdale, OH Annex — NASS 452AX
- Memphis, TN Processing & Distribution Center — NASS 380
These sites may help relieve pressure on the two impacted facilities until weather-related backlogs improve.
