USPS Lists Possible Mail Delays in Several Regions
The U.S. Postal Service is still listing possible delays to mail and package processing, transportation and delivery in several U.S. regions as of Monday, Sept. 14, 2026.
The USPS national service-alert page says it was last updated Sept. 11, 2026, at 3:30 p.m. ET. The notices are regional and do not mean delivery has stopped nationwide or that every customer in an affected state will experience a delay.
Where USPS lists possible delays
USPS lists separate weather-related or natural-disaster impacts in four areas:
- Hawaii: Impacts from Hurricane Lowell may delay mail and package processing, transportation and delivery.
- Utah and Arizona: Flooding in the Southwest may affect postal operations.
- Southern California: Tropical storms off the California coast may delay processing, transportation and delivery.
- Arkansas, Mississippi, Tennessee and Kentucky: Severe weather in the Mid-South may affect postal operations.
USPS does not describe these notices as one nationwide disruption. The listed causes differ by region, and the operational status may change as facilities, transportation routes and local delivery conditions are updated.
The separate USPS residential-disruptions page also shows location entries with different dates, including Hawaii on Sept. 10 and California on Sept. 8. That means customers should rely on the current status for their location rather than assume every entry was posted at the same time.
How to check whether your mail is affected
USPS directs residential customers to its current delivery-issues information for frequently updated details about whether mail is being delivered in a neighborhood and whether a local Post Office is open. Check that information before traveling to send or collect mail.
For packages, use USPS Tracking before assuming an item is lost. USPS says tracking provides the current available status and may show delivery or attempted-delivery information, but tracking does not expedite or guarantee delivery.
If a package or mailpiece remains late or appears stalled, USPS provides a Missing Mail or package process for additional help. Customers can also use Informed Delivery to preview incoming mail and manage packages scheduled to arrive, when the service is available for their address.
Options when delivery or access is difficult
Customers who cannot safely receive mail or reach a mailbox can use USPS Hold Mail. USPS says online Hold Mail requests can be scheduled for a minimum of three days and a maximum of 30 days, subject to its account and timing requirements.
It is also wise to verify a Post Office’s operating status before traveling. For help with a delivery disruption, USPS lists its customer-service number as 1-800-ASK-USPS, or 800-275-8777.
Weather conditions remain uneven
The National Weather Service separately says heavy to excessive rainfall could bring flooding at times from Monday through Thursday across parts of the central Plains and Midwest, as well as southern Arizona and New Mexico. That is broad federal weather context, not proof that every USPS alert is caused by the same weather system.
The Hawaii notice should likewise be treated separately from the continental alerts. USPS identifies Hurricane Lowell as the cause of that regional notice, while the other alerts cite flooding, tropical storms or severe weather in their respective areas.
USPS service alerts are live operational notices and may change. Customers with time-sensitive documents, prescription deliveries or important packages should check the current USPS alert page, local delivery-issues information and tracking status before making plans.
