READ THIS NEXT: USPS Is Making This Major Delivery Change, Starting Oct. 2. The Postal Service says it’s normal for a residence to not have any mail to deliver sometimes, but mail not showing up could also be a sign that the agency has removed services from your area. The USPS can suspend delivery for a number of reasons, and one issue has already caused several suspensions this year: mail carrier attacks. In June, the agency revealed that more than 5,400 postal employees in the U.S. were attacked by dogs in 2021 alone. That’s been a clear problem in 2022 as well. In May, residents in one Greenfield, Indiana, neighborhood were told the USPS would not reinstate delivery service “until residents install curbside mailboxes,” after loose dogs had left one carrier so injured she needed 50 stitches. In July, pit bull attacks in Des Moines, Iowa, also caused delivery to be suspended from a neighborhood. And that’s not the only reason the Postal Service might have to halt services. The USPS sometimes has no choice but to suspend its services in certain places.ae0fcc31ae342fd3a1346ebb1f342fcb Right now, “several post offices in Kentucky are closed due to flooding,” according to the agency’s website.

According to the news outlet, at least 37 people have died as a result of the conditions and rescue workers are still searching for missing individuals. Kentucky Gov. Andy Beshear said the current flooding in the state is “certainly the deadliest” he’s seen during his lifetime, noting that thousands of residents have been displaced because the flooding has hit roads, destroyed bridges, knocked out power, and swept away entire homes. The Postal Service has long warned customers that hazardous conditions or natural disasters may affect mail service. Earlier in August, the USPS was forced to suspend its services at several post offices in Northern California because of the McKinney Fire—a massive wildfire that broke out in the Klamath National Forest near the border of California and Oregon on July 29, per CNN Before that, the agency had to halt operations at its Processing and Distribution Center in St. Louis, Missouri, and close at least one post office in July, because of historic flooding in that city. “Flooding conditions presented some challenges for us, and we are reallocating resources, making every effort to provide delivery, however the safety of our employees is a top priority,” USPS spokesperson Mark Inglett told local Fox-affiliate KTVI .
