After a week of snow, rain, wind and near flooding, the post office might want to reconsider its unofficial creed.

You know, the one suggesting that “neither snow nor rain nor heat nor gloom of night” will stop the flow of mail.

For people in South Buffalo and the Southtowns, four to five days without home delivery put that old saying – it’s an inscription on a landmark post office in Manhattan – to the test.

“The weather may have disrupted mail service last week, but with the tenacity of our postal employees and the resilience of our communities, we expect it to be ‘business as usual’ in the next couple days,” James K. Lentz, Western New York manager for the U.S. Postal Service, said in a statement Monday.

The Postal Service resumed normal mail delivery to the region’s snow-ravaged areas Monday, but officials acknowledged that some deliveries may still be suspended.

Chief among them are residents whose mailboxes were “lost” to a plow or are still buried under snow.

Postal officials said that those people should place a “temporary hold” on their mail by going to their local post office or and clicking on the “Hold mail” link.

“It’s still possible there may be streets we can’t get down or mail boxes still buried under snow,” said Postal Service spokeswoman Karen Mazurkiewicz.

Mazurkiewicz said the delays in mail service stemmed from more than just a lack of access to people’s mailboxes. She said a lot of out-of-town mail intended for Erie County never made it here last week because of problems with mail trucks getting through the snow-clogged Thruway and other major roadways.
