The U.S. Postal Service urged any voters with absentee ballots to mail them as soon as possible, but assured customers that political mail would still be processed in a timely manner despite Hurricane Sandy.

"Conditions in areas affected by Sandy will continue to change, but in general, the Postal Service has procedures in place to expedite recovery efforts, including making sure there is timely delivery of mailed ballots," USPS spokesman Dave Partenheimer said in an e-mail. "We continue to urge voters in the contiguous United States to mail completed absentee ballots at least three days before the Nov. 6 general election -- or Nov. 3."

Local managers were given discretion on whether to send letter carriers out into the weather, Partenheimer said, and several exercised caution. Post offices along the North Carolina, New Jersey and New York coastlines closed or suspended deliveries Monday as the storm approached. FedEx, which flies a considerable amount of the Postal Service's mail across the country, also said it was suspending or curtailing flights to certain East coast cities, including New York, Boston, Philadelphia, Baltimore and D.C., likely delaying the arrival of millions of packages and envelopes.

Local managers will once again have discretion on whether to open operations Tuesday along the storm's projected path.
