NEW YORK (AP) — Some gifts that were supposed to be under the tree this morning won't be arriving until tomorrow or later.

UPS and FedEx say they've run into some shipping problems in parts of the country this week -- in some cases because of poor weather, but also because of overloaded systems.

UPS isn't making any pickups or deliveries today, and plans to resume normally scheduled service tomorrow.

Neither company said how many packages were delayed but noted it was a small share of overall holiday shipments.
