The U.S. orange crop is expected to fall 14 percent from last year because of an unusual freeze in Florida this winter.

The U.S. Department of Agriculture said Tuesday the orange harvest will be down 21 percent in Florida compared to last year's yield. The national harvest this year will be close to 8 million tons, with 5.8 million coming from Florida.

The USDA cut its forecast after eight days of subfreezing temperatures hit the Southeast in early January.
