Cotton futures dropped when the U.S. cotton crop's progress showed improvement as rains have come to Texas, the largest growing region.

Cotton for December delivery fell 1% to end at 66.29 cents a pound on the ICE Futures U.S. exchange.

"For now, the growing areas look good," said Jack Scoville, vice president of Price Futures Group in Chicago.

Traders are watching a variety of developing storms that could impact areas in the Delta and Southeast Texas and are also closely following the development of crops in the southern and western Great Plains, where hot and dry weather has stressed crops.
