FORT COLLINS, Colo. (AP) - Colorado State University forecasters say a hurricane in the Gulf of Mexico could affect the direction of the oil spill, but they say little is known about the interaction between storms and oil.

Forecasters Phil Klotzbach and William Gray said Wednesday if a hurricane goes west of the spill, the storm's counter-clockwise flow could push some of the oil to the U.S. coast. A storm east of the spill could send the oil farther offshore.

They made similar projections in June.

The forecast they released Wednesday calls for 10 Atlantic hurricanes this season, five of them major. That's also unchanged from their June forecast.

Klotzbach and Gray say they expect this year's season to be more active than average.
