"The aircraft landed safely and customers exited normally through the main cabin door. Delta is making resources available to take care of and support our customers. We apologize for this experience as we work to get customers to Seattle," Compass Airlines said in a statement.

A Compass Airline official said the three injured on the flight were being transported to a hospital in Reno. The extent of their injuries is not known at this time.

The National Weather Service had warned earlier Wednesday that a strong winter storm moving into the region could create dangerous flying conditions with extreme turbulence.
