High winds are grounding the Civil Air Patrol's search for Steve Fossett today.
Spokeswoman Maj. Cynthia Ryan said that the air search will be suspended for the volunteer organization for safety reasons.
Winds of up to 50 mph are expected off the Sierra ridgetops today.
Meanwhile, National Guard and private aircraft will continue to look for the famed aviator who failed to return to the Flying M Ranch on Labor Day.
