Updated at 4:57 p.m. ET: An avalanche buried and seriously injured the second son of Dutch Queen Beatrix while he skied off marked trails Friday in the westernmost corner of Austria and he was rushed to the intensive care unit of an Innsbruck hospital, officials said.
The Dutch government, which initially said 43-year-old Johan Friso's life was in danger later issued an update saying "his condition is stable but not out of danger."
"Her Majesty the Queen and (Friso's wife) Princess Mabel are with Prince Friso," the Dutch statement said, adding that "doctors treating him will only be able to give a prognosis in a matter of days."
Stefan Jochum, a spokesman for the Lech ski area where the accident occurred, said Friso's condition was serious but his life was no longer at risk.
Jochum said the accident happened early Friday afternoon as the prince and other skiers were on slopes away from marked Lech ski runs and laden with snow after weeks of record falls.
The Lech municipal office said a regional avalanche warning issued for the day was four on the five-point scale, meaning the danger was high.
"A snow slide came down and the prince was buried as the only member of the group," said Jochum in a telephone interview. A rescue helicopter was on the scene within minutes, and after Friso was located, he was resuscitated on the scene and flown to the hospital, Jochum said.
The Austria Press Agency earlier cited Lech Mayor Ludwig Muxel as saying Friso was buried for about 20 minutes by a snow mass that measured more than 30 yards by 40 yards when it hit him.
Friso was in Lech with other members of the royal family. Friso, the second of Beatrix's three sons, married Dutch commoner Mabel Wisse Smit, in 2004. The pair have two daughters, Countess Luana, 6, and Countess Zaria, 5.
Most recently Friso has worked as financial director at Urenco, the European uranium-enrichment consortium.
The crucial moment in his life as a member of the Dutch nobility came with his 2003 engagement to then-commoner Wisse Smit.
After the pair announced their intention to marry in 2003, Dutch media revealed that Wisse Smit's previous friendships included contacts while she was in college with a well-known figure in the Dutch underworld, a drug dealer who was later slain.
The couple publicly acknowledged having been "naive and incomplete" during her vetting process before joining the royal family. Then-Prime Minister Jan Peter Balkenende signaled he could not recommend the marriage to parliament for approval.
They married anyway, a decision that meant Friso's removal from the line of succession.
The couple are still part of Beatrix's family and attend important royal functions. Mabel has been granted the title "Princess Mabel" and Friso has an array of noble titles, including "Prince of Oranje-Nassau" — but not "Prince of the Netherlands."
