The police were reached by the alarm at 16.20.
The avalanche is said to have occurred just west of Tyskhuvudet in Duved outside Åre.
- The avalanche is not something that anyone has witnessed, but it is an avalanche that has been discovered by a person who then notified Skistar.
Based on the information that has emerged, we can not rule out that someone has been dragged into the avalanche and therefore a search operation is initiated, says Johan Lindgren.
Mountain rescuers, ambulance, rescue service and police are in the area.
A total of about 30 people and two dogs are included in the search, according to SVT's reporter on site.
At around 7 pm, the police state that rescue personnel have searched an area of approximately 80x300 meters.
No person was found during the search, which continues during the evening.
- Right now they are trying to search through this avalanche to see if there is anyone in it, says Johan Lindgren.
At half past nine in the evening, the police state that they have completed the rescue operation.
- The assessment is that there are no people in the avalanche area after the search operation, says Johan Lindgren.
The Swedish Environmental Protection Agency has warned of significant avalanche danger in large parts of the Swedish mountain world this weekend, reports TT.
