The Federal Environment Office has warned the risk of a forest fire outbreak is high to very high in several regions for the coming weekend.
Issuing the warning, the office said warm, dry temperatures were expected over the weekend.
The rainfall which occurred during the week had been too little to have much of an impact on generally dry conditions.
Southern Switzerland last week experienced a large forest fire near Visp.
Fire bans are in force in all cantons and total fire bans are in place in forest areas in 11 cantons.
