Avalanches
In the summer and autumn, avalanche bulletins are published only in the event of heavy snowfall. Even if the SLF does not publish an avalanche bulletin, due consideration is to be given to the avalanche situation especially if snow has fallen recently.
Keep informed about the publication of unannounced Avalanche Bulletins. Activate in the App WhiteRisk the "Push Summer Bulletin".
The regular publication of avalanche bulletin recommences in November/December.14:Avalanches:-1:SLF:1111,1112,1113,1114,1121,1122,1211,1212,1213,1221,1222,1223,1224,1225,1226,1227,1228,1231,1232,1233,1234,1241,1242,1243,1244,1245,1246,1247,1311,1312,2111,2112,2121,2122,2123,2124,2131,2132,2133,2134,2211,2212,2221,2222,2223,2224,3111,3112,3113,3114,3211,3221,3222,3223,3224,3311,4111,4112,4113,4114,4115,4116,4121,4122,4123,4124,4125,4211,4212,4213,4214,4215,4221,4222,4223,4224,4225,4231,4232,4241,4242,4243,4244,5111,5112,5113,5121,5122,5123,5124,5211,5212,5214,5215,5216,5221,5222,5223,5231,5232,5233,5234,6111,6112,6113,6114,6115,6121,6122,6131,6132,6211,6212,7111,7112,7113,7114,7115,7121,7122,7123,7124,7125,7126,7211,7221,7222,7231,8111,8112,8113,8114,8211,8212,8213,8214,8215,8216,8221,8222,8223,8224,8225,8226,8227,8228,9111,9211,9311:
