Snow conditions 17.5.2019
17.05.2019
The danger level is 2 on the European 5-level scale - MODERATE.
Main problem: weak layers, wind slab, wet snow, new snow
Danger pattern: cooling after warm weather / warming after cold
Danger pattern: spring situation
Risk assessment
Avalanche danger is MODERATE, level 2, in high mountains above approx. 2000 m elevation, lower down mostly LOW, level 1. Steep slopes are particularly dangerous where wet snow avalanches may release during the day due to warming. In high mountains, wind slab areas remain hazardous where slab avalanches can be triggered primarily with increased snowpack loading.
Snow conditions
After cooling with snowfall it warmed up. Snow began settling and metamorphosing faster yesterday and melting rapidly especially in mid-elevations. Overnight, due to clearing, snow above approx. 1600 m refroze but will soften quickly during the day and metamorphose rapidly again. Numerous cornices especially on west and south sides of ridges and saddles. Wind-exposed spots are scoured.
Forecast weather evolution
Today variably cloudy, minor showers possible. Summits often foggy. Mostly light southerly winds. Slightly warmer, around 6°C at 1500 m, -1°C at 2500 m. Despite cloudy and foggy weather, sun's effect on snowpack occasionally significant. Saturday, Sunday and Monday predominantly cloudy with frequent precipitation, partly showers. More precipitation in western and southern Julian Alps. Snow line at 2100 to 2600 m elevation. Southerly winds strengthening somewhat. Around 7°C at 1500 m, around 0°C at 2500 m.
Trend in snow conditions
New snow settling and melting faster today. End of week and Monday: due to rain thaw, melting below 2200 m elevation somewhat faster. Due to rain thaw, small to medium wet snow avalanches possible especially on steep slopes. Above approx. 2400 m mostly snowing, 20 to 50 cm wet snow possible by Monday morning. Avalanche danger in high mountains remains MODERATE, level 2, for some time.
