In the mountains, you need to be careful of avalanches.
This year the risk of avalanches is high.
Standard kanji spelling; the repetition of 雪 is unusual but attested.
Rarely used kanji form; the second character 傾 is not standard for this word.
Compound of 雪 (snow) and 雪崩 (avalanche), literally 'snow avalanche'. The repetition of 雪 is unusual but serves to emphasize the snow component.
