Netilat Yadayim in snow in the morning

Hi,

One may dip his hands in a snowbank for the ritual netilat yadayim upon rising in the morning, but one should dip them in three times, each time in a separate location.

This qualifies for the blessing of al netilat yadayim.

(Ishei Yisrael 2:19)

Have a great day,
Mordechai
