As this post points out:
There are two blessings to choose from upon witnessing extraordinary natural phenomena—including extremely strong winds.
Those two blessings (of which only one may be said on each occasion) are:
Baruch Atah Ado-nai Elo-hei-nu Melech haolam, osay ma’asei bereisheet.
Translation: Blessed are You, L‑rd our G‑d, King of the universe, Maker of the works of creation.
Baruch Atah Ado-noi Elo-hei-nu Melech haolam, shekocho ugevurato malei olam.
Translation: Blessed are You, L‑rd our G‑d, King of the universe, whose power and might fill the world.
Hurricanes and other extraordinary natural phenomena make Hashem’s presence and control quite clear.
What lessons did you learn from hurricane Sandy?
What were you thankful for after the storm?
Were any hashkafic insights discovered?
