June 1 marks the official beginning of hurricane season, even though we've technically already had one named storm. I searched for some preventing disastrous storm prayers and came up with these. The first is pretty generic and the second is very Catholic (and kind of scary).
Father, all the elements of nature obey your command.
Calm the storms and hurricanes that threaten us
and turn our fear of your power into praise of your goodness.
O God, Master of this passing world, hear the humble voices of your children. The Sea of Galilee obeyed your order and returned to its former quietude; you are still the Master of land and sea. We live in the shadow of a danger over which we have no control. The Gulf, like a provoked and angry giant, can awake from its seeming lethargy, overstep its conventional boundaries, invade our land and spread chaos and disaster. During this hurricane season, we turn to You, O loving Father. Spare us from past tragedies whose memories are still so vivid and whose wounds seem to refuse to heal with the passing of time. O Virgin, Star of the Sea, Our Beloved Mother, we ask you to plead with your Son in our behalf, so that spared from the calamities common to this area and animated with a true spirit of gratitude, we will walk in the footsteps of your Divine Son to reach the heavenly Jerusalem where a storm-less eternity awaits us. Amen.
