Which line from "The Leap" foreshadows what happens during the storm?

In "The Leap," the following quote foreshadows the storm:

"There came a rumble of electrical energy, drowned out by the sudden roll of drums."

This foreshadows the lightning that strikes the tent when Anna and Harry are performing. Specifically, this bolt of lightning hits the main pole as Harry is poised to catch Anna, causing him to topple forward and fall to the ground. Meanwhile, Anna realises that something is wrong and removes her blindfold so that she can see what is going on. She then changes the direction of her body and "twisted" towards a wire from which she is able to descend to the ground. Despite receiving burns to her hands, Anna saves her own life, though, tragically, she is unable to save the life of her unborn daughter.
In addition, the following line also foreshadows the storm:

"Winds generate instantaneously behind a hill and crash upon you without warning."

Through reference to the "crash," this line can be read as hinting both at the storm and the toppling of the tent as well as at the broken arm which Anna receives as the result of an over-zealous rescuer.
