Storm on the island

• "we are prepared"

  declarative statement gives a sense of confidence and arrogance that they can defend themselves from nature
• "Nor are there trees which might prove company when it blows full blast"

  trees are personified to keep company implying that nature and humans can sometimes work together

  onomatopoeia "Blast" implies the sheer power of the verb and the capitalisation reinforces the aggression

  alliteration of plosive sounds suggests the power of the natural storm mirrors the power of bullets used by humans showing how nature is just as powerful as humans
• "Spits like a tamed cat turned savage"

  simile shows how the sea has turned threatening

  contrast between "tame" and "savage" reflects how quickly events change

  cats can be domestic and wild to show nature can be kind and healing but also inflict suffering and chaos

  humans own cats but mankind has failed to tame nature, the islanders never owned nature as it was always more powerful than them
• enjambment reflects the constant barrage of the storm and the overwhelming effect and power nature has
• poems to compare:

  Ozymandias
