The 'morse code lightning bolts' are perfection. I can not think of a more wonderful and seemingly true metaphor for lightning sending out an S.O.S or perhaps a warning to those who dare to gaze upon its beauty.
ooo, i like this one! i could see it, the lightning bolt like a sword through the sky. wonderful little haiku you one-armed bandit you! the rains are coming soon, and here in Washington, they flow for days and days... makes everything so green and lush. much love, ~Cat
Tiff- Well done, nice to see you doing Haikus. The last line seemed a little week, perhaps "Rain's sky tears open"? Just my humble input. However you present it, the imagery is there and easy to understand.
