I was so sure a thunderstorm would break loose above my head any minute. Though I was  out at sea and there was just a slight wind blowing through my hair, I was constantly watching the sky, waiting for the first lightning bolt to hit the land ahead of me. 

Because I was watching the sky so intensely, I didn’t notice how the water behind me was forming itself into a tidal wave.

(I still thought it was going to thunder when I woke up.)
          ((The forecast says it is going to thunder today.))
