wind shift

Should also the wind shift, we should lose more of our sails, and might be driven before daylight helplessly on shore.

Musing, I sat, watching the crew on board the yacht making preparations for our departure, should the wind shift fair.

About nine o'clock the wind shift to the northeast, and everything froze hard.

Should the wind shift back to its old quarter, however, there was a fair probability that the boat would overtake her.

It looked very much to me as though the clouds might break and the wind shift, or lull, at any moment.
