The functions which in the Canaanite pantheon are shared out among a wide variety of deities are for the Israelites concentrated in Yahweh; in the Ugaritic texts Asherah walks on the sea and Baal rides on the clouds, but in the Old Testament it is Yahweh who does both:

He plants his footsteps in the sea,
And rides upon the storm.
