Raising storms of disheveled, greyish locks, With a thunderous roar, O Time, arise! - from the North.

This couplet paints a vivid picture of powerful, turbulent winds, like dusty, wild locks being stirred into a storm. It's a dramatic call to a mighty force, perhaps personified as Time or a formidable entity. The lines command this power to 'Rise!' from the northern direction, accompanied by a roaring or howling sound. The imagery evokes a sense of an immense, untamed force gathering on the horizon, hinting at significant, perhaps overwhelming, change or impact. It's an invocation of a grand, almost natural or supernatural event about to unfold.
