nor'easter Diagram map of the eastern United States and Atlantic Ocean showing the formation and development of a nor'easter. Blue arrows indicate cold, dry Arctic air moving south from Canada along the polar front jet stream, while red arrows show warm, moist air moving north from the Gulf of Mexico via the Gulf Stream. The map illustrates how these air masses interact off the U.S. East Coast, with labeled low-pressure systems developing along the coast and northeast winds affecting the region.
