However, the East Coast is expected to face increasingly large swells and currents this week – with the Caribbean now affected. Several steering factors in the surface and upper levels of the atmosphere will determine how close Lee will come to the East Coast. If the jet stream forms along the east coast, it will act as a barrier to prevent the lee from approaching the coast. Lee may slowly turn northward as high pressure strengthens, and the jet stream sets inland over the eastern United States. This scenario leaves parts of the East Coast, mainly north of the Carolinas, vulnerable to a much closer approach from Lee.
