A developing tropical system, potentially Hurricane Imelda, is heading towards the Carolinas, posing a risk of heavy rainfall and flooding early next week. Its path and intensity may be influenced by a larger, older hurricane, Humberto, through a rare "Fujiwhara Effect" interaction. Meteorologists are closely monitoring this unusual "dance" which could steer Imelda out to sea, but the outcome remains uncertain, with high stakes for the Southeast coast.
