Telltale signs of seasonal changes are evident around the seaside landscape. Coastal nature tells the story of winter’s approach on this northeast Florida barrier island. It’s been flurrying around Amelia Island, especially near Egans Greenway in Fernandina Beach. Anyone who’s been along Jasmine Street between the beach and Citrona Avenue has seen the white flurries floating on the breeze, crossing from one side of the Greenway to the other.  A sea island’s “snow.”
