Storm Front in Mayo

Ireland, June 1944. The crucial decision about the right time to start Operation Overlord on D-Day comes to depend on the readings taken by Maureen Flavin, a young girl who works at a post office, used as a weather station, in Blacksod, in County Mayo, the westernmost promontory of Europe, far from the many lands devastated by the iron storms of World War II.
