Four days before Hurricane Irene struck eastern North Carolina and tracked northward, NOAA's National Hurricane Center accurately projected the storm's path. Even before then, forecasts showed that Irene would threaten the East Coast. This satellite animation shows Irene's progress across the western Atlantic and how it followed the National Hurricane Center's track issued at 11pm ET on Tuesday, August 23 (Advisory # 15).
