A strengthening Cyclone Olaf and a weakening Cyclone Nancy eye each other across the South Pacific in this Moderate Resolution Imaging Spectroradiometer (MODIS) image from February 15, 2005. As of the afternoon of February 15, Olaf was approaching Category 5 status, with sustained winds of 135 knots and gusts up to 165 knots. According to the Joint Typhoon Warning Center, waves were estimated to be as high as 47 feet. Although Nancy was a Category 4 storm in its early stages, by February 15, the storm had weakened. Sustained winds were 85 knots, with gusts up to 115 knots. Wave heights could be as high as 27 feet. Unlike Olaf, Nancy was predicted to weaken as it moved south over subsequent days.
