Tropical Cyclone Gelane had sustained winds of 125 knots (230 kilometers per hour) and gusts up to 150 knots (275 kilometers per hour), according to a report from the U.S. Navy’s Joint Typhoon Warning Center (JTWC) on February 19, 2010. The JTWC reported that Gelane was roughly 315 nautical miles (585 kilometers) east-northeast of Port Louis, Mauritius, and was forecast to travel toward the southwest, weakening slightly as it moved.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this true-color image on February 19, 2010. Gelane’s spiral arms span hundreds of kilometers over the open ocean.
