English: Tropical Storm Dumile formed at the beginning of 2013 in the southern Indian Ocean, east of Madagascar. The storm moved southward as it strengthened into a tropical cyclone. On January 3, 2013, the U.S. Navy’s Joint Typhoon Warning Center (JTWC) reported that Dumile was located roughly 85 nautical miles (155 kilometers) northwest of Réunion. The storm had maximum sustained winds of 65 knots (120 kilometers per hour) and gusts up to 80 knots (150 kilometers per hour).

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image on January 3. Dumile’s clouds extended over the islands of Réunion and Mauritius but stopped short of Madagascar’s capital city of Antananarivo.

The JTWC forecast that Dumile would continue moving southward before accelerating toward the southeast. Storm wind speeds were expected to gradually decrease over the next few days.
