caption_attribution_description: English: Track map of Tropical Storm Vamco of the 2015 Pacific typhoon season. The points show the location of the storm at 6-hour intervals. The colour represents the storm's maximum sustained wind speeds as classified in the Saffir–Simpson scale (see below), and the shape of the data points represent the nature of the storm, according to the legend below.

context_page_description: Tropical Storm Vamco was a weak tropical cyclone which affected Indochina in mid-September 2015. Formed from a tropical disturbance on September 13, the system developed into a tropical storm and reached its peak intensity on September 14. Vamco made landfall in Vietnam and affected Laos, Thailand and Cambodia. The storm caused flooding in these countries and damages amounted to US$14.1 million. Fifteen people died in the floods.
  In Vietnam, Vamco was known as known as Cơn bão số 3 năm 2015. Heavy rains caused by the storm in Central Vietnam ended the drought in this area, after many hot days because of the strong El Niño.
context_section_description: The system that was to become Tropical Storm Vamco was first noted as a tropical disturbance during September 11, while it was located over the South China Sea, about 555 km (345 mi) to the west of Manila in the Philippines. At this time fragmented bands of atmospheric convection were trying to form around the system's low level circulation centre, which was located within a marginal environment for further development. Over the next couple of days the system gradually developed further, before it was classified as a tropical depression during September 13, by both the Japan Meteorological Agency and the United States Joint Typhoon Warning Center. With flaring deep convection surrounding its LLCC, the JTWC started issuing bulletins and was assigned the designation 19W. Thereafter, both the JMA and the JTWC upgraded 19W to a tropical storm, naming it Vamco. On September 14, deep convection slightly weakened and became displaced near its center, however the environment was still favorable at this moment. A few hours later, the JTWC reported that according to animations, the center of Vamco had become partially exposed and wind shear inhibited further development, which favorable conditions started to fade. Therefore, the JTWC issued its final warning. Vamco made landfall south of Da Nang, Vietnam, and the system was last noted as it dissipated over land on September 15.
