caption_attribution_description: English: Track map of Severe Tropical Storm Pakhar of the 2017 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 Pakhar, known in the Philippines as Tropical Storm Jolina, was a strong tropical storm that impacted South China during late August 2017. This storm followed Typhoon Hato which affected the area a few days prior. Pakhar was the fourteenth named storm of the Pacific typhoon season. Pakhar developed from a tropical depression to the east of Luzon during August 24, and intensified into a tropical storm later that day. Pakhar made landfall over in Aurora on August 25. Pakhar gradually intensified and peaked as a severe tropical storm by August 27, making landfall over Taishan, Jiangmen in Southern China.
context_section_description: On August 23, the Joint Typhoon Warning Center (JTWC) started to monitor a tropical disturbance that had developed about 895 km (556 mi) to the north of the island of Palau. The next day, the Japan Meteorological Agency (JMA) classified the system as a weak tropical depression, while the JTWC issued a Tropical Cyclone Formation Alert (TCFA). Six hours after the TCFA, the JMA began issuing advisories on the depression after they have determined that the system contained winds of 55 km/h (35 mph). By 15:00 UTC of the same day, the JTWC had upgraded the system to a tropical depression, assigning the numerical designation 16W. Three hours later, the JMA tracked that 16W had already strengthened into a tropical storm, giving 16W the name Pakhar. Around the same time, the PAGASA began issuing advisories under the local name Jolina. After it was depicted by satellite imagery that there were deep convection obscuring its low-level circulation center (LLCC), the JTWC had upgraded the system to a tropical storm.
  By August 25, Pakhar slightly intensified after convective banding wrapping to its LLCC was depicted by imagery. Pakhar was also located in a very favorable environment such as low wind shear along with warm sea-surface temperatures of 31 °C (87.8 °F). Pakhar slightly intensified after a burst of deep convection developed just prior of making landfall over in Luzon in the province of Aurora. However, due to land reaction from the archipelago and the inclusion of a weakened convective structure, Pakhar weakened to minimal tropical storm intensity.
  After emerging to the South China Sea on August 26, Pakhar began to re-intensify as the storm entered in an area of a much lower amount of wind shear. However six hours later, Pakhar maintained its intensity after its LLCC became exposed and its deep convective banding became fragmented. By 18:00 UTC of the same day, the JMA upgraded Pakhar's intensity as a severe tropical storm, despite its central convection remaining disorganized. The PAGASA also stated that the storm had already exited their area of responsibility, issuing its final bulletin on Pakhar. By 00:00 UTC of August 27, Pakhar reached its maximum intensity of 100 km/h (65 mph) with a minimum barometric pressure of 985 hPa while making landfall over in South China in the city of Taishan. The JTWC assessed Pakhar's maximum intensity slightly higher with winds of 110 km/h (70 mph), however. Three hours later, the JTWC issued their final advisory. By 06:00 UTC, Pakhar began to rapidly weaken as the JMA downgraded Pakhar to a tropical storm. The JMA tracked the system until 18:00 UTC of the same day when it fully dissipated.
