At 21:00 UTC (GMT+10) on the same day, the Joint Typhoon Warning Center (JTWC) began tracking the system, giving it the identifier 17W.{{cite web|title=Tropical Depression 17W (Seventeen) Warning Nr 001|url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201808022100.htm|archive-url=https://archive.today/20240523131355/https://www.webcitation.org/71OkfsOzG?url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201808022100.htm|url-status=dead|date=August 2, 2018|archive-date=May 23, 2024|publisher=Joint Typhoon Warning Center}} 17W intensified into a tropical storm on August 3, with the Japan Meteorological Agency assigning it the name Shanshan.{{cite web|title=Tropical Storm 17W (Shanshan) Warning Nr 003|url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201808030900.htm|archive-url=https://archive.today/20240523131311/https://www.webcitation.org/71Okf8Fn4?url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201808030900.htm|url-status=dead|date=August 3, 2018|archive-date=May 23, 2024|publisher=Joint Typhoon Warning Center}} The storm was located over a favorable environment as the system was gradually consolidating,{{cite web|title=Prognostic Reasoning for Tropical Storm 17W (Shanshan) Warning Nr 04|url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201808031500.htm|archive-url=https://archive.today/20240523131438/https://www.webcitation.org/71PkKoqiL?url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201808031500.htm|url-status=dead|date=August 3, 2018|archive-date=May 23, 2024|publisher=Joint Typhoon Warning Center}} and it intensified into a severe tropical storm on August 3. The following day, both the JMA and JTWC upgraded Shanshan to a typhoon after deep convection was seen wrapping into its developing center. The JMA later determined that the storm had peaked in intensity with 10-minute winds of 130  km/h (80  mph) and a minimum pressure of 970 hPa, and expected the storm to maintain that intensity for several days. The JTWC stated that Shanshan had slightly weakened after a strengthening trend by August 6 after its eye became ragged and slightly displaced. On August 7, Shanshan began to re-intensify and reached its peak strength as a Category 2 typhoon with 1-minute winds of 165  km/h (105  mph) while nearing southeastern Japan. Thereafter, Shanshan began to change course towards the east as it rapidly weakened. The JTWC issued their final advisory on August 9, although the JMA tracked the system until it became extratropical at 06:00 UTC on August 10.
