The 2018 Pacific typhoon season was at the time, the costliest Pacific typhoon season on record, until the record was beaten by the following year. The season was well above-average, producing twenty-nine storms, thirteen typhoons, seven super typhoons and six Category 5 tropical cyclones. The season ran throughout 2018, though most tropical cyclones typically develop between May and October. The season's first named storm, Bolaven, developed on January 3, while the season's last named storm, Man-yi, dissipated on November 28. The season's first typhoon, Jelawat, reached typhoon status on March 29, and became the first super typhoon of the year on the next day.

Severe Tropical Storm Ampil, known in the Philippines as Severe Tropical Storm Inday, was a tropical cyclone that caused moderate damage in the Ryukyu Islands and East and Northeast China in late July 2018. The tenth named storm of the annual typhoon season, Ampil developed into a tropical depression east of Luzon on July 17. The system gradually strengthened over the following days amid a marginally favorable environment and became a severe tropical storm late on July 19 as it moved northwest. Maintaining its strength, Ampil passed over Okinawa Island from July 20 to 21. Thereafter, Ampil weakened slightly while crossing the East China Sea, before making landfall in Shanghai, China, on July 22. The system weakened slowly over land and degraded to a tropical depression on July 23. The system turned eastwards as it continued weakening over land, diminishing to a remnant low on July 25 and dissipating fully a day later over the Russian Far East.

This timeline documents all of the events of the 2024 Pacific typhoon season. Most of the tropical cyclones form between May and November. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. Tropical storms that form in the entire Western Pacific basin are assigned a name by the Japan Meteorological Agency. Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center. In addition, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones that enter or form in the Philippine area of responsibility. These names, however, are not in common use outside of the Philippines.

Typhoon Ampil was a powerful tropical cyclone that brushed Japan and brought torrential gusty winds to Alaska in early August 2024. The seventh named storm and third typhoon of the annual typhoon season. Ampil emerged from an atmospheric convection east of Kadena Air Base and was later classified as a tropical storm on August 12 and named Ampil by the Japan Meteorological Agency. Ampil gradually intensified as it turned northward, reaching its peak intensity with ten-minute sustained winds of 155 km/h (100 mph) and a central pressure of 950 hPa (28.05 inHg) before peaking at Category 4-equivalent intensity on the Saffir–Simpson scale on August 16, with one-minute sustained winds of 215 km/h (130 mph) before making its closest approach to Japan. It then rapidly weakened as it began to undergo an extratropical transition on August 19. The remnants of Ampil accelerated east-northeastward, entering the Bering Sea, crossing the Aleutian Islands in Alaska, and then moving inland over the Russian Far East and Arctic Alaska before emerging into the Arctic Ocean and dissipated on August 23.
