The 1992 Pacific typhoon season is the fourth consecutive above-average season, producing 31 tropical storms, 16 typhoons and five super typhoons. It had no official bounds; it ran year-round in 1992. Despite this, most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

Typhoon Omar of 1992, known in the Philippines as Typhoon Lusing, was the strongest and costliest typhoon to strike Guam since Typhoon Pamela in 1976. The cyclone formed on August 23 from the monsoon trough across the western Pacific Ocean. Moving westward, Omar slowly intensified into a tropical storm, although another tropical cyclone nearby initially impeded further strengthening. After the two storms became more distant, Omar quickly strengthened into a powerful typhoon. On August 28, it made landfall on Guam with winds of 195 km/h (120 mph). The typhoon reached its peak intensity the next day, with estimated 1‑minute winds of 240 km/h (150 mph), making it a "super typhoon" according to the Joint Typhoon Warning Center (JTWC). Omar weakened significantly before striking eastern Taiwan on September 4, proceeding into eastern China the next day and dissipating on September 9.
