Pacific typhoon seasons
1948, 1949, 1950, 1951, 1952

The 1950 Pacific typhoon season has no official bounds; it ran year-round in 1950, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1950 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the North Pacific Typhoon Warning Service.

Typhoon Jane struck the island of Shikoku in Japan on the 3rd of September. Resulting flooding and landslides killed 539 people. [1]

In late August, a depression formed and quickly intensified into a tropical storm and was given the name Jane. The storm drifted west-northwestward and intensified into a typhoon. Jane gradually curved to the north and intensified to a category 2 typhoon. Jane shortly reached category 3 status and peak intensity at 185 kph (115 mph). The typhoon accelerated to the north-northeast and weakened to a category 2 storm and made landfall in the modern-day Osaka-Kobe-Kyoto area. Jane crossed Kyoto Prefecture and weakened to a tropical storm and crossed the Noto Peninsula and reentered the Sea of Japan and passed just west of Sado Island. The storm struck eastern Aomori Prefecture and crossed the Tsugaru Straits and made a final landfall on the south coast of Hokkaido Prefecture. Jane crossed Hokkaido and dissipated south of the Kuril Islands.
