The 1942–48 Pacific hurricane seasons all began during late spring in the northeast Pacific Ocean and the central Pacific. They ended in late fall.
Before the satellite age started in the 1960s, data on east Pacific hurricanes is extremely unreliable. In a few years, there are no reported cyclones although many systems certainly formed.
A disturbance developed between the Revillagigedo Islands and the Marias Islands on October 8. It moved rapidly northeastward where it rapidly intensified, reaching pressures as low as 95.86 kPa (28.31 inHg). On October 9, as a major hurricane it struck the west coast of Mexico, a short distance south of Mazatlán. The next day, the hurricane dissipated inland.[1]
This hurricane caused damage in and around Mazatlán. It sank several vessels. The total cost of damage was $4,500,000 (1943 US dollars), and at least 106 people were killed.[1]
A hurricane dissipated off the northern coast of the Baja California Peninsula. Its remnants moved northeast, and they brought rain to California on September 9 and 10.[2]
A tropical depression, a continuation of Atlantic Hurricane 10, entered the Pacific Ocean on October 5.[3] A circulation center associated with this cyclone moved along the Mexican coast, and remained recognizable until it was west of Acapulco. It caused heavy rain along its path.[4]
A hurricane made landfall on the northern Baja California Peninsula. It dissipated over northern Baja California. Its remnants headed north, where they brought rain to the mountains of southern and central California on September 30 and October 1.[2]
