Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. During this season, there is a former typhoon that crossed into central north Pacific. Systems Hurricane One Late on June 17, west-northwest of Acapulco and close to the coast of Mexico, an area of thunderstorms formed into a tropical cyclone. The system was very small, and eventually became a hurricane. It headed west-northwest or northwest, and was last detected early on June 18. A ship in the eye measured a pressure of 97.90 kPa inHg on.Weather on the North Pacific Ocean Monthly Weather Review 2011-01-18 Willis Hurd http://docs.lib.noaa.gov/rescue/mwr/068/mwr-068-06-0169.pdf June 1940 68 9 255–257 10.1175/1520-0493(1940)068<0255:WOTNPO>2.0.CO;2 1940MWRv...68..255H free Tropical Storm Two On July 20, a tropical depression was observed southwest of Acapulco. Historical Weather Maps show this depression near 17N 102W. It intensified into a tropical storm on July 21, tracked northwest, and dissipated on July 24. A depression/remnant low was tracked until July 26. The low was last seen near 24N 129W on the 27th. The lowest pressure reported by a ship was 100.66 kPa inHg on.Weather on the North Pacific Ocean Monthly Weather Review 2011-01-18 Willis Hurd http://docs.lib.noaa.gov/rescue/mwr/068/mwr-068-07-0196b.pdf July 1940 68 9 255–257 10.1175/1520-0493(1940)068<0255:WOTNPO>2.0.CO;2 1940MWRv...68..255H free Tropical Cyclone Three On July 29, a tropical cyclone was noticed. It traveled west-northwest or northwest, and dissipated sometime after July 30. A ship reported a pressure of 96.95 kPa inHg on. Tropical Cyclone Four South of Acapulco, a tropical cyclone was spotted on August 3. Historical Weather Maps (HWM) show a low on August 2 near 11N 109W. It rapidly tracked to the west-northwest, and was last seen on August 5. The low is carried on HMW until August 9 near 17N 135W. It is possible that this system retained tropical storm-force winds until approximately August 7.

It moved westward, and was lost track of on or after September 5.

The next day, it had intensified into a hurricane. By September 24, the hurricane was close to the Revillagigedo Islands. After that, no further observations were reported. A ship reported a pressure of 98.34 kPa inHg on in association with this hurricane. Tropical Cyclone Seven A tropical cyclone existed well out to sea from October 6 to 11. It traveled northwesterly, and had a lowest recorded pressure of 29.25 inHg kPa on.Weather on the North Pacific Ocean Monthly Weather Review 2011-01-18 Willis Hurd http://docs.lib.noaa.gov/rescue/mwr/068/mwr-068-10-0290.pdf October 1940 68 9 255–257 10.1175/1520-0493(1940)068<0255:WOTNPO>2.0.CO;2 1940MWRv...68..255H free Tropical Cyclone Eight Another tropical cyclone existed from October 26 to 28 off the coast of Central America. A ship recorded a pressure reading of 98.27 kPa inHg on. Tropical Cyclone Nine A tropical cyclone well southwest of Manzanillo was tracked from November 1 to 3. Due to a blocking area of high pressure, it took an unusual southwesterly track. Its lowest recorded pressure was 100.47 kPa inHg on.Willis Hurd Weather on the North Pacific Ocean Monthly Weather Review 2011-01-18 http://docs.lib.noaa.gov/rescue/mwr/068/mwr-068-11-0327.pdf November 1940 68 9 255–257 10.1175/1520-0493(1940)068<0255:WOTNPO>2.0.CO;2 1940MWRv...68..255H free Other system Around October 21, a former typhoon that had previously impacted Wake Island crossed into the central north Pacific.
