Meteorological history
Hurricane John originated from a weak tropical wave that departed from the west coast of Africa and moved swiftly westward. Convection associated with the low-latitude wave remained within the Intertropical Convergence Zone before the system crossed South America on July 30. Around this time, the National Hurricane Center (NHC) first noted the possibility of tropical cyclogenesis several hundred miles south of the Gulf of Tehuantepec, forecasting the formation of an area of low pressure late that week. Aided by a positive phase of the Madden–Julian oscillation, thunderstorm activity associated with the disturbance began to increase as the system entered the eastern Pacific two days later.

Mexico
The combined effects of both Tropical Storm Ileana and Hurricane John generated heavy rainfall over the Mexican states of Jalisco, Colima, Michoacán, Guerrero, Puebla, Veracruz, Oaxaca, Sinaloa, and Nayarit. Heavy rains in Culiacán, Sinaloa alleviated drought conditions. The Junta de Agua Potable y Alcantarillado de Culiacán (JAPAC) delivered water pipes to communities affected by power outages to provide services.

While passing near Socorro Island, John produced sustained winds of around 55 mph (88 km/h) at a Mexican Navy observation site on the island. The same site recorded a peak wind gust of 80 mph (128 km/h) and a minimum pressure of 970 mbar (28.64 inHg), though the pressure recorded seemed to be four-to-five millibars too low. In Baja California Sur, state officials closed schools and ports as a precaution. A weakened Hurricane John brought large surf to the region.

United States
The large counter-clockwise flow of Hurricane John surged moisture into the Southwestern United States, producing torrential rainfall over the states of Arizona, Nevada, New Mexico, and into neighboring states between August 8–10, and lasting to August 11 in some areas.

Arizona
The influence of Hurricane John produced nightly rounds of severe weather across Arizona between August 8-10.

Elsewhere
In California, thunderstorms formed over eastern Riverside County on August 9, producing wind gusts of up to 60 mph (97 km/h) at the Blythe Airport. High wind caused by thunderstorms in Blythe caused dense dust storms along Interstate 10, lowering visibility to a quarter of a mile in some areas, dust storm warnings were posted for the area earlier that day. In nearby Imperial County, locally heavy rainfall developed in the eastern part of the county that generated rainfall rates of up to 1 inch (24.5 mm) per hour. Street flooding was reported along California State Route 78 by local police near Palo Verde. Along the coast of Southern California, large swells from Hurricane John brought rip currents and coastal flooding. Moisture from John also entered into Colorado. Moisture from Hurricane John in Texas also contributed to a thunderstorm in Dawson County, which produced a peak wind gust of around 62 mph (100 km/h) in Lamesa.
