Dora's annular structure deteriorated, leaving the system susceptible to dry air intrusions, and the hurricane passed south of Johnston Island.

The same day, southerly shear degraded the hurricane's structure as it shifted its course toward the west-northwest along the southwest edge of a high pressure system.

Hurricane Dora's origins can be traced to a tropical wave that crossed over Central America into the Eastern Pacific on July 29, off the coast of El Salvador, producing a large area of rain and thunderstorms amid a favorable environment.

[3] Deep convection increased and the depression achieved tropical storm status by 09:00 UTC on August 1; the National Hurricane Center (NHC) assigned it the name Dora accordingly.

[4] During August 2–3, Dora rapidly intensified to Category 4 strength, far to the southwest of Cabo San Lucas, Baja California Sur.

[9][10] Later, on the morning of August 9, Dora strengthened once again, generating winds of 145 mph (230 km/h) amid a low-shear, warm sea surface temperatures environment.

[12] As the day progressed, southerly shear caused the hurricane's structure to begin to degrade some as it shifted its course toward the west-northwest along the southwest edge of a high pressure system.

[16] At 00:00 UTC, August 12, the Japan Meteorological Agency (JMA)[nb 2] and the Joint Typhoon Warning Center (JTWC)[nb 3] initiated advisories on Dora, declaring that it had just crossed the International Date Line and classifying it as Typhoon Dora,[18] becoming only the second tropical cyclone on record to be at hurricane strength in the Eastern, Central and Western Pacific basins, the other being Hurricane John in 1994.

[28] At the same time, Dora was located within an environment of dry air, low vertical wind shear, and neutral 79–81 °F (26–27 °C) sea surface temperatures.

[32][33]While Hurricane Dora did not pose a direct threat to Hawaii, the National Weather Service in Honolulu did issue numerous weather warnings and advisories, especially red flag warnings, for portions of the various islands in expectation of the hurricane helping enhance trade winds in conjunction with an ongoing drought.

[41] On March 20, 2024, the name Dora was retired by the World Meteorological Organization on account of the hurricane's connection to the August 2023 wildfires in Hawaii and will never be used again in the Eastern Pacific basin.
