These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean.

Much of the season's activity was clustered near the coast of Southwest Mexico, with four hurricanes and one tropical storm making landfall along it.

Douglas developed in the Caribbean Sea, within the Atlantic basin, as Hurricane Cesar, before crossing into the Pacific as a tropical storm.

[4] In addition, one Atlantic hurricane, Cesar, crossed into the Pacific as a tropical storm, at which time it was renamed Douglas.

Of note is the fact that three tropical cyclones approached close to, or made landfall on, Mexico during a ten-day span from June 23 to July 3.

On that day, the tropical storm reached its peak intensity, with maximum sustained winds at 50 mph (80 km/h) and a minimum central pressure of 1,000 hPa (29.53 inHg).

[14] Subsequently, wind reports relayed from the US Coast Guard to the National Hurricane Center suggested that this cyclone was a tropical storm.

On its first day of its existence, Tropical Depression Two-E was a well-organized system with maximum sustained winds of 35 mph (56 km/h) and a minimum central pressure of 1,006 mbar (29.7 inHg).

[16] Hurricane Alma was the first of three consecutive storms to come close to, or make landfall on, the Pacific coast of Mexico during a ten-day span.

Boris reached hurricane intensity on June 28 and peaked with winds of 90 mph (150 km/h) and a central pressure of 979 mbar (28.9 inHg).

Due to the short time when the system was at or above tropical storm intensity, long-range forecasts were not verified.

[9] When Cristina was approaching, the Mexican government issued a tropical storm warning for the coast between Tapachula and Punta Maldonado on July 2.

[9] Tropical Storm Cristina killed one person, a fisherman, who was aboard a boat caught at sea.

[21] Despite the wind shear, Six-E was forecast to strengthen into a tropical storm,[22] but it instead weakened to a swirl of clouds and advisories were ended on July 5.

Continuing Cesar's nearly due-west heading, it was still a tropical storm when it entered the Pacific on July 29, and quickly regained hurricane status.

It reached its peak intensity on August 1, with winds of 130 mph (215 km/h) and a central pressure of 946 mbar (27.9 inHg), making it the strongest hurricane of the season at a Category 4 strength.

[5] Hurricane Douglas brought up to 6 in (150 mm) of rain on the south coast of Mexico and resulted in a 4-ft (1.2-m) storm surge.

At its strongest in the central north Pacific, Tropical Depression Seventeen-W had winds of 35 mph (56 km/h) and a pressure of 1,000 mbar (30 inHg).

No re-intensification occurred after the system entered the eastern Pacific, and it dissipated early the following day, just west of San Juanito in the Islas Marías.

On September 3 and 4, Elida came close to the southern tip of the Baja California Peninsula at its peak intensity of 994 mbar (29.4 inHg) and winds of 65 mph (100 km/h).

[28] Moderate to heavy rains fell in association with the tropical cyclone across southwest Mexico and the Baja California Peninsula, with the maxima falling at San Marcos/Compostela in southwest mainland Mexico, which measured 6.60 in (168 mm), and a maximum for Baja California of 3.88 in (99 mm) at La Poza Honda/Comondu.

[28] The precursor disturbance to Fausto was first noticed over Venezuela as early as August 31, and may have been related to the tropical wave that spawned Hurricane Fran.

[31] Fausto intensified rapidly after it reached hurricane intensity on the September 12, peaking with sustained winds of 105 knots (194 km/h) and a minimum central pressure of 955 mb.

[31] On September 14, the storm turned northeastward across the Gulf of California, and dissipated inland over the Sierra Madre range after its second landfall as a hurricane.

Heavy rainfall was accompanied with the passage of this cyclone, with a storm total of 18.50 inches (470 mm) reported at San Vicente de la Sierra.

Interaction with land weakened the cyclone, and when Hernan made landfall on October 3 near Barra de Navidad, Jalisco, it was only a minimal hurricane.

Land weakened the cyclone, and by the time it emerged into the ocean north of Puerto Vallarta, it was so disorganized that it dissipated on October 5.

[36] Although the environment was initially favourable and the system was almost upgraded into a tropical storm as was forecast,[37] wind shear kept the cyclone weak.

[42][43] For storms that form in the North Pacific from 140°W to the International Date Line, the names come from a series of four rotating lists.

It includes their name, duration (within the basin), peak classification and intensities, areas affected, damage, and death totals.
