. In actuality the season exceeded these limits slightly with the formation of Tropical Depression One-E on May 13 and ended on November 11 with the dissipation of Tropical Depression Twelve-E.

This season was below average in activity. In the eastern north Pacific, eleven tropical cyclones formed. Of these, four became hurricanes, one of which were major hurricanes because they reached Category 3 or higher on the Saffir-Simpson Hurricane Scale

In the central north Pacific, one tropical depression formed. In addition, a depression crossed the dateline from the western Pacific before dissipating in this basin. None of these two systems reached tropical storm strength.

In terms of the number of storms, the season was below average. Despite this, there were a large number of landfalls. 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.

Tropical Storm One-E

The season had an early start on May 13 when a tropical wave in the open ocean organized into Tropical Depression One-E. The depression moved west-northwest and strengthened into a tropical storm on May 14. On that day, the tropical storm reached its peak intensity, with maximum sustained winds at 50 mi/h and a minimum central pressure of 1000 mbar (29.5 inHg). Wind shear

 steadily weakened the cyclone until it dissipated early on May 17. This system was the only tropical storm to form in May during the period from 1992-99.

Tropical Storm One-E was not assigned a name because it was determined to be a tropical storm after the season was over. The storm was initially forecast to become a tropical storm, but information available at the time did not warrant the upgrade. Subsequently, wind reports relayed from the US Coast Guard

This tropical cyclone impacted two ships. The first — called the True Blue - was near the fringes of the storm and escaped. The other — the trimaran Solar Wind - provided wind observations until communications with the vessel were lost after 0600 UTC on May 14. Despite a search by the US Coast Guard, the ship and its two-person crew was never found.

Tropical Depression Two-E

 developed into a tropical depression. The disturbance was not readily traceable back to a tropical wave from the Atlantic. On its first day of its existence, Tropical Depression Two-E was a well-organized system with maximum sustained winds of 35 mi/h and a minimum central pressure of 1006 mbar (29.7 inHg). As it slowly moved west, Two-E experienced a few intermittent bursts of convection. However, the depression gradually became less organized during the remainder of its life. On May 18, the cyclone's organization deteriorated markedly until it dissipated the next morning.

Tropical Depression Two-E never threatened land. Consequently, there were no reports of deaths or damage.

 on June 23 and almost immediately went back out to sea. Alma slowly paralleled the coast as the topography disrupted the cyclone's circulation. Alma weakened to tropical storm intensity on June 24 and to tropical depression intensity on June 26. It dissipated the next day. Alma's maximum winds were 105 mph (165 km/h) and Alma's minimum pressure was 969 mbar (28.6 inHg).

Hurricane Boris

On June 27, a tropical wave developed convection and became Tropical Depression Four. It moved north and slowly intensified. The rate of intensification increased and the depression became a tropical storm on June 28. 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). Boris then made landfall on June 29 about midway between Lázaro Cárdenas and Acapulco

.

Hurricane Boris was, in general, a well-forecast storm. Due to the short time when the system was at or above tropical storm intensity, long-range forecasts were not verified. The average errors were 116 mi (186.7 km) at one and a half days in the future. Boris caused at least five deaths. One person was killed in Tecpan. Nearby, three other people drowned and five fishers were missing. In Acapulco, a child was killed when a roof collapsed. Rain was heavy throughout the impacted region, with the highest totals in Guerrero

 on July 3. It peak strength, which occurred at landfall, was 70 mph (112.7 km/h) and 991 mbar (29.3 inHg). Cristina dissipated over the mountains of Mexico on July 3.

As a whole, both Cristina's intensity and track were well-forecast. However, the tropical cyclone's short life made verification of a small number of forecasts limited. When Cristina was approaching, the Mexican government issued a tropical storm warning for the coast between Tapachula

Tropical Storm Cristina killed one person, a fisherman, who was aboard a boat caught at sea. Another person from that boat was missing, and a third individual was rescued. Eleven other fishing boats, with a total of twenty-two people aboard, were missing. Their fate is unknown. The National Hurricane Center received no reports of damage due to Tropical Storm Cristina; however flooding due to storm surge

 and damage from wind. It also produced rain.

Tropical Depression Six-E

On July 4, a persistent area of thunderstorms organized into a tropical depression. Weak steering currents slowly moved it northwest. Easterly wind shear inhibited the development of the system. Despite the wind shear, Six-E was forecast to strengthen into a tropical storm, but it instead weakened to a swirl of clouds and advisories were ended on July 5. Tropical Depression Six-E dissipated on July 6. At its peak strength, Six-E had winds of 35 mph (56.3 km/h) and a central pressure of 1003 mbar (29.6 inHg).

This cyclone never came ashore. Consequently, no reports of damage or deaths were received by the National Hurricane Center.

. 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.

Douglas's strengthened over the next two days as it turned west-northwest, paralleling the coast of Mexico. It reached its peak intensity on August 1, with winds of 135 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

, an area of disturbed weather containing convection formed on September 23. It moved westward without incident until September 27, when it developed stronger convection and became Tropical Depression Ten-E. Immediately thereafter, it strengthened into a tropical storm and was named Genevieve while it continued its westward track.

Genevieve slowly got better organized, and reached its peak intensity of 999 mbar (29.5 inHg) and 50 mph (85 km/h) on September 29. The tropical storm then turned to the west-southwest

, and the tropical storm weakened to a tropical depression on October 1. On October 6, the shear temporarily weakened, and Tropical Depression Genevieve restrengthened into a tropical storm. The cyclone's wandering continued, and it entrained dry air. This dry air weakened the system to a depression for a second time on October 8, and Genevieve dissipated the next day. Brief flare-ups of convection could still be seen for a few days thereafter.

s indicated a northwesterly track that never happened, and also over-intensified the system. In addition, advisories on Tropical Depression Genevieve were discontinued on October 3, and only resumed three days later. Later analysis determined that Genevieve had been a tropical depression for this whole time.

Tropical Storm Genevieve never came near land, and consequently no watches or warnings were required for any location. The tropical cyclone had no impact on any land.

Hurricane Hernan

On September 30, a tropical wave organized into Tropical Depression Eleven-E. Gradual strengthening ensued, and the depression strengthened into a tropical storm twelve hours later and was named Hernan. Hernan's initial track was to the west, but the system gradually started to recurve. Its center of circulation reformed, and Hernan briefly turned to the northwest again. By October 2, and Hernan was close to the coast. It strengthened into a hurricane that day. Late on October 2 and early on October 3 Hernan closely paralleled the coast. 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. At its strongest, Hurricane Hernan had winds of 85 mph (140 km/h) and a central pressure of 980 mbar (28.9 inHg).

Tropical Depression Twelve-E

A system acquired enough convection and became organized enough to be considered a tropical depression on November 7. Although the environment was initially favourable and the system was almost upgraded into a tropical storm as was forecast, wind shear kept the cyclone weak. Its convection was eventually destroyed and advisories were ended on November 10. Twelve-E dissipated on November 11 and no deaths or damages were reported.
