It officially started on May 15, 1969, in the eastern Pacific Ocean (east of 140°W in the Northern Hemisphere), and ended on November 30, 1969.

These dates conventionally delimit the period of each year when most tropical cyclones form east of this region of the Pacific.

At the time, Ava was the latest forming first named storm in any Eastern Pacific season on record.

In this season, only three storms (Ava, Bernice, and Florence) were operationally categorized as tropical depressions at the first advisory.

Ava then began to decelerate in forward motion, and after the storm had turned to a more northward path, reached its peak intensity of 50 mph (80 km/h) on July 5.

[2] On August 4, a relatively unusual cirrus cloud formation resembling a pinwheel formed over the center of the storm.

The formation had provided efficient evidence that the system had developed into a tropical storm, bypassing the depression stage.

[1][2] Doreen continued a northwest track, deepening along the way, and on August 5, a ship reported 70 mph (115 km/h) winds with a 993 mb pressure near the storm center.

A very short lived storm, Tropical Depression Seven formed off the coast of Mexico on August 5, dissipating the same day.

However, on August 21, a circulation developed at around 14° N and was apparent on weather maps, but at the time, no major winds were suspected near the center.

[2] A low-pressure area that persisted off the coast of Mexico produced squalls during late August and early September.

Florence continued northward, strengthening to near-hurricane intensity with peak winds of 70 mph (115 km/h) and a pressure of 992 mb.

The remains of what was formerly Hurricane Francelia crossed over Central America and contributed to an area of convection that formed 120 miles southwest of Acapulco.

Glenda continued its motion northwest while increasing in strength, with a closed eye being noticed on September 9.

Glenda's time as a hurricane was very short lived as it was downgraded to a storm just six hours after the initial upgrade.

The information is unclear on how Heather developed but she was first noticed on September 18 1,000 miles southwest of La Paz, Baja California.

Like Claudia and Doreen, Heather's lifespan was mostly monitored by satellite and Air Force recon because of a lack of shipping in the general area.

[2] From where it first grew, Heather moved west-northwest, reached its peak intensity of 65 mph (105 km/h) winds, and then eventually weakened to a depression on September 22 and was considered dissipated.

[3] Heather would begin to accelerate, followed by a westward motion on September 25, dissipating later that day, this time for good.

However, a bulletin from a different source provided with a mosaic image was the evidence used in giving the system the name Irah and treating it as a tropical storm.

Later, another ship reported 45 mph (70 km/h) winds in the vicinity, prompting the advisories that Tropical Storm Jennifer had formed.

Jennifer also caused a ferry and twelves boats used for fishing shrimp to be washed up in the Mazatlán Harbor.
