The broad low gradually organized as it moved west-northwestward, and it became Tropical Storm Narda early on September 29 while located off the southern coast of Mexico.

Narda quickly strengthened, and reached its peak intensity with winds of 50 mph (85 km/h) that day before making a second landfall along the northwestern coast of Mexico.

On September 23, the United States National Hurricane Center (NHC) noted the potential for an area of low pressure to form south of the southern coast of Mexico over that coming weekend.

[4] Early on the following day, the disturbance's circulation became better defined, and an increase in convective banding occurred over the western portion of the broad system.

[5] Moving slowly northward toward the southern coast of Mexico, Narda gradually became better organized and strengthened to an initial peak intensity with winds of 45 mph (75 km/h) as banding features became evident.

[9] However, the cyclone continued to produce a large area of deep convection near and west of its center, and it soon restrengthened into a tropical storm at 15:00 UTC that day.

The Aquiles Serdán bridge connecting Cabo Corrientes with several communities collapsed due to flooding, and there were two reported fatalities as a result of the storm in Jalisco.
