A broad area of low pressure accompanied by showers and thunderstorms developed along the wave around 275 miles (443 kilometres) south of Acapulco, Mexico.

[1] The low developed enough convection late on October 14 to be declared Tropical Depression Fifteen-E while located about 435 mi (700 km) southwest of Colima, Mexico.

[2] The depression was embedded within a broad, low-level cyclone with weak steering currents that caused Fifteen-E to drift southward for the next 30 hours.

This prompted the National Hurricane Center to upgrade the depression to Tropical Storm Kiko as it drifted about 430 mi (690 km) southwest of Manzanillo, Mexico.

[7] As the ridge pushed the storm away from the coast, weaker wind shear and warm sea-surface temperatures allowed Kiko to gradually intensify.

The storm reached its peak intensity of 70 mph (110 km/h) 991 mbar (hPa; 29.28 inHg) late on October 20 while located around 175 mi (282 km) west-southwest of Manzanillo, Mexico.

[11] That evening, Kiko was downgraded to a tropical depression as strong wind shear removed convection from the storm's center and exposed the low.

[12] As the depression moved over a dryer and more hostile area, two inhibiting factors for development of tropical cyclones, it slowly weakened.

[1] It lost almost all convection and degenerated to a remnant low-pressure area on October 23, and the National Hurricane Center issued its final advisory that night.

[17] As the storm neared land, a ridge over Mexico prevented Kiko from coming ashore, resulting in far less damage than forecast.
