The strongest of these storms were Glenda and Mona, which both had 85 mph (135 km/h) winds. The first storm, Emily, made landfall near Manzanillo, Mexico as a Category 1 hurricane. The next hurricanes, Florence and Glenda, stayed far away from land. Jennifer-Katherine made landfall on Baja California as a tropical depression on September 18. Tropical Storm Irah affected Hawaii as a tropical depression. An unnamed tropical storm curved round Hawaii from 2–8 August. Lillian became post-tropical shortly before making landfall on September 29 with winds of 50 mph. Mona, the final storm of the season made landfall around about the same area as Lillian did with winds of 85 mph.

Hurricane Emily

Category 1 hurricane (SSHWS)
Duration	June 29 – June 30
Peak intensity	85 mph (140 km/h) (1-min); 996[1] mbar (hPa)

Hurricane Emily formed on June 29, while moving west. It then turned to the north and dissipated over the mountainous regions of Mexico.

Hurricane Florence

Category 1 hurricane (SSHWS)
Duration	July 14 – July 17
Peak intensity	85 mph (140 km/h) (1-min); 992[1] mbar (hPa)

Hurricane Florence followed a nearly-due west track, as it persisted to move away from land, and eventually weakened and dissipated without any effects on a landmass.

Hurricane Glenda

Category 1 hurricane (SSHWS)
Duration	July 19 – July 21
Peak intensity	85 mph (140 km/h) (1-min); 997[1] mbar (hPa)

Hurricane Glenda stayed at sea.

Tropical Storm Four

Tropical storm (SSHWS)
Duration	August 2 – August 8
Peak intensity	50 mph (85 km/h) (1-min);

Tropical Storm Four stayed over the ocean. Several vessels encountered gale-force winds in this storm from the 8th through the 10th as it proceeded northward across the shipping lanes. On August 12, the remnants of the cyclone dissipated near 50N 165W.

Tropical Storm Jennifer–Katherine

Tropical storm (SSHWS)
Duration	September 9 – September 18
Peak intensity	50 mph (85 km/h) (1-min); 996[1] mbar (hPa)

Tropical Storm Jennifer–Katherine moved through the Eastern Pacific in mid-September. It moved northward, and hit Baja California on September 18, bringing heavy rain to Southern California. A total of 6.5 inches (165 mm) fell in the mountains of southern California from the storm.^[2] The storm had two names operationally because the NHC had assumed that Jennifer dissipated and that Katherine was a new storm, but reanalysis revealed that it was one storm.

Tropical Storm Irah

Tropical storm (SSHWS)
Duration	September 12 – September 21
Peak intensity	50 mph (85 km/h) (1-min); 999[1] mbar (hPa)

Irah peaked at a tropical storm and made a direct hit on Hawaii as a tropical depression.

Tropical Storm Lillian

Tropical storm (SSHWS)
Duration	September 24 – September 29
Peak intensity	50 mph (85 km/h) (1-min); 991[1] mbar (hPa)

Tropical Storm Lillian paralleled the Mexican coast. It was originally moving to the north-west, but turned to the west-northeast on September 28, before making landfall on Western Mexico as a tropical storm.

Hurricane Mona

Category 1 hurricane (SSHWS)
Duration	October 17 – October 19
Peak intensity	85 mph (140 km/h) (1-min); 961[1] mbar (hPa)

Storm names

Main articles: Tropical cyclone naming, History of tropical cyclone naming, and List of historical tropical cyclone names

The following names were used for tropical storms that formed in the North Pacific Ocean east of 140°W during 1963. The names came from a series of four rotating lists. Names were used one after the other without regard to year, and when the bottom of one list was reached, the next named storm received the name at the top of the next list.^[3]

Emily Florence Glenda

Hazel Irah Jennifer

Katherine Lillian Mona

Had any tropical storms formed in the North Pacific between 140°W and the International Date Line in 1963, their names would have been drawn from the Western Pacific typhoon naming list.^[3]
