Information About

1964 Pacific Typhoon Season




The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line . Storms that form east of the date line and north of the equator are called hurricanes; see 1964 Pacific Hurricane Season . Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center . Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical And Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.




STORMS

52 tropical depressions formed this year in the Western Pacific, of which 39 became tropical storms. 26 storms reached typhoon intensity, of which 7 reached super typhoon strength.


Typhoon Ida

The interaction between the polar trough and an easterly wave developed into Tropical Depression 15W on August 2 . It moved to the west-northwest, quickly strengthening into a tropical storm later on the 2nd and into a typhoon on the 4th. Ida rapidily intensified to a 155 mph super typhoon on the 6th, and struck northeastern Luzon at that intensity that night. After weakening over the island, Ida turned to the northwest and hit southeastern China near Hong Kong on August 8 as a 100 mph typhoon. The storm killed 75 people, and caused moderate to heavy damage on its path.


Typhoon Ruby

Typhoon Ruby, which formed on September 1 to the northeast of Luzon , rapidly intensified on September 5 to a peak of 140 mph winds. It hit near Hong Kong just hours later, and dissipated on the 6th over China. Ruby caused over 730 fatalities and heavy damage.


Super Typhoon Wilda

Super Typhoon Wilda, having started on September 19 and reaching a peak of 175 mph on the 21st, steadily weakened after its peak. It turned northward and northeastward, and made landfall on southern Japan on the 24th as a 115 mph typhoon, and became extratropical the next day. Wilda left 42 dead or missing from its heavy flooding.


Typhoon Dot

Typhoon Dot hit northern Luzon on October 9 as an 80 mph storm. It continued northwestward, and reached a peak of 100 mph before hitting near Hong Kong on the 13th. Dot dissipated quickly, after leaving 36 dead or missing, with 85 people injured from the typhoon.


Super Typhoon Louise

The monsoon trough spawned Tropical Depression 46W on November 15 east of the Philippines. It moved westward, reaching tropical storm status later on the 15th and typhoon status on the 16th. Louise rapidly intensified, and peaked at 190 mph on the 18th. The super typhoon weakened slightly to 160 mph before hitting the southeast Philippines on the 19th. Louise dissipated over the archipelago, after causing 400 fatalities.
