Typhoon Rammasun, known in the Philippines as Typhoon Glenda, was one of only two Category 5 super typhoons on record in the South China Sea, with the other being Pamela in 1954. Rammasun had destructive impacts across the Philippines, South China, and Vietnam in July 2014. It was the seventh tropical cyclone of the season to be named by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). Rammasun is a Siamese word for thunder god. After Lingling and Kajiki earlier in 2014, Rammasun became the third tropical cyclone, and first typhoon to directly impact the Philippines in 2014. The storm formed in the Intertropical Convergence Zone, an area near the equator where the northeast and southeast trade winds come together, and slowly drifted northwest. Having passed through the islands of Micronesia, the system turned west and quickly moved under the influence of a subtropical ridge (STR). Rammasun posed a significant threat to the Philippine island of Luzon, as it was expected to reach typhoon intensity before making landfall there. Though initially forecast to make landfall in Cagayan Valley, the storm followed a more westerly path and was later forecast to make landfall in the Bicol Region and then pass through Bataan and Zambales before brushing past Metro Manila.
