1927 Pacific Typhoon Season

In 1927, there were 27  tropical cyclones observed in the western Pacific Ocean, north of the equator and west of the 180th meridian. Many of these storms affected the Philippines, China, and Japan, collectively leaving 15,952 fatalities. The strongest storm of the year also had the lowest barometric pressure recorded in a tropical cyclone worldwide at the time. On August 18, the Dutch steamship ''Sapoeroea'' recorded a barometric pressure of 886.7  millibar (26.185  inches of mercury) about 740 kilometres (460 miles) east of Luzon. This typhoon later struck near Hong Kong, where it halted transportation, wrecked buildings, and killed 15 people.

The first storm of the year originated near the Caroline Islands on February 12, which capsized the freighter ''Elkton'' and caused the loss of its crew of 36 people. Storms were observed in each subsequent month of the year. In May, a typhoon wrecked the passenger ferry ''SS Negros'' near the Philippine province of Romblon, killing 108 people. A typhoon in July killed around 10,000 people in China, mostly related to mountain flooding near Zhangzhou, leaving around 100,000 people homeless. A month later, another landfalling typhoon in China killed about 5,000 people and damaged nearly 20,000 houses. In September, an intense typhoon moved through Japan around the same time that an undersea earthquake affected the region; the concurrent disasters killed about 600 people, after a 3  metre (10 foot) tsunami washed away boats and houses along the coast. Another Chinese typhoon in September killed 5,000 people. The final storm of the year dissipated on December 19 to the west of the Philippines.

Season summary

The Hong Kong Observatory (HKO) tracked 21 tropical systems during the year, then referred as "depressions". Of these storms, 19 were estimated to have attained typhoon status, which has maximum sustained winds of at least . The HKO distributed storm warnings to 86 weather stations or officials, including by telephone for the first time. During the year, 11 tropical cyclones passed near the Philippines, of which seven crossed land; four of these were typhoons. The fewer than average storms in the archipelago resulted in lower than average rainfall in western Luzon. The Philippines government insurance fund claimed ₱16,149.25 in damages, mostly related to a radio station that was destroyed in Baler.

Systems

February–June

The first tropical cyclone observed in 1927 was noted on February 12 southeast of Yap in the Caroline Islands. It moved west-northwestward, passing near Ngulu Atoll on February 14. The storm was last observed on February 16 after recurving to the northeast. Yap recorded a barometric pressure of , suggesting that the storm was a typhoon. On February 15, the freighter ''Elkton'' sent a distress signal amid the storm about northwest of Guam. By the time the S.S. ''Liberator'' arrived the next day, it only observed a oil patch; this suggested that the ship, its crew of 36 people, and the $1 million worth of sugar aboard, had capsized. The United States Navy deployed four destroyers from Manila, but was unable to find the wreckage.

A short-lived tropical cyclone was first observed on March 19, east of Mindanao in the Philippines. The system progressed northwestward through the Eastern Visayas, dissipating on March 20 over Masbate. On April 1, a tropical storm formed southwest of Taiwan, and progressed northeastward, passing between the island and the northern Philippines; the storm was last noted on April 4 south of Japan.

As early as May 22, a tropical cyclone existed east of the Philippine island of Samar. Tracking west-northwestward, the storm was at typhoon intensity when it struck eastern Luzon on May 26 near Baler, where a pressure of was recorded. The center became disrupted while traversing the island, emerging into the South China Sea near Dagupan. It slowed to a northwest drift, dissipating on June 1 southeast of China. On May 28, the passenger ferry ''SS Negros'' foundered near Romblon during the typhoon, with the loss of 108 of the 178 people on board.

Another storm appeared east of the Philippines on May 26, located south of Yap. Initially, the system moved west-northwestward, passing over Palau, where 80% of houses were destroyed; damage was estimated at Â¥400,000. The storm turned to the north-northwest, then later curved back to the west-northwest, reaching the Balintang Channel north of Luzon on June 2. That day, the town of Basco, Batanes in the waterway recorded a pressure of . On June 3, the storm crossed over Taiwan and recurved to the northeast. It was last noted on June 6 just south of the Japanese island of Kyushu.

On July 17, the typhoon struck southeastern Taiwan and moved across the southern portion of the island, where Hengchun recorded a barometric pressure of . Crossing the Taiwan Strait, the storm entered southeastern China near Xiamen on July 17, and dissipated the next day.

On July 20, a tropical cyclone developed east of Luzon and proceeded to the west-northwest. Three days later, the storm struck Isabela province in eastern Luzon. It moved northwestward once in the South China Sea, passing near Pratas Island. On July 25, the SS ''President Madison'' encountered the storm near the coast of China, reporting hurricane-force winds and a minimum pressure of . That day, the typhoon moved ashore near Hong Kong, where winds reached . Also near Hong Kong, a Chinese junk sank, killing 191 people, while passengers were rescued by the steamer ''Wing On''. The storm curved to the southwest over land, dissipating on July 27. Flooding along the Jiulong River killed 10,000 people by drowning, mostly in mountainous areas near Zhangzhou. The floods left another 100,000 people homeless, and caused $2 million in damages.

August

The August issue of the '' Monthly Weather Review'' journal noted a small typhoon west of the Ryukyu Islands from August 2–4, moving northward and "of no great importance." A tropical cyclone was first reported on August 6 east of Luzon and north of Yap. It moved to the northwest, turned northeastward, and curved back to the northwest through the southern Ryukyu Islands. As it approached the eastern coast of China, the typhoon turned more to the north, and later crossed the Korean peninsula; it was last reported on August 10 off the east coast of the peninsula.

On August 13, a tropical cyclone was observed south of Guam. It moved west-northwestward and attained a great intensity. On August 18, the Dutch steamship ''Sapoeroea'' recorded a barometric pressure of about east of Luzon. This was the lowest pressure recorded in a tropical cyclone at the time, until a Hurricane hunters plane released a dropsonde into Typhoon Ida in 1958 and recorded a pressure of . Early on August 19, the typhoon passed near Aparri in northern Luzon, which recorded a pressure of . The storm's strong winds affected Cagayan, Mountain, Ilocos Norte, and Ilocos Sur provinces. Progressing into the South China Sea, the typhoon approached within of Pratas Island on August 20, where Force 11 winds were recorded. Later that day, the storm passed about south of Hong Kong, where wind gusts reached . In Cheung Sha Wan, the typhoon wrecked 120 buildings, and the entire shanty town in Kowloon Tong was ruined. Ferry and tram service was halted, and a bus was overturned on Salisbury Road. Throughout Hong Kong, 11 boats were wrecked, 15 people were killed, and another 22 others were injured. Continuing across southern China, the storm was last observed on August 22.

As early as August 19, a tropical cyclone was near and south of Guam. Its track curved from the west-northwest to the north, drifting at times west of the Marianas Islands.

A typhoon was first observed on September 9 northeast of the Philippines. Passing Guam two days later, its northward track shifted to the northeast toward Japan. The typhoon struck Kyushu on September 13, described in the ''Monthly Weather Review'' as the "most severe felt there in recent years." Around the same time, an underwater earthquake affected the region, which produced a tsunami that washed away buildings along the coast and carried boats two miles inland. Newspapers reported nearly 600 fatalities during the typhoon and earthquake. River flooding in ÅŒmura inundated 5,000 houses, leaving 15,000 people homeless. The storm ruined rice fields, causing prices to increase. Across Kyushu, the typhoon flooded or wrecked the roofs of thousands of homes.
