'''Severe Tropical Storm York''', also known in the [[Philippines]] as '''Neneng''' was a storm that formed on September 1999. It brought severe impacts to the [[Philippines]] and southeastern [[China]], causing 35 deaths. Considered as the worst storm to hit Hong Kong since [[Typhoon_Ellen_(1983)|1983]], York was first noted as a tropical disturbance over the [[Philippine Sea]] on September 9th, 1999, and became a tropical depression three days later on September 12. Initially, the initial intensity of the system has been at the lower limit of tropical depression intensity, until the formation of a new center in northern [[South China Sea]] west of [[Luzon]] the following day. Despite identified as a tropical storm the following day, York's track was erratic and remained stationary for a while, until landing near [[Hong Kong]] as a severe tropical storm or minimal typhoon on September 16. Afterward, York weakened to a tropical storm and quickly weakened, degenerating into a remnant area of low pressure soon after on the following day.

Severe Tropical Storm York, also known in the Philippines as Neneng was a storm that formed on September 1999. It brought severe impacts to the Philippines and southeastern China, causing 35 deaths. Considered as the worst storm to hit Hong Kong since 1983, York was first noted as a tropical disturbance over the Philippine Sea on September 9th, 1999, and became a tropical depression three days later on September 12. Initially, the initial intensity of the system has been at the lower limit of tropical depression intensity, until the formation of a new center in northern South China Sea west of Luzon the following day. Despite identified as a tropical storm the following day, York's track was erratic and remained stationary for a while, until landing near Hong Kong as a severe tropical storm or minimal typhoon on September 16. Afterward, York weakened to a tropical storm and quickly degenerated into a remnant area of low pressure soon after on the following day.

York generated heavy rainfall and flooding when it crossed over the Philippines, which claimed the lives of 18 people. Particularly noted for leading to the Hong Kong Observatory issuing the highest No. 10 warning for the first time since 1983, it killed an additional two people in Hong Kong when it passed near the city. A cargo ship were as well reportedly sunk, with some 18,000 homes losing power in the wake of the storm and 4,000 trees uprooted in Hong Kong. Elsewhere in Macau, one person was injured and 120 incidents related to the storm were reported. In the Chinese province of Guangdong, fifteen people lost their lives and produced heavy rainfall. Overall, total damages were estimated to be at least $34 million (USD).

A tropical disturbance developed on September 10 in the western Philippine Sea and was named as Neneng by PAGASA on the same day [1], but initially failed to develop as it interacted with Luzon. The disturbance passed over Luzon and entered the South China Sea, where it became more organized as upper-level outflow became more favorable, and developed into Tropical Depression 21W late on September 11. York intensified into a tropical storm on 13 September, but its movement then became erratic. Heading north at first, York strengthened into a severe tropical storm on September 14, then turned northwestwards before becoming almost stationary and attaining typhoon strength the following night. [2][nb 1] It eventually headed northwest towards the Chinese coastline on September 16 and made landfall to the west of Hong Kong in Zhuhai on the same day. At its peak it was estimated to be as strong as a 130 km/h (80 mph). After landfall, York dissipated into a low pressure area over China the next day. [2][4]

Impact

The Philippines

As the developing depression crossed the Philippines, it brought heavy showers of up to 400 mm (16 inches), which caused some flooding in the Cagayan Valley[5] Eighteen people were killed in landslides in northern Luzon.

Hong Kong and Macao

Upon making landfall at west of Hong Kong, winds gusted to 234 km/h (145 mph) at Waglan Island with hourly sustained winds of 169 km/h (105 mph) recorded. Hurricane-force 10-minute sustained winds were also recorded in Cheung Chau and Sai Kung, storm-force sustained winds were also recorded in Tsing Yi, North Point and Tsim Sha Tsui Ferry Pier, making York one of the strongest storm that affected Hong Kong in post-war period, with near impact in comparison to Typhoon Wanda of 1962 and Typhoon Mangkhut of 2018.[6] Overall in Hong Kong, strong storm to hurricane-force winds were recorded. Both Hong Kong Observatory (HKO) and Macao Meteorological and Geophysical Bureau (SMG) issued the No.10 hurricane signal, which lasted 11 and 8.5 hours respectively, both post-war records in terms of lasting time.

In Hong Kong, a man was found dead in Cheung Chau 64 hours after being swept away by waves. Another man was killed by debris blown by high winds in Tseung Kwan O. Injuries tallied to 500 in the city in which 11 were severely injured, making York the storm that led to most injuries in the city since World War II. In Wan Chai, more than 400 pieces of glass were blown off from several buildings. A tower cane collapsed and hit a nearby building in the same region, forcing 25 people to evacuate due to suspected gas leak. 64 reported flooding cases were reported during York, with over 340 hectares of farmland flooded and forced over 300 people to evacuate. A total of more than 800 signboards more than 4,000 trees collapsed, with a large number of roads blocked by fallen trees and tattered signboards seen everywhere on the streets. [7] Electrical shortages were reported in several places in Hong Kong, with water shortages as well reported in Sai Kung and Cheung Chau. Transportation came to a stall with at least 470 flights delayed or cancelled due to bad weather, affecting 80 thousand passengers. Damages could total to as high as several billion Hong Kong dollars. [2]

In Macao, York led to violet winds in the town, with sustained winds of 108 km/h (67 mph) and gusts as high as 181 km/h (112 mph) recorded in Taipa Grande. 120 incidents of different kinds were reported during the storm, with a chimney collapsing in Zona Norte.[8] At least one injury were reported during the storm. Transportation came to a complete halt with schools, shops and most casinos temporarily closed. 30 flights were cancelled or delayed.

Mainland China

Throughout the affected areas, at least 15 deaths and 700 injuries were reported. Direct economic damages tallied up to 200 million RMD (30 million USD). [2] Zhuhai was particularly affected due to York landing at Xiangzhou District in the city, with a total of 71 people in Zhuhai injuries that require hospital treatment reported. Schools and work were largely suspended, with transportation as well coming to a halt. Electricity shortages were recorded which affected thousands of civilians. 900 trees and 400 scaffolds, billboards and windows were blown down by high winds. The direct economic losses caused by York to Zhuhai amounted to about 100 million RMD. [9]
